MECHANISM OF REVERSAL OF ROTOR ENGINE Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: mechanism of reversal of rotor engine has hollow body, shaft with rotor, separating spring-loaded shut-off dampers, means of gas exchange and delivery of working medium, control lever kinematically coupled to specified means. Mechanism is additionally provided with stoppers with axles. Shut-off dampers are manufactured intercoupled and have bevels directed to side opposite to adjacent shut-off damper. Each shut-off damper has cylindrical socket with bevel directed towards spring. Control lever is fork with two branches with oval holes accommodating axles of stoppers. Stoppers are mounted in holes of body for interaction with cylindrical sockets of shut-off dampers and their bevels. Means of gas exchange are built in the form of poppet valves kinematically coupled to holes of control lever. Means of delivery of working medium are produced in the form of controlled injectors. EFFECT: simplified design, enhanced reliability and efficiency. 4 dwg
