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.

Abstract: The Compressor comprises three stages of compression, having three cylinders, each of the latter having a piston reciprocable therein. Two of the pistons are in-line along a common axis, and the cylinders therefor are in confronting relationship. The third cylinder lies along an axis which traverses the two-piston axis. All three pistons are reciprocated by two connecting rods, in that the in-line pistons are joined by tie rods. Both connecting rods are coupled to the single crank of a crankshaft which is journalled in a crankcase, and all three cylinders are removably bolted to the crankcase.

Abstract: The seal, for use especially in non-lubricated, high-pressure, as compressors, in a one-piece, continuous sleeve which envelopes a reciprocable piston for sealing against the piston, or against the cylinder in which the piston translates. One end of the sleeve effects the sealing engagement, and the other end is spring-loaded to maintain the engagement. During operation of the compressor, or the like, it is the high-pressure gas which urges the seal into sealing engagement.

Abstract: The invention, a high-pressure, reciprocating, gas compressor, employs labyrinths to create gas sealing, annular, air dams between the piston and cylinder bore, and piston rod and an aperture in an end wall or closure of the cylinder through which the rod translates, and active magnetic bearings to maintain the piston and rod at their centroids, equally and minutely spaced, fully thereabout, within the bore and aperture. Too, the drive mechanism, a scotch yoke arrangement, has further, active magnetic bearings, to centralize a drive shaft in its housing, and to effect a non-contacting travel of the drive shaft's offset crank, which translates the piston rod, within the yoke.

Abstract: The compressor has a crankcase which is horizontally separable and has piston cylinders removably coupled to opposite ends thereof. The crankcase confines a pair of tie-rod-joined crossheads therein, and guides control reciprocation of the crossheads in horizontal and vertical planes. Inlet and discharge valves are all accessibly fastened to the cylinders, and oil buffers and gas seals set about piston rods inhibit insinuation of oil into the cylinders, and gas into the crankcase.

Abstract: The Compressor is small, compact and lightweight in that it is formed of the barest essentials. It has a pair of in-line cylinders, with pistons reciprocatable therein, and the crankshaft, having only one crank, is drivingly coupled to one of the pistons. The other piston is fastened to the crank-driven piston, in spaced-apart disposition, for a common reciprocation of the two. One of the cylinders serves as the crankcase.

Abstract: 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.

Abstract: A seal of annular configuration sealingly engaged with an annular surface of an element, to inhibit a communication thereacross of low- and high-pressure environments of the surface, and either one, or a pair of annular support rings engaging the seal. The seal and rings have interfacing and tapered or inclined surfaces and, consequently, the seal is restrained against (a) an unwarranted movement toward the surface being sealed, thereby to prevent its unwarranted extrusion, and (b) heavy radial gas force in that the gas forces act axially and radially on the support rings.

Abstract: The seal, for use especially in non-lubricated, high-pressure, as compressors, in a one-piece, continuous sleeve which envelopes a reciprocable piston for sealing against the piston, or against the cylinder in which the piston translates. One end of the sleeve effects the sealing engagement, and the other end is spring-loaded to maintain the engagement. During operation of the compressor, or the like, it is the high-pressure gas which urges the seal into sealing engagement.
