ABSTRACT:
A fuel injection pump includes a rotary distributor having a bore housing a pair of pumping plungers which are actuated by a cam. The distributor member also carries a valve member which is actuated by a cam. The valve member has a groove which can spill fuel to a drain when the valve member is moved to an operative position. In addition the valve member restricts the backflow of fuel from an outlet when fuel is spilled from the bore.
