摘要： In a fuel supply system (1), a fuel pressure regulating valve (11) disposed at a fuel outlet side of a low-pressure pump (3) in order to regulate the pressure of supply fuel from the low-pressure pump (3) to a predetermined pressure is housed inside a cylinder (31) such that a piston (32) is elastically urged by an elastic urging mechanism (33) toward a pressure receiving port (11A), the piston (32) is configured such that the pressure of the fuel at the fuel outlet side is regulated as a result of the piston opening/closing an overflow port (11B) disposed in a side wall portion of the cylinder (31) in response to the fuel pressure applied to the pressure receiving port (11A), a lubrication fuel outlet port (11C) for taking out fuel for lubrication is disposed in the side wall portion of the cylinder (31) at a position nearer to the pressure receiving port (11A) than the overflow port (11B), and lubricating-use fuel is taken out prior to the start of the pressure regulating operation.

摘要： A common-rail fuel injection system which regulates an amount of fuel delivered at every plunger(60) in a high-pressure fuel-supply pump(50), thereby enabling to control an actual common-rail pressure(Pra) restored at every fuel delivery forced by the plunger(60) so as to come in matching a desired common-rail pressure(Prt). A fundamental desired amount(Qb) of fuel delivered is found dependent on the desired common-rail pressure(Prt) derived from the engine operating conditions. A correction amount(ΔQb) of fuel delivered is calculated at every plunger(60) on the basis of a deviation (ΔPr) in the common-rail pressure(Pr), which is derived from the actual common-rail pressure(Pra) restored with the fuel delivery and sensed at every fuel delivery. Each plunger(60) delivers under pressure an ultimate amount(Qf) of fuel that is compensated with the correction amount (ΔQf) of fuel delivered, thereby making the common-rail pressure(Pr) coincide with the desired common-rail pressure(Prt).

摘要： The invention relates to a device for injecting high-pressure fuel into an internal combustion engine. An injector (25) comprises a pressure chamber (1) from which a high pressure line (3) opens into a control chamber (4) of a nozzle needle (5). The injector (25) also contains two control valves (11, 12) which are connected to low-pressure areas (9) on the discharge side. One of the control valves (11, 12) that determine the injection pressure curve (20) contains a pressure compensation system (34), enabling the injection pressure curve (20) to be varied through modification of the stroke path (23) of the nozzle needle (5).

摘要： A fuel injection pump for supplying fuel to an internal combustion engine includes a bore (13) containing a cam actuated pumping plunger (9). The bore is connected to an outlet (16) during inward movement of the plunger and a spill valve including a spill valve member (19, 19A), is operable to spill fuel from the bore to prevent delivery of fuel to the associated engine. The spill valve member includes a piston portion (22) slidable in a cylinder (17, 17A) to which fuel under pressure from the bore can be admitted to move the spill valve member to the open position against the action of a spring (21, 21A). The admission of fuel under pressure to the cylinder can be effected by an electromagnetically operable valve (22A), or by the use of a control sleeve (30), recesses on the internal surface of which in conjunction with porting in a rotary part of the pump, form a control valve.

摘要： A rotary distributor fuel pumping apparatus has a spill valve (25) which is operable to terminate delivery of fuel by a cam actuated pumping plunger (15). The spill valve is operable by a first piston (44) and a further piston 46 is provided the extent of movement of which is limited by an adjustable stop (54). A further plunger (51) is actuated in synchronism with the pumping plunger (15) and supplies liquid to the cylinders containing the pistons. When during the inward movement of the plungers, the movement of the further piston is halted the first piston will move to open the spill valve to terminate delivery of fuel.
