A rotary piston machine is shown that is operable with a compressible fluid; such as a rotary pump, compressor or engine construction. There is a housing having an inner and an outer ring member that are rotatably mounted on a common axis. The outer ring has at least two diametrically opposed inwardly directed segmental pistons. The inner ring has at least two diametrically opposed outwardly directed segmental pistons so as to define working chambers therebetween. An oscillating coupling means is positioned within the inner ring and flexibly joined to both ring members as well as rotating around a fixed offset crankpin to cause the inner and outer pistons to change position with relation to each other as the two ring members revolve around their common axis so as to create compression and expansion strokes.

A rotary piston machine operable with a compressible fluid and comprising in combination: a. a housing having walls forming a circular bore, b. an outer ring member rotatably mounted within the housing about a central axis and including at least two integral diametrically opposed inwardly directed s

A rotary piston machine operable with a compressible fluid and comprising in combination: a. a housing having walls forming a circular bore, b. an outer ring member rotatably mounted within the housing about a central axis and including at least two integral diametrically opposed inwardly directed segmental pistons, c. a concentric inner ring member positioned within and carried by the said outer ring member and including at least two integral diametrically opposed outwardly directed segmental pistons which are interposed between the said outer pistons and define with the outer ring pistons energy chambers therebetween, d. and an oscillating coupling means positioned within the inner ring member and rotating around a fixed offset crankpin to cause the inner ring member to accelerate with respect to the outer ring during a first one-half revolution of the coupling means to create a compression stroke on its forward side and to decelerate with respect to the outer ring during the second one-half revolution of the coupling means to create a compression stroke on its rearward side.
