摘要： A control valve arrangement for use in controlling fuel pressure within a control chamber (30) includes a control valve member (32) which is movable between a first position in which the control chamber (30) communicates with a source of high pressure fuel, and a second position in which the control chamber (30) communicates with a low pressure fuel drain and communication between the control chamber (30) and the source of high pressure fuel is broken. The control valve arrangement also includes restricted flow means (55, 70, 86) for restricting the rate of flow of fuel from the control chamber (30) to the low pressure fuel drain when the control valve member (32) is moved from the first position to the second position. It is desirable for the restricted flow means to be configured and arranged such the rate of flow of fuel from the source of high pressure fuel to the low pressure drain for the period of time for which the control valve member (32) is moving between the second position and the first position is also restricted.

摘要： A cam arrangement for use with a high pressure fuel pump arrangement for delivering fuel to an associated engine, the cam arrangement including at least two cams (28) that are mounted, in use, upon an engine camshaft and each of which is arranged to drive a respective pumping plunger (16) of the fuel pump arrangement, wherein each plunger is driven to perform a pumping stroke, against return biasing means (32), during which fuel within a pump chamber (22) associated with each plunger is pressurised, and whereby said return biasing means (32) effects a plunger return stroke, and wherein each cam (28) is oriented relative to the or each other cam and has a surface (50) shaped such that the associated plunger return stroke is interrupted to define at least one step of plunger movement that is substantially synchronous with the pumping stroke of another of the plungers (16) of the pump, thereby to reduce negative torque loading of the camshaft

The control valve arrangement includes a restricted flow path for restricting the rate of flow of fuel from the source of high pressure fuel to the control chamber when the control valve member is moved towards its first position. The provision of the restricted flow path prevents unbalanced hydraulic forces acting on the control valve member when the control valve member is moved towards its first position, which can otherwise lead to valve needle dither between injecting and non-injecting states.

摘要： A shut off valve arrangement for use in a fuel injection system includes a shut off valve member operable between a closed position in which the shut off valve member is engaged with a shut off valve seating and an open position in which the shut off valve member is disengaged from the shut off valve seating to control the supply of fuel to the injector through a fuel supply passage. The shut off valve member includes a first surface that is exposed to fuel pressure within a shut off valve control chamber, a second surface exposed to fuel within the fuel supply passage and a third surface exposed to fuel pressure in a balance chamber, wherein the shut off valve arrangement is provided with a control valve for controlling the pressure of fuel within the shut off control chamber, thereby to control movement of the shut off valve member between the open and closed positions. The shut off valve arrangement is further provided with communication means between the fuel supply passage and the balance chamber so that a balancing force acting on the third surface due to fuel pressure in the balance chamber opposes an opening force acting on the second surface.
