Rückschlagventil für eine Kraftstoffpumpe

摘要

A check valve (10) for a fuel pump (12) of a vehicle includes a valve housing (26) adapted to be disposed in an outlet member (20) of the fuel pump (12) and a valve seat (36) formed on the valve housing (26). The check valve (10) also includes a valve member (38) disposed in the valve housing (26) and having a closed position to engage the valve seat (36) to prevent fuel from flowing through the outlet member (20) and an open position to allow fuel to flow through the outlet member (20). The valve housing (26) has a vortex abating geometry (48) located near the valve seat (36) to add turbulence to fluid flow past the valve seat (36) when the valve member (38) is in the open position.
