Claims

[Scope of utility model registration request]

An inlet connected to the hydraulic pressure generation chamber of the main actuating device, an outlet connected to the hydraulic pressure chamber of the driven device, an inner hole provided in communication with the inlet and the outlet, and an end of the inner hole on the outlet side. A hydraulic type comprising: a valve seat that has been diagnosed in the interior of the valve; a movable valve member disposed within the inner hole so as to be seated on the valve seat; and a valve spring that biases the movable valve member toward the valve seat. In the brake residual pressure valve device,
a recess connected to the outlet side of the inner hole; an auxiliary tool that can be fitted into the recess and whose inlet side end can come into contact with the movable valve member; a first engaging part that holds the auxiliary tool in a first position biased toward the exit; a second engaging part that holds the auxiliary tool in a second position biased toward the exit side;
The remainder of a hydraulic brake comprising a pressure receiving part provided on the auxiliary tool and generating an acting force that moves from a first position to a second position when the inlet side pressure is higher than the outlet side pressure by a predetermined value. Pressure valve device.
