Patent ID: 8662863

Claim:
A gas compressor system adapted for operation by an external power source, the compressor system comprising: a horizontally opposed engine block of an internal combustion engine having a plurality of cylinders disposed therein, wherein a first bank of at least two cylinders of the plurality of cylinders is disposed on a first side of the engine block, the at least two cylinders being disposed in a side-by-side relationship; a crankshaft rotatably disposed in the engine block and exposed therefrom for powered rotation by an external power source; a piston reciprocally disposed in each of the plurality of cylinders and connected to the crankshaft for reciprocal motion therein in response to the rotation of the crankshaft by the external power source; and a modified head assembly mounted to the engine block, the modified head assembly adapted to afford controlled flow of gas therethrough for the compression thereof and comprising: a suction port on a first surface of the modified head assembly for receipt of gas to be compressed; a discharge port on a second surface of the modified head assembly for discharge of compressed gas; at least two suction valve receiving bores, each suction valve receiving bore having a suction valve disposed therein, each suction valve being a one-way valve oriented to facilitate gas flow from the suction port to one of the cylinders of the plurality of cylinders; and at least two discharge valve receiving bores, each discharge valve receiving bore having a discharge valve disposed therein, each discharge valve being a one-way valve oriented to facilitate gas flow from one of the cylinders of the plurality of cylinders to the discharge port, and each of the discharge valves comprises a position at a lower level than at least one of the cylinders.
