Abstract
A pressure control unit, in particular for pressure-fluid-actuatable dual-circuit brake systems of automotive vehicles, comprises a housing, a regulating device connected between an inlet and an outlet of a first brake circuit and actuated by an element applicable by a control force. A by-pass for bypassing the regulating device which is controlled by a locking piston acted upon by a second brake circuit. In order to accomplish a small overall length, low-priced manufacture and great functional reliability, the locking piston does not act directly on the regulating device.
