Pressure relief valve for fuel supply system of motor vehicle, has valve body subjected with resetting force and comprising three guiding lips axially rising into inlet channel and radially arranged to center axis of valve body

摘要

The valve (1) has an inlet channel for filling fuel. A valve body (25) is subjected with a resetting force by a tappet (27) and a reset spring (29) for blocking the inlet channel and flow of the fuel through the inlet channel when flow of the fuel exceeds a limit pressure that is sufficient to overcome the resetting force. The valve body comprises three guiding lips (37) axially rising into the inlet channel and radially arranged to a center axis (35) of the valve body, where the lips have a flexible material. The lips stand in an attachment contact with an inner wall of the inlet channel.
