VANE-TYPE ROTARY INTERNAL COMBUSTION ENGINE (VARIANTS), A BLADE-SWINGING MECHANISM, UNIT OF BLADE SEALING ELEMENTS AND A BEARING SUPPORT FOR SAID BLADE SWINGING MECHANISM

WIPO Patent Application WO/2004/106712

A1

The invention relates to the power engineering industry and can be used for motor engineering for transport means and stationary power plants. The aim of said invention is to increase the power, reliability, operation economy and operating and ecological characteristics of the engines. The sense of the invention lies in that the inventive vane-type rotary engine comprises two irregularly rotatable blade units arranged inside the cylindrical part of a body and is provided with a gas mixture and a gas channel which connecting a container by means an output window embodied in said body to the end of the expansion area of a working chamber. The bearing gear of the blade swinging mechanism is movably arranged and connected to with a unit for adjusting the fixing angle thereof with respect to the body on a plane perpendicular to an output shaft axis. In the unit of longitudinal seal elements, the spaces between the internal surface of the slots of the blade are filled with elastoplastic material. In the unit of radial seal elements, the contacting radial sides of a ring and a lateral lid are embodied in the form of a cone. The distance between the conical side surface and the internal end surface of the lateral lid is embodied in such a way that it reduces towards to the internal cylindrical surface of the body. In the unit of bearing supports of the blade swinging mechanism, each pocket is connected to a pressure oil supply unit by means of a central channel which is embodied in a central pin and provided with a return valve and to a closed system of hydraulic channels by means a peripherial channel embodied in said pin. The pockets arranged on the same side from the plane of the longitudinal seal elements with respect to the direction of rotation of the blades are connected to the closed channel system, the pockets arranged on the other side of said plane are connected to another closed system of channels.
