摘要： A dual-tube shock absorber having a damping piston, which is joined to a vehicle body via a piston rod; an inner cylinder, guiding the damping piston, that is disposed in an outer cylinder which is connected to the vehicle axle and that together with the damping piston encloses an upper and a lower liquid-filled pressure chamber; a check valve which enables a liquid flow from an compensation chamber enclosed by the outer and inner cylinders to the lower pressure chamber; and a line, joining the upper pressure chamber to the compensation chamber, in which line a device is disposed that effects the damping of the shock absorber and is preferably electrically adjustable. To assure a long service life of the device, which is preferably embodied as a throttle valve, and to facilitate the laying of control cables, the line is extended through the damping piston, and the device is integrated with the damping piston.

摘要： A hydraulic shock absorber with automatically adjustable damper force which actuates an electromagnetic rotary adjuster for a control slide that monitors a sole flow cross section. The rotary adjuster is embodied as a permanently excited single-winding rotary adjuster, and because of its permanent magnetic poles in the rotor, even when it is currentless it furnishes a torque that assures safety resetting of the rotary adjuster if the current fails. The hydraulic shock absorber is intended for controlling the undercarriage of a motor vehicle.

摘要： A known shock absorber including a throttle cross section of a throttle passage which is electrically variable via a magnet, to adjust damping of fluid between separate work chambers. If the magnet has no current in the event of an electrical defect, then the throttle cross section of the throttle passage attains its minimum opening, and maximum damping is attained the shock absorber includes a different further throttle passage which is uncovered in the event of an electrical defect. As a result, in the event of an electrical defect an arbitrarily preselectable, preferably approximately average damping is brought about by the further throttle passage.

摘要： A shock absorber for use in motor vehicles which includes a piston within a packet, inside the piston the entire quantity of the damping fluid exchanged between two work chambers flows via a throttle cross section the size of which is defined by an electromagnetic adjusting device comprising primarily a magnet coil and an armature. The armature is annular and merges with an annular control slide provided with a slide control edge, which slide, in cooperation with a piston control edge on the piston determines the size of the throttle cross section. The control slide and armature are statically in pressure equilibrium, and because of their annular embodiment they have only a slight weight, so that the shock absorber operates with short adjusting times. By a defined profile of the slide control edge or piston control edge, certain damping characteristics are attainable.

摘要： In previously known shock absorbers, a throttle cross section can be controlled with the aid of a control slide. Because flow forces can never be avoided entirely, the magnetic force must be controlled as a function of the flowing pressure fluid flow. In the cylinder proposed here, having a control slide, an additional force acting upon the control slide results, which is directed counter to these flow forces and can at least partially compensate for them. The proposed cylinder is intended in particular for use as a shock absorber for vehicles.

摘要： A device for actuating a butterfly throttle valve of an internal combustion engine includes a hydraulic setting member for rotating a shaft of the throttle valve. The hydraulic setting member is driven by a branch flow of fuel delivered by a fuel pump and acting as pressure medium. The branch flow passes through a series of connection of adjustable throttles connected in a hydraulic bridge circuit. The throttles are adjusted by a regulating signal corresponding to the difference between an actual position signal delivered by a position sensor coupled to the throttle valve, and a desired position sensor coupled for example to a gas pedal of the motor vehicle.

摘要： A microvalve has at least two pressurized-medium connections means forming a valve seat between the connections, a closure member cooperating with the valve seat, an electrical actuating unit deflecting the closure member, and a membrane which moves the closure member in opposition to he electrical actuating unit and adjoins a space which can be loaded with pressurized medium. The membrane has an area which is substantially reduced relative to the valve seat and is firmly joined to the membrane and also has a pressure-loaded area. The closure member has a ring-shaped pressure-compensation area which is opposite to the membrane and extends radially outwardly of the reduced surface of the membrane and counteracts the pressure loaded area of the membrane, the pressure-loaded area of the membrane and the pressure-compensation area of the closure member are essentially equally large.
