Abstract

A solenoid-valve unit for an electropneumatic controller, especially a pilot-control unit of an electropneumatic pressure modulator of a vehicle, includes a solenoid-valve unit having a valve-housing bottom with compressed-air bores, and solenoid valves having solenoids and displaceable magnet armatures. The solenoids are disposed outside of the valve-housing bottom. At least one pressure sensor for measuring pneumatic pressure in a compressed-air bore of the valve-housing bottom is placed in or on the valve-housing bottom. Electric leads to the solenoids and to the pressure sensor are routed to a common electrical interface.
