A gas compressor and method according to which a plurality of inlet valve assemblies are angularly spaced around a bore. A piston reciprocates in the bore to draw the fluid from the valve assemblies during movement of the piston unit in one direction and compress the fluid during movement of the piston unit in the other direction and the valve assemblies prevent fluid flow from the bore to the valve assemblies during the movement of the piston in the other direction. A discharge valve is associated with the piston to permit the discharge of the compressed fluid from the bore.

Gas compressor comprising a double acting piston, an elongate chamber, multiple inlets mounted within heads on both sides of the chamber, and one central outlet

In a rotary gas compressor which has a compression housing, in which the gas compressing elements are operatively confined, a shaft and bearing housing is provided. The latter housing is removably coupled to an end of the compression housing, and supports therein the rotary shaft and the bearings therefor. The bearings are located in a portion of the shaft and bearing housing which is outboard or external of the compression housing. A coolant chamber is set abut the shaft and bearing housing whereat the bearings are located. The latter housing further has apertures formed therein to visually expose the shaft, as well as for discharging therethrough any leaking lubricant.
