  • Patent number: 8596609
    Abstract: The invention relates to a solenoid valve with a magnet assembly and a valve cartridge having a pole core, a valve insert connected to the pole core, an armature which is guided within the valve insert in an axially movable manner between a closed position and an open position and is coupled to a closing element, and a valve body which is connected to the valve insert and has a main valve seat which is arranged between at least one first flow opening and a second flow opening. The axially movable armature, when the magnet assembly is energized, is moved by a generated magnetic force within the valve insert in the direction of the pole core counter to a spring force of a resetting spring and counter to a fluid force in order to lift the closing element out of the main valve seat; and to permit a flow of fluid between the at least one first flow opening and the second flow opening.

  • Patent number: 6121702
    Abstract: The invention relates to an electric motor having a preferably cup-shaped motor housing and a contacting device for supplying electrical energy from outside to corresponding motor parts. The contacting device includes a busbar, which is disposed in the interior of the housing and can be shifted at least partially through an opening in a housing wall, and the outer end of the busbar is electrically connectable to a connection line and the inner end of the busbar is electrically connectable to corresponding motor parts.

  • Patent number: 5988774
    Abstract: A hydraulic brake system for a vehicle with an anti-lock arrangement operable by wheel brake pressures are individually variable in front wheel brakes and rear wheel brakes, connected to diagonal brake circuits, of a four-wheeled vehicle, in order to reduce or eliminate a threat of wheel locking. The anti-lock arrangement has at least one return pump per brake circuit. The anti-lock arrangement is equipped with a total of four electrically controllable valves. In each of the brake circuits I, II there is one first valve between the master cylinder and a front wheel brake and one second valve between the master cylinder and the rear wheel brake. All the valves are embodied as normally open valves and are electrically closable. Inlets of each of the return pumps communicate directly with the respective front wheel brakes and indirectly with the rear wheel brakes through throttles. Check valves that open toward the inlets of the return pumps are provided in series with the throttles.

  • Patent number: 5260651
    Abstract: The travel measuring system serves to detect a control position of one body relative to another body. Disposed on one of the bodies is a coil and a structured material that influences the inductance of the coil is disposed on the other body. The influence of the material varies along a travel distance to be measured. This serves to ascertain the control position. The travel measuring system according to the invention may be used in a shock absorber to ascertain a stroke.

  • Patent number: 5205581
    Abstract: In a system for controlling a chassis, in particular for controlling spring cylinders that can simultaneously perform the function of a semiactive shock absorber and are disposed between wheel suspensions and the vehicle body, at least one chamber of the spring cylinder is intended to communicate via a line or branch line with a pumping device, reservoir or the like for a pressure fluid, and at least one control member is connected between the pump device, reservoir or the like and the chamber. A control valve, which responds to a change in pressure in a shunt between the control valve and a line, is disposed in the control member.

  • Patent number: 5085299
    Abstract: A shock absorber which in an event of an electrical defect provides a predetermined throttle cross section which provides a pressure drop in the throttle cross section that determines damping of fluid flow from one work chamber to another work chamber. Thus, in an event of a defect in a control system, an arbitrarily selectable and preferably approximately average damping is produced.

  • Patent number: 4904026
    Abstract: A brake system having a master brake cylinder with at least one piston in a stepped bore in which the piston is acted upon at one end by a piston rod and on the other end defines a pressure chamber, from which an outlet or a brake line leads to wheel brake cylinders of at least one brake circuit. The pressure chamber, or the brake line discharging from this pressure chamber communicates on the one hand with a compensation chamber and on the other with an annular chamber, the volumes of both these chambers being variable contrarily by movement of the piston. The connection between the pressure chamber and the compensation chamber is interrupted by a valve, and a connection is then established with a fluid reservoir. A suitable amount of fluid can then be transported from this fluid reservoir into the compensation chamber by means of a return pump.

  • Patent number: 4798421
    Abstract: A plunger system in a brake line between a master brake cylinder and a wheel brake cylinder of a vehicle, for modulating a brake pressure in the event of a sensor-detected danger of wheel locking or wheel spinning. The plunger system has a plunger that is axially displaceable in a housing. At one end, the plunger engages a variable pressure chamber toward the master brake cylinder and at the other it engages a variable pressure chamber toward the wheel brake cylinder. It has an axial bore, through which a rod passes, between the two pressure chambers, and this bore can be closed on opposite ends if there is a danger of wheel locking or if wheel spinning occurs. The closure of the axial bore is effected by an axial motion of the plunger, which takes place if the wheels lock, on the one hand, and if they spin, on the other.
