Automotive fluid pump arrangement with vibration decoupling support
The granted patent US12038021B2 describes an innovative automotive fluid pump arrangement designed to enhance the mounting and stability of the pump unit within a vehicle. The arrangement includes a pump unit featuring an axial pump unit stop surface and a mounting device that supports and secures the pump unit. The mounting device consists of a ring-shaped support part that radially encloses the pump unit, providing vibration decoupling. A key feature is the tensioned friction-enhancing longitudinal lip ring, which surrounds the pump unit and is designed to frictionally lock it in place during assembly. Notably, the inside perimeter of this lip ring is at least 5% smaller than the outside perimeter of the pump unit's mounting section prior to assembly, ensuring a secure fit.
Further claims detail additional aspects of the pump arrangement, including the conical shape of the lip ring before assembly, its integral connection to the support part, and the design of the mounting part. The arrangement also includes features such as a tangential pump outlet and castellated surfaces for anti-rotation protection. The claims emphasize the circular design of both the support part and the pump unit mounting section, enhancing compatibility and stability. Overall, this patent presents a comprehensive solution for improving the performance and reliability of automotive fluid pumps through innovative mounting techniques and structural design.
