First Claim
Patent Images
1. A plural-stage gas compressor, comprising:
- a frame;
said frame having a throughgoing bore formed therein, and a plurality of separate channels formed therein which open onto said bore and externally onto outer surfaces of said frame;
a camshaft rotatably journalled in said bore;
a piston cylinder in each of said channels; and
a piston in each of said cylinders;
whereinsaid camshaft has a plurality of cams thereon; and
further includingfirst means interposed between said camshaft and said pistons for causing said cams of said camshaft to translate said pistons, cyclically, in a first reciprocable direction;
second means interposed between said cylinders and said camshaft for causing said pistons to translate, cyclically, in a second reciprocable direction;
head plates fixed upon said outer surfaces of said frame in closure of said channels; and
inlet and discharging valving interposed between each of said head plates and said cylinders.

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.
