Abstract (en)
[origin: EP0909884A1] Main body (4) of the valve spool (3) has a guide rod on which the piston (5) is displaceable in the axial direction. When respective predetermined oil pressures are exceeded in the first (6) and second (7) operating chambers, a control orifice (10) in each chamber is exposed by means of the same control edge. Preferably the chambers are separated by a collar (19) on the valve spool.
