摘要

The noise damper for the counter pole venting of magnetic valves, has a housing (20) with a spiral-shaped widening air guide. In the centre of this guide is an inlet aperture (17) for the air leaving the valve (1). On its periphery are outlet apertures (22) distributed around the circumference. The housing itself (20) has a cover wall (19) with an outer wall around it, and a dividing wall running spirally in the space enclosed by the outer wall and positioned vertically to the cover wall.
