摘要： A hydraulic pressure control valve has a piston slidably disposed in a bore of a housing and having a supplying pressure chamber therein which is communicated with a source of hydraulic pressure, an actuating pressure space defined in the bore for communicating with a pressure actuating means, the piston being exposed to the space at one side thereof and urged toward the space by a resilient means and having a supply opening for connecting said chamber with the space. A push rod is slidably disposed in the bore and operably connected to an operating means, a supply valve normally closing the supply opening and coaxially disposed in the piston. A normally open exhaust valve connects the actuating pressure space with a reservoir which supplies hydraulic fluid to the pressure source, the push rod being adapted to move toward the pressure space and the piston, when operated for closing the exhaust valve and further movement of the piston in the same direction, opening the supply valve.

摘要： A lining wear warning and adjusting device for a brake shoe lining. A rotatable member pivotally supported on a non-rotatable member so as to be engaged with a brake shoe carrying a brake lining is pivotally moved when the brake shoe is actuated; means arranged on the non-rotatable member in engagement with the rotatable member permits the movement of rotatable member during the braking operation and prevents the movement in the reverse direction when the brake is released; and an electric switch operative in response to a predetermined amount of relative movement between the rotatable and non-rotatable members closes a warning circuit, the relative movement between the rotatable and non-rotatable members being proportional to an amount of lining wear.
