Abstract: A pressure regulating device has a pressure regulating valve with a valve casing and a regulating unit which is movable relative to the former. The regulating unit contains an actuation element which may be moved by a control pressure, and two first and second closing members, each spring-biased in a closed position, which may be switched by the actuation element. The connection between a primary port and a secondary port is controlled by the first closing member. Fixed immovably to the actuation element is a restrictor element which is moved into a restriction position when the actuation element is so positioned that the first closing member is normally moved into its closed position. If, because of a fault, the first closing member is not moved into the closed position, only a very small amount of pressure medium flows to the secondary port, so that consequential damage may be avoided.
