Abstract

The invention discloses a combined pressure regulating piston based on an elastic silencing and impact-resistant cylinder gasket and relates to the combined pressure regulating piston. The elastic silencing and impact-resistant cylinder gasket is arranged between a cylinder cover and a cylinder body and consists of an upper sealing gasket, a cylinder gasket main body and a lower sealing gasket which are connected in sequence; the cylinder gasket main body comprises an elastic steel plate, circular holes, elastic steel claws, mounting holes and water channel holes; the circular holes are formed in the middle of the elastic steel plate; the elastic steel claws are uniformly and symmetrically arranged at the periphery of each circular hole; the mounting holes and the water channel holes are formed outside the circular holes. The combined pressure regulating piston highly affects the heat efficiency of the torque of an engine, the heat efficiency of a gasoline engine can be improved by about 7 percent, and the heat efficiency of a diesel engine can be improved by about 5 percent; under the condition that the elastic force of a pressure regulating spring can be regulated, all the advantages of the combined pressure regulating piston can be played at the same time, and playing of the roles of external additional mechanisms of the engine such as a turbo charging mechanism and a stratified combustion mechanism is not affected.
