Abstract: The invention relates to a system for injecting fuel into a combustion chamber of an internal combustion engine, having a fuel injector, which can be subjected to fuel at high pressure and which is actuatable via a metering valve, by which the pressure in an injection valve member control chamber or in a control line is controllable such that an injection valve member opens and closes for injecting fuel. The injection valve member control chamber can be evacuated via an outlet throttle device into a control line which has a smaller throttle cross section than an inlet throttle device, by way of which the injection valve member control chamber can be filled.

Abstract: A fuel system shut-off valve includes a valve body bounding a fuel space, the valve body having an inlet opening and an outlet opening communicating with the fuel space. A piston assembly in the fuel space includes a main piston member that is movable relative to the valve body and an auxiliary piston member that is movable relative to the main piston member. The piston assembly either allows or prevents fuel flow through the valve from the inlet opening towards the outlet opening depending on the position of the auxiliary piston member. A force member urges the piston assembly towards the inlet opening.

Abstract: A high-pressure-side valve portion makes contact with and moves from a high-pressure seat surface formed in a body to control communication between a control chamber communication passage and a high-pressure passage. A low-pressure-side valve portion makes contact with and moves from a low-pressure seat surface formed in the body to control communication between an exhaust passage and a second intermediate chamber. A releasing portion in the high-pressure-side valve portion communicates with the control chamber communication passage when the high-pressure seat surface is in contact with the high-pressure-side valve portion to block the control chamber communication passage from the high-pressure passage. A valve element internal passage is formed in the valve element to communicate the releasing portion with the second intermediate chamber.

Abstract: A flow control valve (15) for a direct injection pump (10) has an inlet end (12), an inlet valve (26), a compression chamber (48), a pump piston (14), and an outlet (13). The valve (15) has a housing (16) and a non-electrically operated control plunger (22) 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 (28) biases the control plunger away from the inlet valve. The pump and housing define port structure (38, 44) fluidly connecting the outlet with a volume (42) 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.

Abstract: A passive hydraulically actuated non-electric shutdown pressure relief valve relieves pressure in the high pressure volume of a low static leak common rail fuel system after shutdown. When the common rail fuel system is in operation, a transfer pump provides medium pressure to hold the shutdown pressure relief valve closed. At shutdown, the residual medium pressure downstream from the transfer pump decays back to tank, and the residual high pressure trapped in the common rail and fuel injectors pushes open the shutdown pressure relief valve to release the high pressure after back to tank.

Abstract: Method and apparatus for controlling needle seat load in very high pressure diesel injectors. In accordance with the method, a needle control piston responsive to hydraulic forces for controllably forcing the injector needle against the needle seat is provided, as is a stop for the needle control piston to limit the needle control piston movement toward the needle seat. This provides a stop for the needle control piston, so that the compressive deflection between the needle control piston and the needle seat limits the force of the injector needle on the needle seat against increasing hydraulic forces on the needle control piston once the needle control piston reaches the needle control piston seat.
