Abstract
A relay valve () for a compressed air system, has a housing, which has a pressure medium inlet that can be connected to a pressure medium source, at least one pressure medium outlet that can be connected to a consuming unit, at least one control inlet, and at least one vent () leading to atmosphere. The relay valve () furthermore has a relay valve piston (), which is arranged in the housing in such a way that the relay valve piston can be moved along a relay valve piston axis () and divides a control chamber () and a working chamber () from each other in the housing. The relay valve () has a damping volume (), which is pneumatically connected to the control chamber (), thereby advantageously enabling the oscillation capacity of the relay valve piston () to be reduced.
