Abstract

The present invention discloses an explosion-proof cushion pressure-storing valve. A cushion pressure-storing valve body (1) is installed in a cylinder cover of an internal combustion engine. One end of the cushion pressure-storing valve body (1) is provided with a communicating pipe (13) which communicates a combustion chamber (16) with the cushion pressure-storing valve body (1), and the other end of the cushion pressure-storing valve body (1) is provided with a compression nut (2) of a first through hole (4) and an adjusting gasket (3) of a second through hole. A bush (15), a conical packed piston (9), a spring (8) and a seal ring (10) of the conical packed piston (9) are arranged at the compression nut (2). The compression nut (2) is provided with an adjusting bolt (5) which is corresponding with the conical packed piston (9). The cushion pressure-storing valve body (1) is provided with a pressure storing chamber (11) and is also provided with a third through hole (12) which communicates the pressure storing chamber (11) with the combustion chamber (16). The conical packed piston (9) cuts off the third through hole (12) when being arranged at the lowest bottom. For the internal combustion engine with high compression ratio, the explosion-proof cushion pressure-storing valve can avoid the damage caused by over high combustion pressure and can improve the dynamic property, the economical efficiency and working stability and reliability.

Description

technical field [0001] The invention relates to an explosion-proof pressure storage valve, in particular to an explosion-proof buffer pressure storage valve for an internal combustion engine. Background technique [0002] Increasing the compression ratio can greatly enhance and improve gasoline engines in terms of power and economy, but there are huge obstacles. This is but when the gasoline engine works under the condition of high compression ratio and fast fuel injection, it will inevitably bring about excessive combustion pressure and knocking of the engine, which not only fails to improve power and economy, but also backfires, causing the combustion process to deteriorate , and impair the smoothness and reliability of the engine. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an explosion-proof buffer pressure storage valve that can avoid excessive combustion pressure when using a high compression ratio, wi...
