Coupling device i.e. hinge shaft, for coupling wing low pressure pump with e.g. shaft, of internal-combustion engine for motor vehicle, has shaft provided with set of hinges, where one of hinges is attached to auxiliary component

摘要

The device i.e. hinge shaft (200), has a shaft (202) provided with a set of end-lateral hinges, where the hinges include a set of auxiliary component-lateral complementary internal-profiles retainers (208, 210) with a set of shaft-lateral external-profiled round heads (204, 206). One of the set of hinges is attached to an internal-combustion engine shaft (212) e.g. cam shaft, and the other hinge is attached to an auxiliary component (110) e.g. wing low pressure pump. The round heads exhibit notch profile, polygon profile, external six round profile or external hexagonal profile.
