Load moment restricting valve connected to hydraulic force

摘要

The valve has a compartment (21) which is connected by directional valves (37) to a permanent hydraulic pressure source (33) in the form of a pump. The compartment containing the permanent power source (20) is joined by a reversing duct (30) connected to the hydraulic power source. A branch duct (27) secured by an overload valve (29) in the form of a return valve leads from the reversing duct into the valve chamber (21). A discharge duct (32) leads to the discharge connection (E).
