Claims

[Claims for Utility Model Registration] A main body 1 having an inlet 2 at one end and an outlet 3 at the other end in the middle of a return passage 31 to an oil tank 20.
The main body 1 includes: a cylindrical sliding valve body 4 whose inner diameter is set smaller than the inner diameter of the return flow path 31 and whose outer circumferential surface is in contact with the inner circumferential surface of the main body 1; , a spring 5 that normally biases the cylindrical sliding valve body 4 toward the inlet 2 side, and a base end 6a fixed to the outlet 3 side of the main body 1 and a distal end 6b facing the inlet 2 side. A rod-shaped valve seat in which the flow passage cross-sectional area between the cylindrical sliding valve body 4 and the tip 6b changes depending on the amount by which the tip 6b is inserted into and removed from the cylindrical sliding valve body 4. An oil return constant flow valve for a vehicle hydraulic lift, which houses a body 6.
