摘要

Double-circuit hydraulic system for controlling consumers of mobile equipment such as track equipment comprises two circuits (2, 4) interconnected by an interconnecting valve arrangement (38) having two valve devices. Each valve device is assigned to one of the circuits and controls the connection to the other circuit as a function of load pressure and pump pressure. The connection of the line sections guiding the load pressure is designed so that the load pressure from the other circuit is not registered in the assigned circuit. Preferred Features: The interconnecting valve arrangement is housed in an intermediate plate (36) of a valve block.
