A rotary apparatus includes a stationary stator having an internal cylindric al chamber. A rotor is rotatably mounted in the chamber. There are cam-like annular surfac es on the stator to each side of the rotor. A plurality of vane assemblies are slidably mount ed on the rotor. The vane assemblies each have two outer ends. These slidingly engage the cam - like annular surfaces, whereby gases between the vane assemblies are compressed and expan d between the cam-like surfaces and the rotor as the rotor and vanes rotate relative t o the stator. Preferably each of the vane assemblies has two separate components, each out er end being on one of the components. The apparatus has a conduit for conducting compressed gases between the two components of each of the vane assemblies and thereby biasin g each of the components towards one of the cam-like annular surfaces. Preferably there is an intake system for intaking gases between the vane assemblies and between the cam-li ke surfaces and the rotor and an exhaust systems for conducting exhaust gases away from the spaces. Each of the intake and exhaust systems preferably includes a reed valve. The re may be a rotatable annular housing within the stator between the stator and the rotor . The components of the vane assemblies engage the housing, the housing rotating with the rot or and the vane assemblies.
