Abstract
A relay valve apparatus having two relay valves are located in a single housing with their longitudinal axes parallel to one another. The two relay valves each include a double seat valve and a relay piston. The two relay valves are located one behind the other in the direction along their longitudinal axes so that the two double seat valves are located between the relay pistons. An outlet chamber of the first double seat valve and an outlet chamber of a second double seat valve empty into a common fluid pressure outlet leading to the atmosphere.
