Definitions
- a continuation of the active design, in particular the pneumatic design, in a drive 60 with a spindle provides that an overpressure is built up to close the valve device 20 so that the piston pulls the spindle nut of the drive 60 in the direction of movement.
- the drive side 53 is then depressurized, so that the hydraulic pressure in the supply line 32 wants to drive the spindle in the direction of movement via the hydraulic cylinder. Due to self-locking, e.g. due to the thread pitch of the spindle, the actual movement of the spindle is only guaranteed by the motor.
