Abstract (en)
[origin: EP1225337A2] The regulating device includes a control ring (2) movable in the housing (1) and provided with a bearing eye (6) which is mounted positively for swivel movement in a bearing (7) in the housing. A regulating lever (9) loaded by a resetting spring supported in the housing is mounted on the ring opposite the eye or on the eye opposite the ring and projects into a regulating chamber (10) where it adjoins a regulating piston (8). The piston is loaded on one side by a control pressure spring and on the other side by the control pressure which produces the regulating force on the pressure biased surface of the piston.
