Abstract: A fuel injector includes an auxiliary valve member that can assist in raising a mean injection pressure, increase a nozzle valve opening pressure, and hasten the closure rate of a nozzle valve member over an equivalent fuel injector without the auxiliary valve. The auxiliary valve member is fluidly positioned between a needle control chamber and a high pressure space, which includes a fuel pressurization chamber within the fuel injector. The auxiliary valve member includes a closing hydraulic surface exposed to fluid pressure in the high pressure space. The plumbing and the auxiliary valve member allow high pressure fuel to act upon a closing hydraulic surface of the nozzle valve member to increase valve opening pressure and mean injection pressure. The needle control chamber may be vented or may be a closed volume when the auxiliary valve member is in its closed position. The invention is potentially applicable to any fuel injector, but finds the preferred application in cam actuated fuel injectors that include an electronically controlled spill valve.

Abstract: The invention relates to an injection device, in particular for injecting fluid into an exhaust tract of an internal combustion engine, having a valve unit which comprises a valve needle, an injection chamber having at least one injection opening, and a control chamber, wherein the injection device is designed so that a pressure differential between the injection chamber and the control chamber brings about a displacement of the valve needle between an open position in which the valve needle releases a fluid flow through the injection opening, and a closed position in which the valve needle closes off the injection opening. The injection device also has a pump unit integrated in the injection device. The pump unit is designed so as to draw in fluid from the fluid inlet during operation and to provide said fluid to the valve unit under increased pressure.

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: The inventive discharge rate and pressure control solenoid valve (1) is used for a circuit consisting of a low pressure part and a high-pressure part and controls the discharge rate of a low-pressure fluid with the aid of a sliding spool (18) in a liner (22) provided with at least one fluid feeding orifice (20) and one fluid exhausting orifice (21) respectively. Said spool (18) is electrically actuated by means of an electromagnet acting in an opposite direction to recoil means (26) for closing the passage between the feeding (20) and exhausting (21) orifices when a control current for the electromagnet is equal to zero and for gradually opening said passage according to a threshold value of the flow, the pressure control being applicable to a high-pressure fluid. The recoil means (26) are inserted between the spool (18) and a flap device which closes an inlet orifice in the liner (22) of a high pressure fluid and is connected to the low-pressure fluid feeding orifice at least at a slide position corresponding to the control current when it is less than said threshold value. The recoil means (26) are positioned and dimensioned in such a way that the flap is openable when the current is equal to or near zero in order to drop the pressure in the high pressure circuit.

Abstract: An arrangement in a fuel injection system for controlling the fuel injection includes a body part having a space, through which the fuel to be injected during operation flows, and a fuel inlet opening and an outlet opening opening into the space. A piston is arranged movably inside the space, the piston having a channel arranged therein for creating a flow connection between the fuel inlet opening and the outlet opening, whereby the piston divides the space into a first part connected with the inlet opening and a second part connected with the outlet opening. A spring creates a force acting on the piston in a direction opposite to that of the main fuel flow. The piston and the body part are formed so that when the piston is in the end adjacent the fuel inlet opening it delimits a third space, the volume of which depends on the mutual positions of the piston and the body part.
