Check valve, in particular for a high-pressure fuel pump, and pump with check valve

摘要

A check valve, in particular for a high-pressure fuel pump, has a valve member (42) which cooperates with a sealing surface (50) provided thereon with a valve seat (46). The valve member (42) is guided in a receptacle (40) at least over part of its longitudinal extent in a guide portion (56) slidably over its outer jacket. The valve member (42) is cup-shaped and has an inner space (43) which flows through at its with its sealing surface (50) from the valve seat (46) lifted valve member (42) of medium. The outer jacket of the guide section (56) of the valve member (42) is connected via at least one passage (66) to the interior (43) of the valve member (42).
