The sound insulator is located in the valve. A housing (10) has pref. four flow channels (3), located at right-angles to a ventilation bore (1), which opens into a deflection chamber (2). The channels are surrounded by a damper ring (4), and the ring is secured in position relative to the channels by guide ribs (6). Ring gaps (5) between the ribs open into a ring chamber (7), which is connected to the atmosphere by a ring (9) with bores (8). The damper ring and/or bore ring consist of a sound-absorbent material. |
