Abstract

A pressure control valve arrangement for controlling fluid pressure in a brake system of a vehicle includes two diaphragm valves and two electromagnetic control valves, activatable by an electronic control device, for the pilot control of the diaphragm valves. The two electromagnetic control valves have a double magnet with two magnet coils and magnet armatures and are actuatable by current being applied to the magnet coils. The housing has at least one pressure medium connection, connected to a service brake valve, for acting with pressure upon and/or relieving the pressure of the pressure control valve arrangement and at least one connection for connecting to a brake cylinder. A plane of symmetry of the mid-axes of the magnet coils of the double magnet is arranged in parallel and offset by the amount of an eccentricity, with respect to a mid-axis of the pressure medium connection.
