Abstract:
An improved fuel injection pump is provided for an internal combustion engine (e.g., diesel engine), and is configured such that the secondary hand pump of the prior art can be eliminated. To achieve this result, the injection pump employs a one-way bearing or clutch on the input side of the drive shaft of the injection pump. By employing a one-way bearing or clutch, such as of the concentric roller type, or other suitable clutch, the fuel injection pump can be operated by direct coupling of the engine and the drive shaft of the fuel injection pump. Also with this configuration, once the engine is stopped, the drive shaft of the fuel injection pump can be manually driven in order to prime the system. Accordingly, by locating a one-way bearing or similar clutch device along the driveline of the fuel injection pump, the fuel injection pump can be both manually operated when the engine is shut off and automatically driven when the engine is running.

Claim (Index 5):
An injection pump of a fuel delivery system, the injection pump comprising:\n an injection pump housing; a pump mechanism disposed within the housing; a fuel input port configured to be connectable to a source of fuel at a first pressure; a fuel output port configured to be connectable to at least one fuel injector; a transmission interface configured to be coupled in driving relationship with an internal combustion engine; a pump drive shaft rotatable supported by the injection pump housing and operatively coupled to the pump mechanism, wherein rotation of the pump drive shaft transmits fuel supplied to the input port at a first pressure to the fuel output port at a second, higher pressure; and a one-way clutch arrangement coupled between the transmission interface and the pump drive shaft, wherein the one-way clutch arrangement is configured such that: (1) torque transmitted to the transmission interface by the internal combustion engine in a first rotational direction is transferred to the pump drive shaft; and (2) torque transmitted to the drive shaft in the first direction via operator input is not transferred to the transmission interface.
