Abstract

The controllable adjusting system (28) is controllable depending on the output signal of the measuring system. The clamping pressure exerted by the worm casing (22) against the conveying screw (14) is esp. proportional to the conveying pressure. A determination system is provided for determining the conveying pressure from the operating parameters of the drive system (16). The adjusting system (28) is controllable depending on the output signal of the determination system. The drive unit (16) and the adjusting system are respectively driven hydraulically.
