摘要： The invention relates to a fuel injection device with a pressure intensifier (1) arranged between the pressure accumulator and a nozzle compartment. Said pressure intensifier is provided with a mobile piston unit (4) for intensifying the pressure of the fuel to be supplied to the nozzle compartment. Said piston unit (4), for controlling the pressure intensifier (1), comprises a transitional zone from a larger to a smaller piston cross-section and a differential compartment (2) defined by said transitional zone.

摘要： The invention relates to a pressure valve for installing in a feed pipe (7) between a pump working chamber (9) of a fuel-injection pump and an injection point (11) on the internal combustion engine to be supplied with fuel. The pressure valve comprises a valve body (13) with a first valve seat (17) and an axial through channel, a pressure valve closing member (19) which opens in the direction of the injection point (11), against the force of a first valve spring (23) located in said through channel (15). The pressure valve closing member (19) has a sealing surface (21) which works in conjunction with the first valve seat (17). The pressure valve also has an axial through bore (25) in the pressure valve closing member (19). This through bore (25) can be closed by a return valve (27), said return valve opening in the direction of the pump working chamber (9) and having a second valve spring (33). A fuel channel is formed between the radially exterior peripheral surfaces of each of the first and second valve springs (23, 33) and the housing walls surrounding them for the fuel to flow through without being throttled, thus ensuring an optimal unthrottled flow of fuel through the pressure valve.

摘要： Check valves (500) are incorporated into a fuel injector so as to form a controlling orifice in the system between the solenoid vales which direct fuel to the respective injection and timing chambers of the fuel injector and the chambers themselves. The precision fuel metering capability of the valve (500) is determined by an annular clearance created between the plunger (512) of the valve and the valve body (510) when the valve is in its maximum stroke. For achieving a bi-stable operation of the valve, the ratio of the plunger valve seat (510d) area to the maximum plunger valve (512b) area and the spring (514) are key parameters. The check valves (500) are formed as cartridge type check valves taht can be calibrated outside of the injector prior to the installation thereof.
摘要翻译：止回阀（500）被并入燃料喷射器中，以便在电磁阀之间的系统中形成控制孔，该燃料喷嘴将燃料引导到燃料喷射器的各个喷射和定时室以及腔室本身。当阀处于最大冲程时，阀（500）的精密燃料计量能力由在阀的柱塞（512）和阀体（510）之间产生的环形间隙确定。为了实现阀的双稳态操作，柱塞阀座（510d）面积与最大柱塞阀（512b）面积和弹簧（514）的比是关键参数。止回阀（500）形成为盒式止回阀，其在安装之前可以在注射器外部校准。

摘要： Simple requirement-dependent control of the flow of the fuel and hence the pressure in the high-pressure section are to be obtained in the high-pressure section of a (common rail) injection system, using a non-controllable high-pressure pump with check valves on the suction and delivery sides. To this end, the fuel flow is set on the low-pressure side by a controllable low-pressure pump or a downstream control valve. If the set fuel flow is lower than the maximum determined by the suction volume of the high-pressure pump, incorrect metering is prevented either by the floating piston together with a conventional check valve (17, 18) on the suction side or by a spring-loaded piston and a check valve in the form of a differential pressure valve (7, 8).

摘要： A process for manufacturing the movable element (117) of a pressure valve for fuel injection pumps by material removal. The movable element has a closing cone (123), a balance piston (128) an several fuel guiding recesses (125) extending in the axial direction of a guiding shaft (118). Several such elements (117) are simultaneously produced from a previously hardened bar, the rotation-symmetric notches (131) and openings being effected in a known manner by turning tools, whereas the recesses (125) are for example produced by rotating tools, in particular grinding tools, transversely moved with respect to the axis of the bar.
