Problems solved by technology

[0002] Existing pressure reducers are mainly divided into diaphragm type and plunger type. Diaphragm type pressure reducer is mainly suitable for low pressure and small flow conditions, and plunger type pressure reducer is suitable for high pressure and large flow conditions; Existing automotive CNG pressure reducers are mainly diaphragm type and plunger type pressure reducer, but diaphragm type pressure reducer cannot achieve high pressure and large flow output, so it is often used in passenger cars, and it is difficult to be used in commercial vehicles system; although the plunger-type pressure reducer has a large flow rate and can be used in high-pressure systems, it also has the disadvantages of low pressure regulation accuracy, high-pressure sealing O-rings are easy to wear, and the service life is not long; so there is an urgent need for a new type of piston. CNG pressure reducer for vehicles with decompression mechanism to solve the above problems
