		The valve sleeve is rotated so that the oxygen fuel and air fuel mixture pass into the detonation chamber when the valve sleeve ports register or align with the detonation chamber ports.
		Vanes 53 are oriented at different angles and protrude from valve sleeve 35 to assist in mixing of the gaseous fuel in the forward and rearward sections of annular space 44.
		Valve sleeve 35 is sealingly carried on the exterior of detonation chamber 13 by a pair of forward circular seals 55 and rearward circular seals 57.

	Sleeve valve - Wikipedia, the free encyclopedia
		The sleeve valve is a type of valve for piston engines that has a number of advantages over the more common poppet valve, used in most engines, as well as disadvantages that have precluded its widespread adoption to date.
		In a normal engine using poppet valves, the valves are opened by the camshaft pushing down on the top of the valve, sometimes via a long pushrod and rocker taking the power from the crankshaft area to the top of the cylinders.
		Otherwise a single sleeve is operated by a crank driven from the crankshaft, the sleeve moves in a circular path opening the cylinder ports in upper part of the circle.

		Sleeve valves are a way of building valves for piston engines that have a number of advantages over the more common poppet valve, used in most engines.
		Sleeve valves were common in the 1940s, notably in aircraft engines, but fell from use quickly due to their tendency to burn considerable amounts of lubricating oil.

		In the sleeve valve assembly 114, the connecting rods 248 are screwed into a member 276 that is threadably coupled to a sleeve member 278 that inclues a seal 280 to block fluid from flowing when the sleeve valve assembly is in its closed position as illustrated.
		2-4, the sleeve valve 114 and the ball valve 116 are shown to be mechanically coupled such that one mechanism may be used to actuate both valves 114 and 116, an alternative embodiment contemplates separate mechanisms to actuate the sleeve valve 114 and the ball valve 116.

	Bristol Perseus - Wikipedia, the free encyclopedia
		In short, the sleeve valve replaced the normal poppet valves in the engine with a rotating sleeve inside the cylinder.
		The sleeve is also much easier to "drive" than the poppet, there are no pushrods or rockers needed just a gear at the base of the cylinder, so it is a much better design to use in "dense" two-row engines where the pushrods otherwise take up considerable space.
		It was in these designs that the advantages of the sleeve valve were finally put to good use, and by war's end the Centarus was one of the most powerful engines in the world.

	The knight Sleeve valve
		Although the principle of the sliding or sleeve valve was not original with Charles Y. Knight, it was his patented version that caught on with a number of automobile manufacturers starting with English Daimler in their 1909 models.
		These sleeves are moved up and down in the cylinder, so that the ports coincide at determined moments with others provided in each cylinder wall, thus establishing the connection with the inlet or the exhaust manifold.
		However, the sleeve valve too had its problems, among them high cost,oil consumption and internal inertia (the criticism that they were not amenable to high speeds is belied by many excellent racing records compiled by Knight engined cars, including a flawless 5th-place performance by a Mercedes-Knight in the 1913 Indy 500).

	CanadianDriver: Motoring Memories - Willys-Knight and the Sleeve Valve Engine
		The sleeve valve principle was invented by Charles Yale Knight of Chicago in 1903 to replace the noisy poppet valve then used in engines.
		Those valves, which opened mechanically (or in very early engines, by atmospheric pressure), and closed by a spring, were noisy, prone to burning and leakage, and subject to bouncing and floating (getting hung up between open and closed).
		Sleeve valves lost their advantage, and although they would continue to be used for several years, especially in aircraft applications, they gradually disappeared.

		A seat surface complementarily fitted to the sleeve is formed with a pair of axially offset apertures alignable with the apertures of the sleeve in respective angularly offset positions of the sleeve.
		In addition two such valves must be provided for each cylinder, one to connect it to the exhaust manifold that carries away spent gases during the exhaust stroke and one to the intake manifold that supplies air during the intake stroke.
		The sleeve 20 is formed with a pair of axially spaced and radially throughgoing apertures 20a and 20b spaced apart axially the same as the apertures 22a and 22b and is internally provided with a transverse partition 20c between them.

		The sleeve is a free floating cylinder liner that ocillates up and down as well as twists back and forth to line up a port in the sleeve with the intake or exhaust manifold opening in the cylinder proper.
		With the sleeve valve in place the clyinder sleeve (the sleeve the piston slides against) must be thinner, and is more isolated from the cooling medium.
		The sleeve was on a crankshaft with a ball end connection that raised and rotated the sleeve.

	SHANGHAI KARON VALVES MACHINERY CO.,LTD.
		Operation of the KARON Multi-jet Sleeve Valve is based on dissipating energy by throttling the water through a unique multi-jet tapered nozzle pattern that causes the fluid jet from each individual nozzle to collide with other jets.
		In the Karon Model 410 Angle Pattern Sleeve Valve this uniform peripheral pressure is maintained by offsetting the throttling sleeve from the axis of the inlet chamber in such a way that the chamber becomes progressively smaller as the water moves through the chamber.
		Vibration is eliminated in the KARON Sleeve Valves by eliminating velocity head loss in front of the nozzles and by using advanced designs to insure that the cavitation that may occur is confined to the center of the throttling sleeve, completely surrounded by water.

	Pinch Valves
		Pinch valves should be designed so that they fit easily between flanges of the connecting piping without having to add extra space needed for compression of flanged sleeves when the valve has to be removed for service.
		Therefore, where sleeves have a simple cylindrical shape and no flanges on either end, the end flanges of the valve housing should be available in the appropriate material or with a flange liner for compatibility.
		The volume of the annular space between the housing walls and the sleeve determines the volume of compressed air or liquid required to close the valve and the smaller this volume is, the less fluid exchange is necessary and less energy is expended during cycling.

	Steam Brake Valve
		The friction force between the plug and the sleeve is proportional to the pressure on the surface multiplied by the surface area.
		Pressure Between Sleeve and Body: The total force (pressure X surface area) between the plug and sleeve is the same as between the sleeve and the body.
		After trying several sleeves a little thought revealed that the sleeve OD area was nearly twice the ID area hence the sealing pressure on the OD was roughly half the sealing pressure on the ID. No wonder the the sleeve-body interface was the most likely to leak.

	Pioneer Sleeve Valve Engine
		The sleeve valve story starts in the early 1900s when Chicago based engineer Charles Yale Knight (1868 - 1940) began experimenting with cylindrical valves in an effort to circumvent the problems of weak valve springs and burnt poppet valves that were plaguing the automobile engines of the time.
		McCollum describes his invention as follows, “The valve gear employed is of the type which has both lateral and reciprocatory movements in order to control the inlet and exhaust and according to the present invention, such valve is arranged substantially coaxial with the piston.
		To operate the valve, the McCollum cylinder is fitted with normal pushrods and rockers, except that the “inlet” pushrod and rocker causes the sleeve to go up and down while the “exhaust” apparatus causes the sleeve to rotate.

		Key points to note are that the sleeve moves with an elliptical motion, and is moving relative to the piston at all times.
		There are, or were, heat transfer problems with the sleeves, due to the gap between the sleeve and the engine cylinder it ran in.
