Abstract
A gas dryer having a housing, an outlet chamber, a pressure relief space, and a connection connecting the outlet chamber to the pressure relief space. An outlet valve is located within the connection connecting the outlet chamber to the pressure relief space. A piston which actuates opening and closing of the outlet is subjected to pressure contained in a control chamber. This pressure urges the outlet valve into an open position. The gas dryer also has an auxiliary valve system which is located between the control chamber and the pressure relief space. The auxiliary valve system controls the flow of the pressure medium between the control chamber and the relief space.
