Abstract
PURPOSE: To prevent from exercising of an offset load on a piston and to protect against air leakage, by a method wherein a spring seat member, transferring a push force of a plunger to a spring, is supported by means of a plunger, and a direct transfer of a power between a piston and the spring seat member is eliminated.
CONSTITUTION: When a brake valve is applied to a 2-system brake valve and the like in which a fluid pressure property against a pedalling amount of a brake pedal 50 changes in two stages, it possesses feed discharge valve members 25 and 33, in a valve body 1, which open and close connection paths between feed ports 23, 40 and feed out ports 9, 17 and between the feed out ports 9, 17 and a discharge port 44. Furthermore, it is provided with pistons 7 and 13 which operate the feed discharge valve members 25 and 33. The piston 7 receives a push force of a plunger 55 driven by a brake pedal 50 from the above through the medium of srpings 60 and 64. A hooking part 59 is formed on a spring seat member 57 which is supported with the hooking part 59 matching a hole 58 in said plunger 55.
