Claims

[Scope of utility model registration request]

(1) There is a cylindrical hollow part 2 on the central axis of the drip-proof valve body 1.
An oil inlet 3, an oil return port 4, a back pressure inlet 5, and a drip-proof valve outlet 6 communicating with the cylindrical hollow part 2 are provided.
In a drip-proof valve in which a piston valve 7 is inserted into the cylindrical hollow part 2 to open and close the drip-proof valve outlet 6 by operating based on the pressure difference between the pressure and the oil inlet 3 pressure, the piston valve on the back pressure inlet 5 side 7
A drip-proof valve characterized by having a sealing surface 8 protruding from the cylindrical hollow part 2 which exerts a sealing function by coming into contact with the flat surface of the valve.

(2) Instead of providing the sealing surface 8 on the drip-proof valve body 1, an inner cylinder 9 is inserted into the cylindrical hollow part 2 on the back pressure inlet 5 side of the piston valve 7, and the inner cylinder 9 and the piston valve 7 are connected. A sealing surface 8 is formed on the contact surface of the inner cylinder 9, and an O-ring 10 for sealing is provided at the contact area between the outer periphery of the inner cylinder 9 and the inner wall surface of the hollow cylindrical part 2. The drip-proof valve described in item 1.
