Abstract: A valve for controlling liquids for its actuation is provided with a liquid-filled coupling chamber, which is disposed between a step-up piston, actuatable by a piezoelectric actuator, and a piston that actuates a valve member. To compensate for leakage in the coupling chamber that is at high pressure, a filling valve is provided. The filling valve is disposed between the step-up piston and the piezoelectric actuator. Upon each return stroke of the piezoelectric actuator, the step-up piston follows the piezoelectric actuator with a time lag, so that the filling valve opens briefly and allows filling of the coupling chamber. The valves intended for use in fuel injection systems for internal combustion engines of motor vehicles.

Abstract: An electromechanical brake for motor vehicles such as passenger vehicles, has a member that can be electromotively moved in two directions, longitudinally speaking, in order to press at least one brake lining against a friction element in an application stroke and in order to release the brake lining in a restoring stroke. In addition, a clutch is provided which can be actuated by the longitudinally movable member and which effectively disengages the longitudinally movable member from the electric drive motor when a permissible restoring stroke is exceeded. This prevents a mechanical failure or damage to the brake in the event of a malfunction of this kind.

Abstract: A gear pump has a gear wheel with teeth on an outer circumference and a second gear ring with teeth on the inside surface. The gear ring is guided in a circular-cylindrical recess of a housing and together with the gear wheel, each rotates about their own axis which are offset from one another.
