摘要： A magnetic linear drive includes an elongated cylindrical armature which is supported for axial displacement in a guiding pipe made of a pressure-resistant material. Two axially spaced solenoid windings are mounted on the guiding pipe and are interconnected by a permanent magnet. The solenoid windings are provided with lateral magnetically conducting cores the ends of which communicate with annular grooves formed in the guiding tube. The grooves are filled with a magnetically conductive material forming the poles of the electromagnet. In the region of the poles, the armature is formed with control flanges of different depths which are acted upon by the magnetic flux to impart the axial movement to the armature. One end of the armature is formed with a measuring flange which cooperates with measuring coils mounted on the guiding pipe.

摘要： The hydraulic setting device has a differential cylinder (11) whose annular space (14) is continually subjected to pressure by a pump (16). The pressure space (18) at the large piston surface is connected to the pump via a connection conduit (41). A conduit branch, which leads to a control valve (21), emerges from this connection conduit (41). At the other end, this control valve is in connection with a return conduit (26). The pressure in the conduit branch (19), and therefore in the pressure spaces (14, 18) of the differential cylinder, can be varied by appropriate activation of the control valve.

摘要： A hydraulic control circuit for a cylinder-and-piston unit includes a relatively small electrohydraulically operated servo-control valve, a main pressure conduit including a measuring throttle, an auxiliary control valve cooperating with an additional pressure conduit connected parallel to the main pressure conduit to branch the pressure fluid in response to a predetermined level of pressure difference occurring across the measuring throttle. In this manner the servo-control valve can control a system of pressure fluid which is substantially larger than the nominal flow rate of the servo-control valve.

摘要： A high pressure fuel pump encompasses at least one delivery chamber and one high pressure outlet. In addition, a pressure limiting valve with a valve that is actuated by a pressure differential is provided that can open from the high pressure outlet to the delivery chamber. On a high pressure side of a valve seat of the pressure limiting valve, it is advantageous that a throttle device is provided, whose free cross section is at most approximately equal to a desired maximum opening cross section of the pressure limiting valve.

摘要： A pressure and delivery regulating device for an adjustable pump includes a directional control valve connected in a discharge conduit and to a control conduit branching from the discharge conduit between the pump and the directional control valve. The control conduit leads to a setting piston for the adjustment of the pump. The directional control valve is controlled by a solenoid which in turn is controlled by a control system consisting of a regulating circuit, a delivery limiting circuit and a control circuit for the solenoid. The output signal from the regulating circuit controls a desired delivery value signal supplied to the delivery limiting circuit. A follow-up circuit connected between the regulating circuit and the delivery limiting circuit corrects the regulating signal and a circuit for producing a direction dependent signal from the actual pressure provides a damping of the regulating circuit.
