20130015379 | FLUID-OPERATED ACTUATING DRIVE ON A VALVE - A fluid-operated actuating drive ( | 01-17-2013 |
20130009080 | FLUID-OPERATED ACTUATING DRIVE ON A VALVE - A fluid-operated actuating drive on a valve comprising a base unit ( | 01-10-2013 |
20120272840 | MACHINE PRESS - In a machine press having a lower and an upper tool carrier, a hydraulic drive acting on the upper tool carrier comprises at least one closed hydraulic drive system that can be switched between rapid motion and press motion, the drive system having at least one hydraulic cylinder piston unit. The hydraulic liquid of the at least one hydraulic drive system is stored in a pressure accumulator fanning the storage container, supplying the entire associated hydraulic drive system permanently with at least a base pressure above the ambient pressure. There is no hydraulic connection whatsoever between the working chamber on the piston rod side and the working chamber on the piston side of at least one hydraulic cylinder piston unit. The upper tool carrier is pre-stressed into the upper final position thereof by means of a spring unit. | 11-01-2012 |
20120214369 | WATER CRAFT - In a water craft having at least one hull and at least one drive motor, which has an operative drive connection via a drive train to a drive head comprising a propulsion means, the drive head is laterally pivotably mounted relative to the hull with respect to a steering axis. For the lateral adjustment of the drive head relative to the hull, at least one hydraulic steering cylinder is provided, which can be acted on by a hydraulic steering system comprising a hydraulic pump. A hydraulic system, which comprises a separate hydraulic unit and is intended to be used to act on a hydraulic load not serving to steer the water craft, can be coupled to the hydraulic steering system in order to effect an emergency steering function in the sense of acting on the hydraulic steering cylinder. | 08-23-2012 |
20100224059 | ELECTROHYDRAULIC BOOSTER - An electrohydraulic booster comprises an electromechanical transducer and a hydromechanical power stage which is connected to a pressurized medium supply and encompasses a cylinder and a piston that can be moved therein along the working axis. The electromechanical transducer acts on a spool valve which is associated with the hydromechanical power stage, is disposed at least in part inside the piston, is guided within a guiding bore in such a way as to be movable along the working axis, and has two first leading edges that cooperate with corresponding second leading edges located on the guiding bore in order to form a hydraulic sequential control. The guiding bore consists of two parts, i.e. a cylinder-mounted first section and a second section which can be moved along the working axis and comprises the second leading edges. | 09-09-2010 |
20100117015 | PIEZOELECTRIC VALVE - A piezoelectric valve having a housing is provided with an inner chamber, in which ends at least one nozzle communicating with an associated port for a medium and provided with a sealing seat having a seat face, a deformable piezoelectric bending element being received in the inner chamber of the housing in such a way that the nozzle can be closed by a portion of the bending element movable relative to the nozzle in response to deformation of the bending element, and the bending element being provided with padding of an elastically resilient material, at least in its region opposite the nozzle. This sealing seat is disposed at the end face of a nozzle insert, which is disposed to be displaceable substantially perpendicular to the seat face in a receptacle fixed to the housing, a thermally expandable compensating member acting between the receptacle and the associated nozzle insert. | 05-13-2010 |
