ーキ弁。The pressure chamber, which is slidably inserted into a hole drilled in the valve body and is connected to the brake cylinder, moves under the pressure of the brake pedal and the spool that is switchably connected to the hydraulic pump and the liquid tank. A plunger that operates the spool, a reaction member that receives the hydraulic pressure in the pressure chamber and transmits a reaction force according to the hydraulic pressure in the pressure chamber to the plunger, and a hydraulic pump that malfunctions and generates hydraulic pressure. In a hydraulic brake valve equipped with an emergency valve that can connect an accumulator to the pressure chamber when the pressure stops, the reaction force member is separate from the spool, and the spool and the reaction force are included in the valve body. Element,
A hydraulic brake valve, wherein the plungers are arranged in order to define the pressure chamber between the reaction member and the spool, and the reaction member is provided with an operating section for opening and closing the emergency valve.
