Abstract:
1. A solenoid-valve unit for an electropneumatic controller, comprising: a common valve-housing bottom having compressed-air bores; solenoid valves including solenoids and displaceable magnet armatures; at least one pressure sensor for measuring at least one pneumatic pressure, the at least one pressure sensor being disposed in the common valve-housing bottom and in communication with at least one of the compressed-air bores; first electrical leads for the solenoids; second electrical leads for the at least one pressure sensor, the solenoids being disposed outside of the common valve-housing bottom and the first and second electrical leads being routed to a common electrical interface; a control block fastened sealingly on the valve-housing bottom, the control block configured to receive the solenoids and the first and second-electrical leads between the electrical interface, the solenoids and the at least one pressure sensor; and a lead frame, at least a part of the lead frame including the first and second electrical leads, the control block being injection-molded around the lead frame and the solenoids.
