摘要： The invention related to a method for low loss periodic control of a capacitive load (CP), in particular of a piezoelectric actuator. In this method, before load control begins, a capacitor bank (C1) is charged via a voltage source (UB) until the oprating voltage of load (CP) is attained; then the load (CP) is charged from the capacitor bank (C1) via a series resonant circuit formed by a reactance coil (L1), a freewheeling diode (DE), and by the load (CP). In this method, when a load is required, the load (CP) is linked via discharge switch (SE) to the reactance soil (L1) which is itself connected via a freewheeling freewheeling diode (DL) to the capacitor bank (C1) in such a way that the load (CP) is discharged until a residual voltage (UR).

摘要： A fuel injection valve for an internal combustion engine includes a valve block; an injection nozzle carried by the valve block and having a nozzle opening; a valve needle slidable in the injection nozzle for assuming closed and open positions to block and, respectively, to unblock the nozzle opening; a closing spring urging the valve needle into the closed position; and a pressurized fluid port in the valve block. The nozzle opening is in communication with the pressurized fluid port in the open position of the valve needle. A discharge port is defined in the valve block for carrying fluid away therefrom. An equalizing piston, which is slidably disposed in a work chamber in the valve block, is connected with the valve needle. A control plunger is movable in the valve block and has a first position and a second position. In the first position the control plunger prevents communication between the discharge port and the work chamber and maintains communication between the pressurized fluid port and the work chamber for maintaining the equalizing piston and the valve needle in the closed position. In the second position the control plunger prevents communication between the pressurized fluid port and the work chamber and maintains communication between the discharge port and the work chamber for moving the equalizing piston and the valve needle into the open position. A throttle is disposed in the discharge port for braking fluid flow from the work chamber through the discharge port.

摘要： A sensor for detecting movement of a control element moved by an electromagnetic actuator comprises a fixed coil arrangement having at least one coil connected to a current supply and to a signal detection device. A housing circumferentially encloses the fixed coil arrangement. The housing comprises a magnetically conductive material with poor electrical conductivity. An axially movable rod-shaped sensor part of a magnetizable material is connected to the control element. A short circuit element comprised of an electrically conductive material with low ohmic resistance is disposed on the rod-shaped element and is delimited in a longitudinal direction of the rod-shaped element by two outer edge regions. The short circuit element is dimensioned in the movement direction of the rod-shaped element so that only one of the outer edge regions of the short circuit element is always positioned inside the fixed coil arrangement during the back and forth movement in a stroke region of the fixed coil arrangement.

摘要： An actuator assembly for operating a setting member includes an actuator body undergoing a dimensional change upon applying electrical energy thereto; a preliminary pressure chamber for accommodating liquid; a diaphragm sealing the preliminary pressure chamber and being displaceable by the actuator body; a valve member carried by the diaphragm; a transfer chamber for accommodating liquid; and a displaceable plate body disposed in the preliminary pressure chamber and sealingly bounding the transfer chamber. The diaphragm, as it is moved by the actuator body, displaces the plate body. A displaceable piston body sealingly bounds the transfer chamber and has a surface which is smaller than the surface of the plate body, whereby the plate body--with the intermediary of the liquid--displaces the piston body to a greater extent than the displacement of the plate body. The piston body, as it moves, displaces the setting member. A valve opening provided in the plate body is closed or opened by the valve member carried by the diaphragm. In the open position of the valve member, the valve opening establishes a hydraulic communication between the preliminary pressure chamber and the transfer chamber.

摘要： A process and a device to measure the compression volume in a cylinder of an internal combustion engine in which process an overpressure in the combustion chamber is produced by introducing a controlled gas flow through existing spark plug or injection nozzle bores. A pressure expansion in the combustion chamber, caused by leakage of the piston rings, is analyzed. The size of leakage is determined by measuring step-by-step varied gas flows, introduced into the chamber and flowing out of the chamber through leakage, and measuring the resulting pressures built up in the chamber at a stationary state of flow and pressure. By combining the leakage characteristic and the pressure expansion characteristic the leaking volume having flowed out of the chamber during the expansion can be determined. With the knowledge of the leaking volume and the pressures and temperatures at the beginning and at the end of the expansion, the compression volume can be calculated with the aid of the general gas equation. In contrast to other known methods, the process makes it possible to determine the compression volume reliably without the need of dismounting the engine or sealing the combustion chamber.
