Abstract: The invention proposes a control device for multiway valves. It comprises two adjacently arranged solenoid means, which are respectively associated with a valve member to be driven. Each solenoid means comprises a coil. Outside the coils there is a yoke device for conduction of the magnetic fields, which are comprised in a yore part, which is associated with coils so that it may be pervaded by the magnetic fields of both coils. It is in this manner that an extremely compact design is rendered possible.

Abstract: A personal computer or equivalent is programmed to create a virtual operating unit for a robotic device (eg., a micro-processor controlled machine, conveyor, etc.). The actual operating unit, which plugs into the robotic device and controls it, includes a keypad and a display. When reprogramming the machine, the operating unit is unplugged and the computer is plugged in. The computer can be switched between two modes. In a programming mode, the computer is used to modify the program in the robotic device microprocessor. In an operating mode, the computer mimics the operating unit to test the newly-entered program. On the computer screen are generated a virtual display (the image of the actual display of the operating unit) and a map of the operating unit keypad. The technician observes the virtual display on the computer screen and enters commands, indirectly, through the computer's keyboard instead of through the actual operating unit keypad.

Abstract: A rotary-linear unit from whose front end the operative section of a output drive part projects. This output drive part is drivingly connected both with a linear drive and with an oscillating vane motor. The oscillating vane motor is associated with the rear end of the rotary-linear unit, the linear drive being arranged between the oscillating vane motor and the operative section of the output drive rod. This leads to an assembly which is extremely compact both in the axial direction and also in the radial direction.

Abstract: A spool valve having a valve housing with an internal spool receiving space, in which a valve spool is arranged. A plurality of sealing rings are arranged in axial sequence. Such sealing rings are retained in holding recesses, which are formed integrally with the valve housing. The valve housing is itself longitudinally divided and is composed of a plurality of housing parts which respectively constitute a wall section, extending for some distance in the peripheral direction, of the spool receiving space including the associated peripheral sections of the holding recesses. It is in this manner that the sealing rings may be inserted into the spool receiving space without any difficulty in the separated condition of the housing parts, whereafter the housing parts only have to be fitted together.

There is a provision for the possibility of axial motion of the inner sealing portion of the part, which is nearer to the valve spool, and furthermore a supporting and stiffening ring is present which is manufactured of a material harder than the material of the sealing body and preferably in a setting, as seen in the radial direction, outside the pivot axis with a coaxial arrangement in the sealing body.

Abstract: A housing for a drive cylinder which comprises an inner tube and an outer tube. The inner tube is a metal tube and is encircled by the outer tube consisting of synthetic resin material coaxially. In this manner it is possible to ensure a highly accurate cross section for the inner surface swept by the piston during operation. Simultaneously there is a large amount of freedom as regards any desired particular configuration of the external surface of the cylinder barrel.

Abstract: A linear drive which has a housing with a longitudinal slot. A drive part able to be longitudinally moved in the housing is connected by the aid of a link part, running in the longitudinal slot, with a guide part, which is guided for motion on a longitudinal guide arranged outside the housing. As a longitudinal guide a rod guide is provided, which has at least one guide rod adjacent to the housing and spaced from it radially. The guide rod is exposed along its guide stroke and has the guide part encircling it. There is therefore the possibility of accurate guiding of the moving unit without being affected by any tendency of the housing to splay outwards. The costs of manufacture are low.

Abstract: A fluid power valve unit with at least one electromagnetic actuating block on a valve block which is adapted to be connected with a connection block having fluid power ducts therein. This connection block has means for connection with further connection blocks and contains electrical power and/or control conductors therein, and a plug connecting device connected with these conductors is respectively arranged on those sides of the connection block, which come into engagement with corresponding sides on connection with further connection blocks. Furthermore there are electrical connecting devices for the conductors in the connection block and connection of same with electrical terminals of the at least one actuating block. It is thus possible to dispense with wiring using separate wire elements on the valve unit even in the case of a number of such units being plugged together in rows, the electrical connections also being automatically produced on plugging together.

Abstract: A linear drive comprising a drive member adapted to be reciprocated axially in a housing between two end positions. Opposite to the former there is a wall on at least one axial side. There are means to reduce the impact in the end position, such means having an annular lip. The lip is arranged on the drive member or on the wall and respectively faces the wall or the housing. The lip defines a damping space which is open on an impact side. If the drive member approaches one end position thereof, the damping space is occluded and reduced in volume so that some trapped fluid will escape via a relief opening so that there is a braked part of the stroke. Using simple means it is therefore possible to provide an extremely efficient fluid damping at the end position.

Abstract: A sealing ring for sealing off a joint between a fluid power line and a fluid power component to be connected therewith. At one axial side the sealing ring has two overpressure sealing lips arranged in a v configuration. At the opposite axial side a thrust portion is provided for cooperation with a gripping element. The thrust portion and an inner underpressure sealing portion provided thereon define a radially moving pivot ring. If the fluid power line is under vacuum, the pressure of the surroundings causes the pivot ring to be shifted inwards and the underpressure sealing portion is thrust sealingly against other surface of the fluid power line.

Abstract: A connection device for fluid conduits. An annular gripper member is arranged in a housing and has an axially sliding actuating part, on which a plurality of clamping elements are provided and between the clamping elements and the actuating part there are bending regions which allow rocking of the clamping elements.
