n: in a reciprocating compressor, the volume between the top of the piston and the cylinder head with the piston at the top of its stroke.

n: a device that raises the pressure of a compressible fluid such as air or gas. Compressors create a pressure differential to move or compress a vapour or a gas, consuming power in the process. They may be positive-displacement compressors or nonpositive-displacement compressors. See centrifugal compressor;jet compressor;reciprocating compressor.

a type of pump that increases the pressure of gas. Commonly used as a production rate increaser by increasing the gas pressure delivered from low pressure gas wells to enter the pipe line. The intake into the compressor lowers the wellhead pressure creati

n: see reciprocating compressor.

n: a type of compressor that has pistons moving back and forth in cylinders, suction valves, and discharge valves, i.e., a positivedisplacement compressor. Reciprocating compressors are used extensively in the transmission of natural gas through pipelines.
