    摘要： An outlet valve assembly for a common rail fuel pump for an internal combustion engine, comprising a valve member (18) provided with a frusto-conical surface which is engageable with a valve seating (16) to control fuel flow between a high pressure pump volume of the fuel pump and a common rail located downstream of the pump volume, and an outlet flow passage (36, 32, 34) for fuel through which fuel flows to the common rail when the valve member (18) is lifted from the valve seating (16). A valve housing (12) is provided within a valve housing bore (14), the valve member (18) including a guide portion (18a) which cooperates with the valve housing bore (14) so as to guide movement of the valve member (18), in use. The valve seating (16) is defined by the valve bore housing (14) and is of frusto-conical form.
