摘要： A fluid circuit is provided for operation of multiple motors which comprises a pair of sources of high pressure fluid, two groups of directional control valves, each group containing at least two directional control valves separated by a signal block, each directional control valve operatively connected to deliver fluid to a fluid motor, one of said groups of valves being connected on opposite sides of a first signal block to each of said pumps through a pressure compensating valve, the other of said groups of valves being connected on opposite sides of a second signal block to each of said pumps through a pressure relieved inlet section, said second signal block in said other group including a pair of pressure operated spools regulating the flow of fluid from the two pumps to the directional control valves in said other group whereby the valves on either side of the second signal block can receive fluid from both pumps so long as only valves on one side or the other of the signal block are operative and receive fluid only from one pump at each side of the second block when valves on both sides are operative and shuttle valve means in connections between the signal blocks of each group whereby valves in each group may be simultaneously operated without starving the highest pressure motor.

摘要： The invention provides a valve construction comprising a pump control or regulating valve and a relief arrangement. The relief arrangement protects a pump from excessive pressure when the control or regulating valve is in the raising position and it protects a cylinder against shock loads, which occur during travel from one position to another under load, when the valve spool or valve spindle is in the neutral position or in the holding position. The device can be either part of a two-line or three-line system.
