Abstract

PURPOSE:To enable a releasing of the brake without applying any compressed air by connecting a hydraulic chamber in which a piston rod is extended or retracted with one of the hydraulic chambers of the cylinder divided by a piston. CONSTITUTION:When the compressed air is discharged from the operating fluid chamber C, the piston 2 is pushed in a leftward direction by the force of a spring. Since the control valve 8 between the hydraulic chamber B and the hydraulic chamber A is closed, the rod 7 is moved in a leftward direction and thereby the brake is applied. When the compressed air could not be fed due to some reasons, a brake releasing instruction is applied to the control valve 8. And the hydraulic liquid chamber B is communicated with the hydraulic liquid chamber A, the operating rod 7 is moved in a rightward direction and then the brake can be released.
