ABSTRACT:
In a pressure-regulating arrangement for the control pressure of a shifting arrangement of a change-speed transmission, a slide valve member is actuatable by an adjusting sleeve connected with a control member of a driving engine by way of a pressure member. A hydraulic damping device with two mutually relatively movable damping parts of the piston-cylinder-type construction is provided in which one damping part is adapted to be supported with respect to the housing and the other is actuatable by way of the pressure member and damping medium is thereby displaced against the action of a throttle. In order to improve the control behavior by decoupling the damping function from the control slide valve member, the damping device is arranged at the end face of the control slide valve member facing the pressure member and the damping part movable relative to the housing is connected with the pressure member while a damping chamber enclosed between the damping parts is connected by way of a relief valve with a space under atmospheric pressure.
