    摘要: An engine housing includes a rotor housing and a side housing assembly. The rotor housing includes a rotor housing body. The rotor housing body extends about an axis to form a rotor cavity of the engine housing. The rotor housing body extends between and to a first axial end and a second axial end. The side housing assembly includes a side housing body, a side plate, and a seal assembly. The side housing body is disposed at the first axial end. The side plate is disposed axially between the rotor housing body and the side housing body. The side plate includes an inner side, an outer side, and a perimeter edge. The seal assembly includes a support ring and a sealing ring. The support ring is disposed at the perimeter edge and the first axial end. The support ring circumscribes the side plate. The sealing ring extends between and to a first axial sealing ring end and a second axial sealing ring end. The first axial sealing ring end is disposed at the support ring and the outer side.

    摘要: The invention relates to a six-stroke rotary-vane internal combustion engine with hermetically sealed working space comprising a stator with at least one inlet and at least one outlet, a respective hole for at least one spark plug, and working chambers comprising of an air-fuel intake and compression, and of expansion and exhaust of combustion products working chamber; a cylindrical rotor rigidly fastened to a shaft with combustion chambers alternating with vane grooves made in the cylindrical surface and vanes fitted in the vane grooves; side walls; front and rear bearing shields. The whole working space of the engine is bound by parts rigidly and hermetically fastened to the stator. Composite prismatic pieces are placed into end grooves on both sides of the rotor, while the ends of said composite prismatic pieces are pushed by a first spring against the adjacent vanes and one of the longer sides of the composite prismatic pieces is pushed by a second spring against the side walls.

    摘要: The invention relates to a rotary sliding vane machine (1) for fluid processing, comprising a housing (2) with a cavity (4) with a rotor (9). Vanes (12) are arranged in outwardly directed slots (13) in the rotor (9), and relative sliding between the vanes and the rotor provides spaces with variable volumes in the rotational direction. Each vane is supported by hydrostatic slide bearings (20, 20′) on each side of the vane (12). Due to pressure changes of the process fluid, the vane (12) is tilted towards and away from bearing pads (27, 27, 87). The invention causes the bearing pads to adjust their position to the vane (12), and also causes a change of volume of a bearing fluid chamber (21, 21′, 81), which in turn effects a supply of bearing fluid to the slide bearing fluid film.

    摘要: The present invention relates broadly to a flow diverter disposed in a plenum area of a motor cylinder chamber (also referred to as kidney ports). The flow diverter acts as a barrier between a main inlet to the motor and an inlet to the cylinder chamber, and directs air or fluid to vane lifter ports of the motor before the air or fluid flows to the inlet to the cylinder chamber. In addition, the flow diverter can serve to regulate air or fluid flowing into the cylinder chamber to control power of the tool. The flow diverter allows for numerous options of where the main inlet to the motor can be positioned and provides a means of regulating the air or fluid flowing into the cylinder chamber.

    摘要: A six-stroke rotary-vane internal combustion engine includes a stator having working chambers for intake and compression of air-fuel mixture alternating with working chambers for expansion and removing of combustion products, and a cylindrical rotor including longitudinal grooves housing blades. Side walls of all the working chambers are formed by rotating parts of the rotor, the combustion chambers are formed as hemispherical recesses on a cylindrical surface of the rotor, the working chambers of the stator are formed as cylindrical borings with axes parallel to the stator axis and evenly spaced along an inner surface of the stator, each blade consists of separate plates freely displaceable relative to each other, each plate of the blade being made of two parts movable apart in axial direction by a spring, the number of blades is a multiple of the number of the chambers for intake of air-fuel mixture.
