  Gas compressor having a variable-volume clearance pocket, and means for varying a clearance pocket in a gas compressor ...
This invention pertains to gas compressors, especially those of the reciprocating piston type, and in particular to a gas compressor of the aforesaid type which has a variable-volume clearance pocket, and to means for varying a clearance pocket in such a gas compressor.
The clearance volume or clearance pocket of gas compressors is normally varied, to alter the capacity of the compressor, by extraneous devices and/or components attached to the cylinder head, such devices or components being designed to satisfy that very function: vary the volume or pocket obtaining between the piston and the cylinder head.
As shown in the figures, the compressor 10, according to an embodiment of the invention, comprises a single, straight cylinder 12 having a longitudinal axis 14 and a circumferential wall 16.

  Gas compressor Summary
A gas compressor is a mechanical device that increases the pressure of a gas by reducing its volume.
As gases are compressible, the compressor also reduces the volume of a gas, whereas the main result of a pump raising the pressure of a liquid is to allow the liquid to be transported elsewhere.
Centrifugal compressors — a vaned rotating disk or impeller in a shaped housing forces the gas to the rim of impeller increasing the velocity of the gas.

Gaseous helium is used, as already mentioned, in aerial navigation, as a protective gas for diverse processes (chemistry, metallurgy, semiconductor production), as search gas for leakage measurements (among others for testing air conditioning plants in the automobile industry), during diving as a diving gas mixture as well as an inert coolant for special machine applications.
When full, the high pressure gas compressors are started via a level control sensor; they take in the helium gas, compress it to 300 bar and store it in high pressure containers.
Besides the required airtightness, the helium compressors have to be better cooled due to the higher heat capacity compared to air, and also require a higher quality standard of the individual components (e.g.

  Science Fair Projects - Gas compressor
A gas compressor is a mechanical device that increases the pressure of a gas by reducing its volume.
Compressors are loosely related to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe.
As gases are compressible, the compressor also reduces the volume of a gas, whereas the main result of a pump raising the pressure of a liquid is to allow the liquid to be transported elsewhere.

Since a turbocharger is an exhaust driven compressor, the engine must be producing a sufficient quantity of exhaust gases to drive the turbocharger, which may only occur once the engine gets to a high rpm.
Compressor has several meanings: A gas compressor is a mechanical device that takes in a gas and increases its pressure by squeezing a volume of it into a smaller volume.
Centrifugal superchargers operate in the same fashion as a turbo; however, the energy to spin the compressor is taken from the rotating output energy of the engine's crankshaft as opposed to exhaust gas.

The compressed form of the gas is not so compact but is marginally useable for local vehicular travel.
As more gas is produced, it is stored in the gasometer and the floating tank rises to accommodate the increased volume.
A constant pressure is mainted throughout by the consumption of gas which enables the floating tanks to float lower.

For gas turbine driven centrifugal compressors, the prime mover efficiency is moderate to high depending on cycle efficiency and the compression efficiency can range from low to high depending on the compressor wheel design and the operating pressure range.
For direct connected motor driven reciprocating compressors, the prime mover thermal efficiency is very high based on electric power generation and electric transmission system efficiencies, and the compression efficiencies are similar to their gas engine driven counterparts.
The scope of work for a motor driven compressor is much less, beginning with the physical size of the property needed to establish a sound buffer area and extending to the size of the building, the design of the foundations and all the other structural elements.

The transportation system for natural gas consists of a complex network of pipelines, designed to quickly and efficiently transport natural gas from its origin, to areas of high natural gas demand.
To ensure that the natural gas flowing through any one pipeline remains pressurized, compression of this natural gas is required periodically along the pipe.
This is accomplished by compressor stations, usually placed at 40 to 100 mile intervals along the pipeline.
