A slant axis rotary piston mechanism including a shaft (42) having an angularly offset eccentric (44) and a housing (10) defining a general spherical chamber (22) journalling the shaft and containing the eccentric. A peripheral, generally sinuous partition (20) is fixed in the housing and extends radially into the chamber towards the eccentric. A rotor (62) is journalled on the eccentric and is of generally spherical exterior configuration (64) and has a peripheral groove (66, 68, 70) extending about and opening to its periphery. Each of the sides (66 and 68) of the groove face a corresponding side (24, 26) of the partition and define therewith at least two working volumes of variable volume. Gears (108, 110) synchronize relative movement between the shaft, the rotor and the housing, and ports (90, 92, 94, 96) provide for ingress and egress of working fluid to the working volumes.
