The compressor comprises four stages of compression. It has four compression chambers within four, separate compartments removably bolted to a central, supporting, gear housing. In the compression chambers are rotary (rolling) pistons. A pair of parallel, gear-driven shafts journalled in the housing have eccentric pins on ends thereof. The pins intrude into the chambers and rotatably carry the rotary pistons thereon. Conduits traverse the compartments to inject water into the chambers for cooling, sealing, and lubrication of the rotary pistons. Too, the compartments conduct compressed gas therethrough from the compression chambers, and conduct coolant therethrough as well to heat exchange with the compressed gas product.
