摘要： A control device for the actuation of a hydraulic load, such as a disk brake, includes a cylinder with an outlet leading to the load, this outlet being separated from an adjoining cylinder chamber by a valve body provided with an elastically deformable peripheral skirt and with a capillary central passage. During the forward stroke of a piston acting upon an oil volume in the cylinder chamber under extraneous pressure, oil can flow around the valve body into the outlet to actuate the load. During the return stroke upon the release of the applied pressure, the deformable skirt blocks the peripheral path of the oil whereby the same can return to the cylinder chamber only through the capillary passage, at a reduced rate, the oil volume in the chamber being supplemented from an adjoining reservoir communicating therewith in the retracted piston position.
