Abstract

Automatic valve arrangement for the automatic successive control of at least two valves that influence the supply of pressure medium to at least one consuming system depending on the pressure drop in front of a check valve provided between a transport pump with stroke piston adjustable by system pressure and automatic valve, the control operation can be caused by at least one sensor, exposed to the system pressure, with a control slide that can be moved against the spring effect by means of a pressure exposed to the system pressure, through the path of displacement of the control slide, characterized in that the path for the perception of pressure is the path for control.
