| description | A fuel pump includes a fuel pump housing with a pumping chamber and an inlet valve bore which extends along an inlet valve bore axis. The inlet valve bore is stepped such that the inlet valve bore includes a shoulder which is traverse to the inlet valve bore axis. A pumping plunger reciprocates within a plunger bore along a plunger bore axis such that an intake stroke of the pumping plunger increases volume of the pumping chamber and a compression stroke of the pumping plunger decreases volume of the pumping chamber. An inlet valve assembly includes a valve seat with a valve seat flow passage extending therethrough, the valve seat abuts the shoulder and is urged toward the shoulder by pressure within the pumping chamber during the compression stroke. The inlet valve assembly also includes a valve member which is moveable between an unseated position and a seated position. |
