Claims

[Scope of utility model registration request]

A first oil passage 17 opened to the extension chamber 5 of the suspension cylinder 1, a port 34, and a second oil passage 33 opened to the contraction chamber 6 are formed in the valve body 10, and a second oil passage 33 is formed in the valve body 10 from the port 34. Road 33
A spool 22 that throttles the flow of pressure oil from the second oil passage 33 to the port 34 is slidably provided in the spool 22 due to the pressure difference between the chamber 21 and the port 34. A shaft 24 constituting an oil passage communicating between the passage 33 and the chamber 21 is inserted, and the shaft 24 is inserted into the chamber 2.
1 is connected to a first oil passage 17 through an orifice 16.
