摘要:
The positioning of the actuating drive in a fuel injector with a piezoactor (2) that is screwed into the housing (1) of the fuel injector is performed by applying a voltage (U) to the piezoactor (2) that corresponds to a given idle stroke (h), and the surface grinding of the housing (3) and base plate (4) of the piezoactor (2) when voltage is applied. Between the housing (1) of the fuel injector and the housing (3) of the piezoactor (2), there is also provided a compensation collar (9) of a suitable thickness.

摘要:
An electrohydraulically actuatable injection valve includes a control piston which divides an annular conduit from a control chamber disposed between the control piston and an actuator rod. A spring is disposed between the control piston and the actuator rod. The annular conduit also communicates through a control valve with a drain. If the control valve is closed with the injection valve open, the control piston opens a communication between the annular conduit and the control chamber, so that a nozzle needle is pressed onto an associated valve seat and abruptly stops the injection.

摘要:
An injector for an injection system of an internal combustion engine, with an injector head (1), a nozzle (13) for injecting fuel, a control unit (12) for controlling the transfer of fuel from the injector head (1) to the nozzle (13) and an actuator (6) for the mechanical activation of the control unit (12) in order to control fuel injection, an injector housing (2), which receives at least the control unit (12), being integrally formed on the injector head (1) at the bottom.
摘要:
A speed governor for injection pumps in internal combustion engines with a regulating sleeve which at maximum rotational speed of the internal combustion engine is displaced as a function of speed within the regulating sleeve travel against the force of the main regulating spring that acts on a force transmitting lever. The regulating movements of the force-transmitting lever are transmitted onto the fuel delivery adjusting member of the injection pump by means of at least one intermediate lever. The internal combustion engine rotational speed can be influenced by means of an operating element adapted to be controlled. In case of a needed change of the beginning of the full-load speed regulation of the internal combustion engine, the spring travel of the main regulating spring is influenced by means of a force-transmitting element.
