PRESSURE FLUID FEEDING DEVICE

PURPOSE:To reduce the flow passage resistance and improve the reliability of an action by improving the feedback passage of a flow control valve which feeds back the excessive fluid to a tank side in said device which selectively feeds the pressure fluid discharged from multiple pumps to a fluid equipment. CONSTITUTION:When the feeding device is applied as a car power steering device 5, it is provided with a flow passage transfer mechanism 4 for selectively feeding the pressure oil discharged from the first and second pumps 1, 2 to the steering device 5. The transfer mechanism 4 is constituted with a flow passage transfer valve 12 which operates by detecting the pressure change of the pressure oil through a main passage 10 in response to the quantity of the load of the steering device 5 and a flow control valve 20 which releases a part of the flow flowing through the main passage 10 to a tank 3 side when the flow is a predetermined quantity or more. A valve hole 20a containing a spool 21 of the flow control valve 20 is provided with a feedback passage 28 made of a small diameter passage 28a and a nearly L-shaped hole 28b having a partially overlapped portion with the passage 28a.
