ABSTRACT:
An electropneumatic regulating valve for an air brake system of a motor vehicle, with a valve seat assembly which switches compressed air flow between at least one external brake line connection, a feed pressure connection, and a venting port, the valve seat assembly including a coaxial valve seat assembly with external and internal valve seats and a pot-like sealing cup with a coaxial passage. A ring-shaped, surface of the sealing cup seals between the exterior and interior valve seats. The opposing face of the ring-shaped surface has two coaxial sealing lip segments projecting away from the ring-shaped surface and forming an annular space therebetween. The sealing cup includes a reinforcing insert with a U-shaped cross-section located in the annular space which reinforces the ring-shaped surface and the sealing lip segments. The insert also has a molded-on shoulder which reinforces the inside radial area of the sealing area.
