| The invention relates to a control element that realizes controlling functions in a small space and with a low consumption of energy whereby being able to absorb high levels of stress. The inventive passive control element comprises a housing (1) that encloses a sealed, fluid-filled clean space (2). All the elements located inside the clean space are protected from soiling. The control element function is realized by means of two force elements consisting of a force introducing element (4) and of a force take-over element (21), whereby both force elements can also be joined as one. Different controlling states are distinguished by different force conveyance possibilities between the force introducing element and the force take-over element. In controlling states, the free-running state and the coupled state are differentiated in that during the coupled state, a transmission of force from the force introducing element to the force take-over element ensues. The invention is particularly advantageous in that a change in the controlling states ensues without a transmission of force, and thus without a transmission of energy, from the controlling mechanism to the force elements. | ||||||

| 245 | Method and apparatus for identifying and eliminating vibration symptoms in hydraulic clutch actuators | EP02258284.5 | 2002-12-02 | EP1319847A3 | 2004-08-25 | Vennefron, Arlan; Hu, Jiamu |
The present invention provides a method and apparatus for identifying and eliminating vibration in a hydraulic clutch actuator. The vibration is identified (40) by using transducers to characterise the vibrational characteristics of a power train of a vehicle. That characterisation is used to program a shaker (71) on a test bed to replicate the vibrations on the vehicle in a hydraulic clutch actuator. Different hydraulic dampers are connected (48) with the clutch actuator on the test bed to reduce the vibration and the most satisfactory damper is chosen (54). The preferred apparatus of the present invention includes a two piece diaphragm type hydraulic damper (34) which may be opened so as to insert different damping diaphragms (97,98) for testing. |

A hydropneumatic positioning device comprises a tubular container (10). A hollow piston rod (18) is guided through one end of the tubular container (10). A piston (22) is connected with the piston rod (18) within a cavity (12) of the tubular container. The piston (22) divides the cavity (12) into two working chambers (12A,12B). The working chambers (12A,12B) contain a liquid. Adjacent one of the working chambers (12B), namely the working chamber remote from the piston rod (18), a compensating chamber (26) is provided. This compensating chamber (26) contains a pressurized gas and is separated from the adjacent working chamber by a floating separating wall (28). A flow passage (24A to 24E) extends through the piston (22) between the two working chambers (12A,12B). A valve (30) is allocated to the flow passage (24A to 24E). The valve (30) can be opened by an actuating rod (32) extending through an axial bore (34) of the hollow piston rod (18). The actuating rod (32) extends beyond an outer end of the piston rod (18). An actuating signal transformer (11) is fastened to the outer end of the piston rod (18).

| In a device for fastening perforating rules or blades on rolls (perforating cylinders) in printing machines, the perforating cylinder (26) has at least one receiver groove (25) for a perforating rule (11) in which a clamping strip (10) provided with hydraulic clamping devices can be inserted. Said clamping devices press the perforating rule into frictional engagement with a cheek of the receiver groove. The clamping strip (10) constitutes the cylinder housing for a plurality of pressure pistons (13) which form the movable boundaries of intercommunicating pressure chambers (13') completely filled with a pressure-transmitting medium. The volume occupied by the pressure-transmitting medium can be decreased and subsequently increased by means of a pressure regulator (16). The pressure-transmitting medium used is a thermoplastic which is introduced into the pressure chambers (13', 14) of the clamping strip (10) in the liquid state and hardens after filling to a flexible body. | ||||||
