Abstract

PURPOSE: To decrease power loss in such a way that in an equipment to selectively feed discharging fluid by means of a plurality of pumps to a hydraulic machine, a variable orifice to limit pressurized fluidic flow rate is provided on a flow control valve to control fluidic feeding rate.
CONSTITUTION: When applied on an equipment in which pumps 1, 2 driven by a common engine are circulating and feeding working oil in a reservoir 3 through a flow control part 4 to a power steering gear 5, the flow control part 4 is constituted in such a way that a flow control valve 12 is installed on the downstream side of the connecting part of a subsidiary path 11 for a main path 10. The flow control valve 12 provides a spool 15 whereby when pressurized fluid grows to be more than the predetermined value, the control valve 12 is traveled to the right and a part of the pressured flued in the main path 10 is flowed through a drain path 25, etc. back to the reservoir 3. Besides, the flow control part 4 provides a variable orifice which includes a small diametral part 27 of the spool 15 to control pressurized fluidic flow rate in such a way that when the main path 10 is throttled said spool 15 is traveling to the right.
