The patent application (Publication Number: US20240003363A1) discloses an innovative automotive fluid pump arrangement designed to improve the mounting and support of the pump unit. The arrangement includes a mounting device with a ring-shaped support part that radially encloses and provides vibration-decoupling for the pump unit. This support part features an axial stop surface that cooperates with a corresponding stop surface on the pump unit to axially secure the pump unit in place. Additionally, a tensioned friction enhancing longitudinal lip ring surrounds the pump unit to frictionally lock it in place, preventing axial dismounting.

Furthermore, the tensioned friction enhancing longitudinal lip ring is designed to have an inside perimeter smaller than the outside perimeter of the pump unit mounting section before assembly, ensuring a secure fit. The arrangement also includes features such as castellated stop surfaces for anti-rotation protection, a conical shape for the friction enhancing ring before assembly, and an electrical plug socket extending from the pump unit's front-end surface. Overall, this automotive fluid pump arrangement aims to provide a secure, vibration-decoupled, and easily mountable solution for automotive fluid pumping systems, enhancing efficiency and reliability in operation.
