ABSTRACT:
A piston compressor. First and second manifold plates are joined together with their inner surfaces in fluid-tight abutment. First and second cylinder housings are affixed to the outer surfaces of the first and second manifold plates, respectively, in fluid tight fashion and oriented at 90.degree. with respect to each other. Each cylinder housing contains first and second opposed, fixed piston rod/piston head assemblies, each extending axially from an end of its respective cylinder housing. Each cylinder housing contains an elongated sleeve having an axial bore at each end receiving one of the piston heads in sealing engagement and defining therewith a compression chamber. A crank comprising a crank element and oppositely directed crank pins having its crank element located in a central hole in the manifold plates and its crank pins each mounted in bearings in a central transverse hole in one of the sleeves. As the crank is rotated the crank element has an essentric motion so that each crank pin rotates about its own axis and simultaneously reciprocates rectalinearly causing its respective sleeve to reciprocate in its respective cylinder housing. The crank is driven by connection of one of its crank pins to an input shaft through a power transfer assembly. Ambient or low pressure fluid is introduced into each compression chamber by manifold passages and at least one one-way valve in the piston head. Pressurized fluid exists each compression chamber through a one-way valve and passages formed in the piston rod/piston head and in the manifold plates.
