Claims

[Scope of utility model registration request]

a pilot valve that generates a predetermined pressure difference between the first and second pilot paths; When a predetermined pressure difference occurs between the pilot passages, the pressure difference acts to direct the inflow passage to the first or second
a first switching valve that connects the second or first load path to the outflow path and connects the inlet path and the discharge path in a neutral position and branches from the first and second load paths; When a predetermined pressure difference is generated between the first and second pilot paths by the operation of the pilot valve, the first or second branch path is actuated by the pressure difference. a second switching valve that connects a second branch path to the introduction path;
a pressure control valve that is interposed in a connection path that connects the inflow path and the outflow path and compensates for the differential pressure between the inflow path and the load path connected thereto according to the fluid pressure applied through the introduction path; and a third branch path that branches off from the introduction path and can be connected to a brake device.
