GRECHKIN ROTARY ENGINE

摘要

The invention relates to the field of engine design, in particular to rotary internal combustion engines, and solves the problem of simplifying the design of an engine and increasing the reliability and operating efficiency thereof. The problem of interest is solved in that in a rotary engine comprising a hollow housing with an inside cylindrical surface, an intake port, an exhaust port and an ignition source, a combustion chamber, a shaft situated on the axis of the inside cylindrical surface of the housing, a cylindrical rotor, and also a spring-loaded separating valve that is in contact with the outside cylindrical surface of the rotor across the entire width of the rotor, the cylindrical rotor is mounted eccentrically on the engine shaft such that it is able to contact with the inside cylindrical surface of the housing, wherein the cylindrical surface of the rotor has a depression situated in proximity to the line of contact of the rotor with the housing, on the side of the line opposite to the direction of rotation of the rotor. In the proposed engine, the depression on the surface of the rotor can be inclined so that the deepest part thereof is located towards the line of contact; at the other end, the incline merges smoothly with the outside surface of the rotor. Furthermore, the rotor can be equipped with a wear-resistant insert situated along the line of contact of the rotor with the inside cylindrical surface of the housing, and the spring-loaded separating valve can be disposed on a pivoted lever.
