Automotive fluid pump arrangement with vibration decoupling support
The 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 features a pump unit with an axial stop surface and a mounting device that includes a ring-shaped support part. This support part is engineered to radially enclose and support the pump unit while providing vibration decoupling. A key component of this design is a tensioned friction-enhancing longitudinal lip ring, which is configured to gaplessly surround the pump unit, ensuring a secure frictional lock in the axial dismounting direction. 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, facilitating a tight fit.
Further claims within the patent elaborate on the structural features of the pump arrangement. The tensioned lip ring can be conical and may be an integral part of the support part. Additionally, the design includes a connection zone that extends axially in the mounting direction of the pump unit. The pump unit is also equipped with an electrical plug socket extending from its front-end surface, enhancing its functionality. The mounting part is designed to attach to the vehicle's structure and is also an integral component of the support part. The arrangement ensures that both the support part and the pump unit mounting section are circular, with features such as castellated surfaces for anti-rotation protection and a tangential pump outlet, further contributing to the overall efficiency and reliability of the automotive fluid pump system.
