- the idle stroke ie during the adjustment stroke, only a small driving force is required to overcome the frictional forces and possibly weight resistances.
- the required drive energy corresponding to the pressure-effective areas in the drive unit decreases, for example, approximately 70% or more. This can also be determined by the choice of the pressure-effective piston surfaces, for example by varying the cross-section of the piston rod part 19 accordingly.
- the annular piston 7 strikes the end face of the piston slide 49, then it is also displaced in the longitudinal direction in the direction of stroke of the annular piston 7 in the wall 4 until it has the position shown in FIG has reached.
- the branch channel 43 is shut off from the Ringzyli ⁇ derraum 28 and via the longitudinal channel 53 in the spool 49 and its branch channel 54 to the channel 46 fluidly connected, whereby the annular cylinder chamber 28 is connected to a return line or vented.
- This return line or vent is again required in the opposite stroke direction for the supply of the pressure medium pressure, in particular for supply of compressed air.
- the fluid quantity displaced by the annular piston 7 is supplied via the longitudinal channel 53 in the piston valve 49, the branch channel 43 into the longitudinal channel 39 and via this via the transverse channel 40 and optionally via the channel 41 to the adjusting cylinder space 27 that during the idle stroke displaced by the annular piston 7 fluid quantity is not lost for the drive, but only the difference to the drive needs to be replaced, which vary depending on the setting of the adjusting 6 for Ringkolbe ⁇ 7 and thus the Einschraubpen of the piston rod part 16 in the piston rod part 19 can.
- piston rod parts 16, 19 are moved in the direction Y, then by a not shown control device for the fluid supply, in particular for the compressed air supply, the transverse channel 40 is acted upon by pressure medium pressure, in the position of the parts of FIG. 3 via the longitudinal channel 39 and the Channel 46 propagates via the longitudinal channel 53 in the annular cylinder space 28. Via the chamber channel 48, the pressure medium pressure also plants under the piston 50 bis in the chamber 45 continues and holds the spool 49 in its apparent from Fig. 3 position.
- the piston rod parts 16, 19 and the annular piston 7 and the adjusting piston 6 thereby move in the direction Y and pivot the toggle lever assembly 12 in the direction B, so that a clamping arm 15 or the like coupled thereto also moves in the direction B, ie pivots in the open position.
- the pivoting angle in direction A or B may be from 0 to 135 degrees or more.
- the parts then move until the brake piston 22 enters the brake chamber 25 and the sealing element 26 thereby shuts off the adjusting cylinder space 27. From there on, the fluid can only escape via a throttle bore (not shown) into the channel 41 or 40 and are fed to the return line.
- the fluid pressure for example compressed air pressure
- the fluid pressure propagates again via the transverse channel 40, the longitudinal channel 39 to the branch channel 43 and also via the channel section 44 and acts on the piston 50, whereupon the cycle described above can be repeated, since then the spool 49 again shifted in its apparent from Fig. 1 position in the X direction until it again shifts through the annular piston 7 in its apparent from Fig. 3 control position.
- the device according to the invention thus combines an energy-efficient drive with respect for the environment and the possibility of infinitely varying the stroke and thus the angle by which the parts driven by a crank lever joint can be moved from the outside without dismantling the device in both directions and in each case submit desired position while adjusting the interrogator, without this needed to be readjusted in the adjustment of Schwe ⁇ kwinkels.
- the reference numeral 60 denotes a transverse channel and the reference numerals 58 and 59 sealing elements for the pressure-tight passage of the rod 55.
- 61 is a plug through which the data which the sensor device 35 interrogates, are forwarded to a remote data collection point.
