    摘要: A pressure regulator can be used particularly in a CNG-operated motor vehicle as an electronically controlled pressure reducer for maintaining the gas pressure constant on the injection valve used for filling the respective cylinder. The pressure regulator is composed of a control unit (1), a pressure reducer (3) that is controlled by the control unit (1), and a throttle (2) which connects the gas outlets (20, 40) of the working chamber (17) of the control unit (1) and the pressure reducer (3). A piezoelectric actuator (11) which affects the valve (21, 22) of an overflow device (14) makes it possible to specifically modify the gas pressure (P2) in the working chamber (17) of the control unit (1) and simultaneously influence the position of the valve (38, 39) of the overflow device (33) of the pressure reducer (3), thus allowing the output pressure (Pout) of the pressure reducer (3) to be adjusted to a predefined desired value.

    摘要: An injection valve for injecting fuel comprises a valve housing (1) inside of which a drive unit (15) controls the movement of a valve needle (5) that is pretensioned by a spring (11). The injection valve also comprises a main chamber (27), which is provided inside the valve housing, is filled with fuel and accommodates the valve needle (5), and comprises a hydraulic bearing for the drive unit (15). The hydraulic bearing has a hydraulic chamber (29) that is connected to the main chamber (27), whereby fuel serves as the operating substance of the hydraulic bearing.

    摘要: A device for controlling a capacitive charge, in particular a piezoelectric actuator (2) has a signal generator (6) which is used to control a first end step (1) which is used to produce a discrete signal on the capacitive charge. Device has a second end step (3, 4) which is used to generate a continuous signal on the capacitive charge. A counter-coupling of a deviation of an actual discrete signal is produced by a continuous signal required on the capacitive charge.
