The pump has at least one pump piston, which is directly supported on the ring via the piston base thereof, or via a support element and is driven in a stroke movement upon the rotational movement of the drive shaft. The ring has an at least approximately planar contact surface in the region of the support of the piston base or of the support element, and the support surface of the piston base or of the support element on the ring is greater than the cross-sectional surface of the shaft of the pump piston. The extension of the support surface of the piston base or of the support element in the tangential direction to the rotational axis of the drive shaft is greater than the extension thereof in the direction of the rotational axis of the drive shaft.

摘要： An arrangement is proposed for forming a piezoelectric actuator, which has at least one piezoelectric element that in each case consists of a multi-layer structure of piezoelectric-layers, wherein internal electrodes arranged between the piezoelectric-layers in the direction of the build-up of the layers of the piezoelectric element, have an electrical voltage of different polarity alternately applied to them. Around the piezoelectric element, or in the case of multiple piezoelectric elements positioned in series in the activation direction, around the piezoelectric elements, and at least partially around the actuator head and the actuator foot there is arranged a covering system made from at least one layer of an insulating material. The at least one layer encloses the joints between the piezoelectric element or elements and the actuator head and the actuator foot, forming a seal.

摘要： A fuel injection device includes an injection valve connected in an injection line for the fuel and having a nozzle chamber and a control chamber that are both connected to the injection line, an on-off valve for switching back and forth between a lower injection pressure and a higher injection pressure, and a valve device for controlling the pressure prevailing in the control chamber. A shared actuator is provided for the valve device and the on-off valve, wherein the actuation distance of the shared actuator required to open the on-off valve is greater than the actuation distance required to open the valve device.
