A rotary motor with a pair of abutments that move relative to a rotor through the rotation of gears operatively connected to both the abutments and the rotor. The abutments and rotor are located within a housing such that the inner cavity of the housing is divided into four chambers. The rotor has a pair of blade sections that are in constant contact with the motor housing, so that the chambers are always sealed from each other. Also connected to the housing are a pair of intake ports and a pair of exhaust ports. The rotor rotates within the inner cavity pushing air from the intake ports to the exhaust ports. The abutments are constructed to move in a linear direction, to allow the blade sections to rotate from one chamber to another. The movement of the abutments is synchronous with the rotation of the rotor, so that the abutments are always in contact with the rotor to insure that there is negligible fluid communication between chambers. The abutments are connected to the rotor through a pair of gears that are external to the inner cavity of the housing. The gears are attached to a crankshaft that translates the rotation of the rotor into a linear movement of the abutments. The blade sections of the rotor each have a pair of concave surfaces with an outline which insures that the abutments and rotor are always in contact with each other.
