Patent number: 8038119Abstract: A metering device has an actuating unit within a housing in which an actuator is inserted and a hydraulic compensating element. The hydraulic compensating element is connected to the actuator and can be filled with a fluid when subjected to pressure. A first end of the actuator is provided with a first end cap. The metering device further has a stop that is disposed on the housing in the form of a seat, faces the first end cap, and defines a stopping position for the first end cap. The stop maintains a maximum distance between a sealing element and the end cap, the distance being smaller than the actuator traveling distance such that the actuator stroke beyond the end cap is sufficient for opening the valve. The first end cap hits the stop when moving in the direction of the hydraulic compensating element such that the movement is blocked.Type: GrantFiled: September 10, 2004Date of Patent: October 18, 2011Assignee: Siemens AktiengesellschaftInventors: Georg Bachmaier, Bernhard Fischer, Bernhard Gottlieb, Andreas Kappel, Tim Schwebel

Patent number: 8004149Abstract: A motor which includes two drive elements, especially piezoelectric bending actuators, having effective directions that are perpendicular to each other. These actuators act upon a drive ring to thereby rotate a shaft. Two tension-compression bars, which are parallel to an effective direction, are connected to the drive ring, have respective joints at their ends and are connected to the ends of a diagonal bar, relative to which the ring can be displaced in the other effective direction. The diagonal bar itself can be displaced relative to fixing elements to an effective direction via a diagonal suspension. The drive is compact, having actuators that are non-radially hinged to the ring.Type: GrantFiled: April 23, 2008Date of Patent: August 23, 2011Inventors: Heinrich-Jochen Blume, Bernhard Gottlieb, Andreas Kappel, Robert Wolfgang Kissel, Karl-Heinz Mittenbühler, Tim Schwebel, Carsten Wallenhauer
