Abstract
A valve unit () for modulating pressure in a compressed air braking system includes a brake pressure input (), a brake pressure output (), and a purge output (), an inlet valve () and an outlet valve (), both configured as a diaphragm valve, and respective precontrol valves (), which are each configured as a 3/2-way solenoid valve. For effective sound damping of the compressed air emerging into the environment when the outlet valve () is open, the valve unit () at the purge output () has a silencer () with a largely cylindrical silencer housing () with an inlet opening (), a calming chamber (), a large outlet opening () and a silencer insert () arranged upstream of the outlet opening () inside the silencer housing (). The silencer is air-permeable and sound-deadening and attached to the base housing () with base walls ().
