PROCESS AND DEVICE IMPROVING THE SLIDING OF ALTERNATING PISTONS OF THERMAL ENGINES

摘要

In a process for improving the sliding of alternating pistons of thermal engines while counteracting the tilting movement of said pistons, a pressure gradient is generated by the action of vibrating elastic means (1, 1a) resistant to the thermal and chemical stresses produced by the explosion, and by the usual infiltration of the driving gases into the piston groove, said means being mounted behind the piston ring. The pressure gradient results in the formation of a permanent pressurized toric seal during operation of the engine.
