ABSTRACT:
A fluid displacement rotary machine is disclosed, more specifically a rotating piston compressor enclosed in a casing formed with a vent through which may freely enter the gas or vapor to be compressed. Radial cylinders are part of a rotor rotatably supported by a shaft co-axial with the rotor. The rotor is power-driven. The piston connecting rods rotate about a stud fixed to the casing and eccentric to the rotor. Each cylinder head includes a scoop rotating therewith and adapted to channel the gas or vapor into the cylinder head; and further includes a delivery pipe connected to a bore formed in the rotor supporting shaft which extends externally of one casing end wall. The cylinders and the pistons rotate in respective annular paths and yet the pistons make a reciprocating movement within their cylinders because of the eccentric mounting of the stud relative to the rotor axis.
