Suction valve for fuel supply system of internal combustion engine, has valve body for intake process, through which fuel reaches from low pressure area of fuel supply system to pump chamber of high pressure pump

摘要

The suction valve (1) has a valve body (8) for an intake process, through which fuel reaches from a low pressure area of a fuel supply system to a pump chamber (5) of a high pressure pump. Multiple suction holes (10) are formed, which work together with a radial outer portion (13) of the valve body. A spring element (16) is designed as an externally located spring element, which surrounds the outer side of the valve body.
