    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: Methods and arrangements for determining the fineness of a ground material in a mill are provided, wherein the acoustic spectrum of the mill during the grinding process is used for concluding the fineness. The mill comprises a drum in which the ground material is present during the grinding process, said drum being driven by a magnetic drive having at least one magnetic segment during the grinding process, so that a rotating magnetic field generated with the aid of the magnetic drive causes the drum to rotate. In order to determine the acoustic spectrum, a voltage induced in a coil of the magnetic segment is determined at least intermittently. On the basis of a model, using the detected time-dependent induced voltage, conclusions can be drawn about the acoustic spectrum and therefrom about the fineness.

    摘要: The compensation element is compensating for temperature-conditioned length changes of an object. An injection valve that is fully functional in the entire range of the operating temperatures of a motor requires a device that compensates thermally conditioned length changes of the mechanical components (piezo-electric actuator, valve lifter, housing, etc.). This device should be capable of absorbing great forces and allow a stiff bearing of the actuator. The compensation element (3) has an oil-filled chamber (21) is composed of an actuator-side upper part (18), of a lower part (19) supported on a stiff bearing (valve housing 17), and of a structure (annular seal element 20) sealing the chamber (21) and yielding in an axial direction. Since the compensation element (3) is fitted into an annular holder (4) with little lateral play, every temperature-conditioned change of the oil or, respectively, chamber volume results in a displacement of the upper housing part (18) in an axial direction that is proportional to the volume change. As a result of a corresponding dimensioning of the chamber height, temperature-conditioned length changes of the valve housing (4) and of the piezo-electric actuator (2) can be compensated using the extremely compactly constructed and comparatively rigid compensation element (3).

    摘要: Drive elements whose physical volume is considerably smaller than piezoelectric actuators for comparable mechanical characteristics and actuation travels can be developed on the basis of the magnetostrictive material Tb.sub.x Dy.sub.1-x Fe.sub.2 (Terfenol). Despite these characteristics, magnetostrictive actuators have until now been used only where no rapid switching processes or actuation movements are required. An actuator of compact construction responds to an electrical drive signal very quickly and can produce large actuation forces. The actuator typically contains N.apprxeq.100 drive elements (1, 1') which are arranged one above the other in the form of a stack, are each of layered construction, and are provided with electrical connections. The drive elements (1, 1') each have a small metal plate (4, 4'), which is arranged between two insulators (2, 2', 3, 3'), and an actuator element (5, 5') which is manufactured from Terfenol. When current flows through it, the small metal plate (4, 4'), which is slotted in a U-shape, acts as a planar annular coil whose magnetic field passes through the actuator element (5, 5') and causes magnetostriction there.
