MECHANISM OF GAS DISTRIBUTION OF INTERNAL COMBUSTION ENGINE PISTON Russian patent published in 2017 - IPC F01L9/04 F02D13/02 

FIELD: engines and pumps.

SUBSTANCE: invention can be used in internal combustion engines (ICE) with the electromagnetic valve mechanism. Mechanism of valve piston internal combustion engine includes a valve (1) inlet valve (2) release of the saddle (3), (4) and guides (6) of valves are installed in the head (7) of the block (8) of the engine cylinder. There is a solenoid actuator with air damper for each valve (1), (2) as an opening and closing electromagnets (9), (10) and (18), (19) placed in housings (11), (20) and anchors electromagnetic drive, designed as pneumatic pistons (12), (21). Pneumatic pistons (12), (21) separate the housing (11) or the housing (22) with electromagnets into upper and lower chambers (13) and (14) or (22), (23). In each of the chambers (13), (14), (22), (23) the window is made (15), (16), (24), (25) which connects the chamber to the atmosphere. Pneumatic piston diameter (12) or (21) is made of 20-30% larger than the average diameter of the landing seat (3) or (4) of the respective valve (1) or (2). The upper chamber (22) of the electromagnetic actuator discharge valve (2) is connected to the cylinder (8) of the engine via a solenoid valve (26) and the pipeline (27) with a cooling jacket (28). An electromagnetic valve drive (1) is provided with inlet solenoid valve (27) which is connected to the window (16) of the lower chamber (14).

EFFECT: unloading solenoid actuator from the action of the gas forces.
