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

A fluid compressor comprising a housing defining an internal bore and an outlet registering with the bore;

• two spaced heads disposed at the respective ends of the bore and adapted to receive the fluid;
• a first series of inlet valve assemblies disposed in one of the heads and radially spaced from the central axis of the bore for permitting the flow of the fluid from the one head and into the bore and for preventing the flow of the fluid from the bore to the one head;
• a second series of inlet valve assemblies disposed in the other head and angularly spaced around the central axis of the bore for permitting the flow of the fluid from the other head, and into the bore and for preventing the flow of the fluid from the bore to the other head;
• and two spaced piston/valve units mounted in the bore for reciprocal movement and adapted to move in one direction to draw the fluid through one series of valve assemblies and into the bore while compressing the fluid in the bore from the other series of valve assemblies, and to move in the opposite direction to draw the fluid through the other series of valve assemblies and into the bore while compressing the fluid in the bore from the one series of valve assemblies.
