Valve esp. brake valve for brake unit of EBS system has membrane with peripheral sealing bead engaging over valve housing for pressure-proof seal of valve housing and appliance housing

摘要

The brake unit has a valve with valve housing sealed by a membrane against the actuator device (20). The membrane (26) has an O-ring-shaped bead (32) along its outer contour. When the membrane is fitted, the bead engages pressure-tight over the valve housing (4), and is located radially sealing between valve housing and appliance housing (5). The valve housing has a peripheral outward projecting flange (34), which engages pressure-proof over the membrane. Membrane and bead consists of an elastic material, esp. rubber.
