| titleOfInvention | Engine with piston inner one-way valve |
| abstract | An engine with a piston inner check valve is provided with a cavity (41) communicated with the interior of each wedge, and the space of the cavity is arranged between the piston surface of an engine piston (17) and the layer surface of the upper part of a piston pin hole at the piston pin placing end of the engine piston (17) to form a buffer gap and a noise reduction space; each wedge is provided with at least one escape hole (42) so as to be communicated with the plurality of through holes (32) and the oval inlet (34) through the inside of each wedge to form the cavity (41), a plurality of hexagonally-pyramidal built-in wedges (45) are arranged in the lower layer of the cavity (41), hexagonal through holes (44) are arranged at the small ends of the hexagonally-pyramidal built-in wedges, oval outlets (43) are arranged at the large ends of the hexagonally-pyramidal built-in wedges, and an inner filter screen (46) for bulking glass fibers is arranged between the lower layer and the upper layer of the cavity (41) so as to achieve secondary buffering and noise reduction; an engine with a piston internal check valve, the piston internal check valve is connected with the cavity (41) at the inlet end and connected with the auxiliary air port (28) at the outlet end. |
