Abstract
A non-contact rotary vane gas expanding apparatus functions to convert controlled expansion of gas under pressure to rotary motive power. The gas expanding apparatus includes a stator housing, a rotor supported in the stator housing to undergo rotation relative thereto with the rotor having an output member thereon, a plurality of vanes disposed in a plurality of radial slots defined in the rotor and being circumferentially spaced from one another and radially reciprocable relative to the rotor such that outer tip portions of the vanes are maintained in non-contacting substantially sealed relation with the stator housing, a plurality of gas receiving pockets defined in the rotor adjacent to trailing sides of the radial slots and of the outer tip portions of the vanes with reference to the direction of rotation of the rotor relative to the stator housing, and a plurality of formations defined in the stator housing to effectuate the transfer of gas under pressure through the stator housing to successive ones of the gas receiving pockets to enable the expansion of the pressurized gas therein to cause rotation of the rotor and the output member therewith. The non-contact rotary vane ga…
