Relay valve, valve device, and vehicle associated therewith

A relay valve for a compressed air system, comprising:

• a housing comprising
• a pressure medium input configured to be connected to a pressure medium source,
• at least one pressure medium output configured to be connected to a consumer,
• at least one control input, and
• at least one purge (32) leading to atmosphere,
• a relay valve piston (14) which is arranged in the housing displaceably along a relay valve piston axis (16),
• a first sealing element (54) for sealing the relay valve piston (14) against the housing, wherein the first sealing element (54) is fixed to the housing,
• a second sealing element (56) for sealing the relay valve piston (14) against the housing, wherein the second sealing element (56) is fixedly arranged on the relay valve piston (14),
• an annular chamber (58) which is delimited by the first sealing element (54), the second sealing element (56), the relay valve piston (14) and the housing, and
• a connection of the annular chamber (58) to the atmosphere,
• wherein a part of a control chamber (22) connected to the control input is separated off as a damping volume (68), the control chamber (22) and the damping volume (68) being connected together via a choke (72), wherein the damping volume (68) is separated from the control chamber (22) via a diaphragm (70), and an opening in the diaphragm acts as the choke (72).
