Application/response load valve and brake operating unit

摘要

As for application/response load valve 21, the piston 40 which forms application/response load pressure by moving to axial direction the 2nd membrane board component 42 which is deflected the 1st membrane board component with the pressure of the output interior in order to output 41 which is deflected with the pressure of the pilot interior where the pneumatics which respond to the weight of the vehicle are introduced and application/response load pressure and, according to deflecting the 1st and 2nd membrane board component 41,42 and, from being pressured section 43b and the fixed part 43a which possess the being pressured aspect 43d which receives the pushing pressure due to deflecting the 2nd membrane board component 42 the extending coming out section which in diameter direction extending is put outAs it possesses with 43c, the power transmission component it is formed to another body from 43 which conveys the power which responds to the pushing pressure which in the being pressured aspect 43d is received from 2nd membrane board component 42 to piston 40 and block 25, it locks the peripheral section of 2nd membrane board component 42 in block, 25 the membrane board fixed component 45 which sets the area of the being pressured aspect 43d of power transmission component 43 and, it has.
