Abstract (en)
[origin: EP0952354A2] The switch is used with hydraulic oil motors (10) and cylinders (11). A fast-traverse unit (32) is fitted in the pressure branch (5) and the return branch (2), which interrupts the two branches under control. Another oil motor (18) is driven by the same hydraulic circuit, and possibly used to drive an oil pump (19), may be included in the fast-traverse unit.
