Claims

[Scope of utility model registration request]

When the hydraulic piston moves, pressure oil is supplied to the central chamber in the separately placed potty according to the movement, and the spool in the same body is moved by the same pressure oil and reduces the back pressure by squeezing the oil in the central chamber. In a brake device that generates braking force by generating braking force, a piston with a roller is engaged with the spool, a cam is provided that engages with the roller of the piston, and the cam is moved in synchronization with the movement of the hydraulic piston, A spring that pushes the spool to the right is inserted into the left chamber of the spool, a choke is installed in the oil discharge pipe of the left chamber, and the left chamber and center chamber are connected to the spool at the beginning of the movement of the spool. A brake device for a hydraulic actuator characterized by having a small communicating hole.
