A family of sliding vane rotary power devices provides an internal combustion engine, a pump, a compressor, a fluid-driven motor, an expander device, a fluid-driven pump, and a compressor or a throttling device. All of these devices have an improved method of vane actuation comprising a freely sliding element partially enclosed by a medially extended outer vane portion and partly enclosed at its ends by a mirror-image encircling cam groove formed in a circumferentially-split external housing. As the rotor turns, the sliding elements engage the encircling extended vane portion and the mirror-image cam grooves cause the vanes to reciprocate radially in respective rotor slots while the outer vane tips follow the wall contour of the rotor with a minimal clearance so that the cavities rotate with the rotor and expand and contract as the rotor turns. Various devices in the family of devices differ both in the configuration of an internal stator member about which the rotor assembly turns and in the disposition of ports.
