Title:
LOAD SENSING VALVE DEVICE
Document Type and Number:
Japanese Patent JP3307147
Kind Code:
B2
Abstract:
PURPOSE: To provide a device simple in structure and inexpensive capable of securing a sufficient braking effect of a rear brake device at the time of breakage of a disc spring on a load sensing valve device devised to control brake fluid pressure transmitted to a rear wheel brake device by detecting loading weight of a vehicle by sagging of the disc spring.
CONSTITUTION: A by-pass passage 96 capable of directly communicating an input port 14 and an output port 16 by by-passing a pressure regulating valve 50 is provided in a valve housing 12 of a load sensing valve 10, and the by-pass passage 96 is normally closed by a by-pass valve 100. At the time when a disc spring to detect a live load of a vehicle is broken, the substantially same brake fluid pressure is supplied to front and rear wheel brake devices 20, 24, and rear wheel braking force is secured while the input port 14 directly communicates with the outlet port 16 by opening the by-pass valve 100.
