A diesel engine fuel supply system having an injector pump, a fuel tank, a fuel inlet conduit between the fuel tank and the injector pump and a fuel return conduit between the injector pump and the fuel tank, a venting fuel valve including a valve body, an adapter for mounting the valve body on the injector pump, a fuel inlet on the valve body for receiving the fuel inlet conduit, a fuel outlet on the valve body for transmitting fuel to the injector pump, a vent in the valve body in communication with the atmosphere, a valve spool in the valve body movable to a first position for effecting communication between the fuel inlet and the fuel outlet to supply fuel to the injector pump while preventing venting of the fuel outlet to the atmosphere through the venting means, and the valve spool being movable to a second position for preventing communication between the fuel inlet and the fuel outlet and for effecting communication between the injector pump and the atmosphere to thereby vent the injector pump and prevent flow of fuel through the fuel return conduit to the injector pump when the injector pump is caused to operate, and an endless curvilinear groove in the valve spool for receiving a mating ridge on a key for turning the valve spool between the first and second positions.

In a diesel engine fuel supply system having an injector pump, a fuel tank, a fuel inlet conduit between the fuel tank and the injector pump, and a fuel return conduit between the injector pump and the fuel tank, the improvement comprising a venting fuel valve including a valve body, mounting means
In a diesel engine fuel supply system having an injector pump, a fuel tank, a fuel inlet conduit between the fuel tank and the injector pump, and a fuel return conduit between the injector pump and the fuel tank, the improvement comprising a venting fuel valve including a valve body, mounting means for mounting said valve body on said injector pump, a fuel inlet on said valve body for receiving said fuel inlet conduit, a fuel outlet on said valve body for transmitting fuel to said injector pump, venting means in said valve body in communication with the atmosphere, valve means in said valve body movable between first and second positions, first conduit means in said fuel valve operable in said first position for effecting communication between said fuel inlet and said fuel outlet to supply fuel to said injector pump while preventing venting of said fuel outlet to the atmosphere through said venting means, second conduit means in said fuel valve operable in said second position for preventing communication between said fuel inlet and said fuel outlet and for effecting communication between said injector pump and the atmosphere through said fuel outlet and said venting means to thereby vent said injector pump and prevent flow of fuel through said fuel return conduit to said injector pump when said injector pump is caused to operate, a mounting member having a first mounting member portion for mounting on said injector pump, a second mounting member portion for mounting said valve body, means for locking said valve body on said mounting member, said mounting member comprising an elongated nipple-like member, and said first mounting member portion comprising a first threaded portion on one end of said nipple-like member, and said second mounting member portion comprising a central portion on said nipple-like member, and said means for locking said valve body on said mounting member comprising a second threaded portion at the other end of said nipple-like member, and a nut having an endless curvilinear groove mounted on said second threaded portion and received within a recess in said valve body.
