This application discloses a one-way valve for automotive piping systems, relating to the field of one-way valve technology. The application includes a valve housing with an annular groove in its inner middle section. An abutment ring is fixedly connected inside the valve housing. A mounting platform is fixedly connected inside the valve housing, and a compression groove is formed inside the mounting platform. An elastic airbag is fixedly connected inside the compression groove. A T-shaped slide rod is fixedly connected to one end of the elastic airbag. An insertion hole adapted to the T-shaped slide rod is formed at one end of the mounting platform. One end of the T-shaped slide rod passes through the insertion hole and is fixedly connected to a valve plug adapted to the abutment ring. This application utilizes the elastic airbag and internal gas pressure to assist a spring in pushing the valve plug against the abutment ring, thereby creating contact. Simultaneously, the elasticity of the airbag absorbs some of the impact and vibration experienced by the valve housing, mitigating sealing problems caused by vibration. Furthermore, when the spring experiences metal fatigue, the elastic airbag can serve as a backup mechanism to ensure the system continues to operate normally, effectively improving the reliability of the device.

This invention discloses a hybrid power transmission shifting system based on a parallel shaft structure, solving the technical problem that excessively large transmission dimensions lead to difficulties in hybrid power transmission structural design, or insufficient structural applicability and reliability. The invention includes an actuator and a shift fork assembly housed within the transmission housing. The actuator includes a main gearbox shifting module, a secondary gearbox shifting module, and a gear selection module. The output mechanisms of the main and secondary gearbox shifting modules move in directions parallel to the axial direction of the shift fork shaft; the gear selection output mechanism moves in a direction perpendicular to the axial direction of the shift fork shaft. The top of the shift fork assembly has shift fork selection slots, and each shift fork selection slot is staggered axially. The gear selection block has clearance fits with the shift paddle and the gear selection output mechanism, respectively; the shift block has clearance fits with the main gearbox shift output mechanism. This invention arranges the main gearbox shifting module, the secondary gearbox shifting module, and the shift fork shaft in parallel, effectively shortening the axial length of the shifting system.
