INTERNAL COMBUSTION ENGINE Russian patent published in 1999 - IPC

Abstract RU 2133349 C1

FIELD: mechanical engineering; designing of small-size internal combustion engines for agriculture, engine-generator sets and vehicles. SUBSTANCE: engine has at least one cylinder, crankshaft, crankcase with oil bath, oil pump arranged in crankcase bore and connected with suction and delivery pipelines. Engine has oil flow change-over system made in form of cylindrical spacer with shaped slots and installed between oil pump cover and end face surface of bore. Oil pump suction and delivery holes are placed in communication through spacer slots with like pipelines when crank-shaft is rotated in one direction. When direction of crankshaft is change into opposite one, suction and delivery holes of oil pump are placed in communication with unlike pipelines through slots of spacer. EFFECT: simplified design of engine. 5 dwg
