Abstract (en)
[origin: EP0936179A1] The fork (G) can be swivelled and horizontally moved at least on a vertical axis (7) by means of magnet-operated directional servo valve spools (W1,W2) connected to a common pressure source (15) and if necessary computer-guided by hydraulic motors (H1,H2). A three-way pressure balance (D) positioned between the pressure source and the directional servo valve spools is controlled, upstream and downstream from the directional servo valve spools, by control pressures. At least the servo valve spool of the hydraulic motor has a zero position. The 3 way pressure balance is part of a circulating circuit (U) guided by the control of the further hydraulic motor.
