摘要： The invention relates to a fuel injection valve for internal combustion engines comprising a hollow needle (7) for opening and closing at least one external injection opening (8) which interacts with a valve seat (4). An internal needle (5) which interacts with the valve seat (4) for opening and closing at least one internal injection opening (6) which is arranged in the hollow needle (7), and an intermediate chamber (15) which is embodied between the hollow needle (7) and the inner needle (5), said hollow needle being connected to a pressure chamber (11) which surrounds the hollow needle (7) via an opening (24) in the hollow needle (7). The inner needle (5) is guided to a guiding section (14), which is close to the valve seat, in the hollow needle (7). At least one passage (30, 32) is formed on the guiding section (14) through which the fuel can flow from the intermediate chamber (15) to the inner injection opening (6, 8). At least one passage (30, 32) is formed such that a tangential force is exerted upon the inner needle (5) when the fuel is cross-flown.

摘要： PROBLEM TO BE SOLVED: To eliminate a change of adjusted preload and prolong the service life of a pressure sensor, by improving the conventional type provided with a casing arranged in the through hole of central closing screw in a fuel jetting pump, in a pressure sensor for detecting a pressure in the pump working chamber of the fuel jetting pump. SOLUTION: A casing is provided with a casing front part 8, and the casing front part 8 is welded to a holding part 16 for measuring member and is bound with the holding body 16 for measuring member, a measuring member 14, a pressure transmitting member 12, and a diaphragm 10 forming the bottom of the casing front part 8 by applied preload regulated in the pressure transmitting direction, forming an unremovable measuring head 6. The measuring head 6 is brought into contact with other constituent parts of the pressure sensor 1 and a through hole 20 by means of only an outer flange 20 arranged around the outer circumference of the measuring head 6.

摘要： The invention relates to a distributor injection pump comprising a housing (10) and a roller ring (12) which is positioned in said housing in an adjustable manner and is provided with at least one roller (20). A cam plate (28) for actuating a pump piston can be supported on said roller. The roller is mounted in the roller ring using a bolt (24) which extends in a radial direction in relation to the central axis of the roller ring. The aim of the invention is to prevent damage to the housing caused by the radial force exerted outwards on the bolt that occurs when the roller is under stress. To achieve this, a support element (40) is provided on the radial end of the bolt (24).

摘要： A fuel injection valve, having an outer valve needle cooperating with a valve seat for opening and closing at least one outer injection opening, an inner valve needle disposed in the outer valve needle and cooperating with the valve seat for opening and closing at least one inner injection opening. The fuel pressure in a control chamber that can be filled with fuel under pressure acts on the outer valve needle and the inner valve needle in such a way that a closing force in the direction of the valve seat is exerted on the inner valve needle and the outer valve needle. An inner pressure face disposed on the inner valve needle and a shoulder is disposed on the outer valve needle, which each, on being subjected to pressure, exert a hydraulic opening force, oriented counter to the closing force, on the inner valve needle and the outer valve needle. The outer valve needle is at least partly surrounded by an inflow chamber, in which fuel under pressure is always present, and the inner pressure face and the outer pressure face are always subjected to the fuel of the inflow chamber.

摘要： An injector for high-pressure injection of fuel in self-igniting internal combustion engines includes an actuator valve for opening and closing the injector; a nozzle needle, which in the closed state of the injector closes at least one injection opening; a metering valve, which establishes a hydraulic communication between the actuator valve and the relief chamber of the injector; a pressure holding device, which serves to maintain a static pressure required for the metering valve; and a first control quantity line for control quantities that flow via the actuator valve, and a second control quantity line for control quantities that flow via the metering valve. The pressure holding device dynamically separates the control quantities of the metering valve from the control quantities of the actuator valve by means of a hydraulic fluctuation damper.

摘要： Pressure sensor with a measurement head which is joined to its housing by a weld. The pressure sensor (1) has a housing with a separate forward part (8), which is joined to a measurement element support (16) by a welded joint (18). The measurement element (14), the pressure transfer element (12) and the membrane (10), which forms the bottom of the forward housing (8), are pre-pressurised and form a nondetachable measurement head (6), which is only in contact with the rest of the measurement head via the outer circumference of head's outer flange (20).
