ABSTRACT:
The compressor, of the reciprocating-piston type is actuated by a camshaft confined in a small, compact frame. Cams translate cross-heads which are slidably guided within the frame, and which are threadedly coupled to depending stubs of the pistons. A bolted-on head plate confines valving components atop cylinders set within the frame, and the head plate has passageways formed internally to conduct the gas to and from successive stages of compression.
