ABSTRACT:
A fluid operable rotary piston device having a housing with gas inlet and tlet means and a hollow cylinder rotatable therein having gas inlet and gas outlet ports which communicate with the gas inlet and outlet means during rotation of the cylinder. A rotary piston is rotatable on an eccentric axis inside the cylinder and the cylinder and piston have interengageable means forming contact free working chambers. Axial sealing strips are mounted on one of the piston and cylinder and form contact free sealing gaps between adjacent working chambers. The cylinder rotates in the housing in contact free relation therewith and a transmission connects the piston and cylinder for rotation at respective speeds.
