Spring-loaded check valve for reduction of pressure ripples and noises in piston pump of e.g. antilock braking system in motor vehicle, has closure element movable in flow direction, so as to move closing body and element in flow direction

摘要

The valve has a valve seat arranged in a longitudinal direction to a valve closing body (10), which exhibits a cylindrical guiding section (14) and a dome-shaped sealing section (16). The sealing section is oriented to the valve seat and in the longitudinal direction to the guiding section for alternatively closing and opening an opening that is surrounded by the seat. A closure element (12) is inserted in the body and movable in a flow direction, so that the flow direction from the opening moves the body and the closure element in the flow direction during opening of the valve.
