A pumping system includes s pump, a mechanical coupling device, and a cam shaft. The pump is effective to transfer fuel into an engine. The mechanical coupling device is coupled to the pump. The cam shaft couples to the mechanical coupling device. The cam shaft has an axis extending there through and rotates about the axis. The rotating of the cam shaft is effective to engage the mechanical coupling device and transfer a mechanical force created by the rotating to the mechanical coupling device. The mechanical coupling device is engaged to allow the mechanical force to be transferred to the fuel pump and activate the fuel pump when fuel is to be moved by the pump. The mechanical coupling device is disengaged to disallow the mechanical force from being transferred to the fuel pump and prevent the operation of the fuel pump.

Pump control apparatus and method

A flow control valve () for a direct injection pump () has an inlet end (), an inlet valve (), a compression chamber (), a pump piston (), and an outlet (). The valve () has a housing () and a non-electrically operated control plunger () movable within the housing. The control plunger engages with and disengages from the inlet valve to control opening and closing of the inlet valve. A spring () biases the control plunger away from the inlet valve. The pump and housing define port structure () fluidly connecting the outlet with a volume () that communicates with the control plunger such that when fluid pressure at the outlet is greater than a certain value, the fluid pressure in the volume alone causes the control plunger to move against the spring and engage the inlet valve to hold the inlet valve in an open position.

Pressure operated mechanical flow control valve for gasoline direct injection pump

A fuel pressure damper (') includes a housing () defining an inlet () constructed and arranged to receive fuel. An orifice disc () is provided at the inlet and includes at least one orifice (). A cover () is coupled to the housing. A flexible diaphragm () has a periphery fixedly secured to at least the housing or the cover and has a freely movable central portion (). A compression spring () biases the diaphragm to a normal position. In an operating position, the central portion of the diaphragm alone, or in combination with the spring, is constructed and arranged to dampen fuel pressure pulsations at the inlet. The orifice is constructed and arranged to ensure that pressure pulsations of a certain magnitude are prevented from entering the damper and damaging the diaphragm.
