Abstract
The assembly, designed for use in combination with a straight-cylinder, gas-compression chamber, has a center bolt which is threaded at opposite ends thereof to receive a pair of valve sets. Each of the latter has a ported valve seat, valve guard, and ported valve plate. The guard is set about the bolt, and against a shoulder formed on the bolt therefor. The seat is centrally threaded, to engage one of the threaded ends of the bolt, and it and the guard confine the valve plate therebetween. In that one of the valve sets is turned 180.degree. from the other, i.e., the two guards being in confrontation, and the two seats remotely disposed, vis-a-vis, the one valve set is open to fluid flow, while the other is closed, as the assembly is reciprocated in such a straight-cylinder, chamber. Identical valve sets, on different, short bolts set in end closures of such a chamber, serve as gas inlet valves, while the reciprocable assembly carries the discharge valves. The invention obviates any need for pistons, per se as, according to a feature of the invention, the valve sets carry replaceable sealing (viz., piston rings).
