TWO-STROKE INTERNAL COMBUSTION ENGINE Russian patent published in 1995 - IPC

FIELD: engine engineering. SUBSTANCE: when step piston moves from the top dead center to the bottom dead center, air is compressed in the delivery cylinder. The compressed air opens the inlet valve made in the bottom of the hollow of the baffle and fils internal space of the piston. When a projection provided on the cover of the delivery cylinder enters the hollow of the piston baffle, supplying of the compressed air stops and further compressing of the air begins in the delivery cylinder. When pressure, which is required for consumer, is achieved the outlet valve made in the cover is open and compressed air enters a receiver. The outlet valve is adjusted for pressure which is more higher than blowing pressure. For this reason, the valve do not open at blowing pressure. This excludes lowering of quality of blowing of the working cylinder. EFFECT: enhanced efficiency. 2 cl, 2 dwg
