LOAD COMPENSATING VALVE AND BRAKE CONTROL DEVICE

摘要

A load compensating valve (21) is provided with a pressure regulating valve (50) capable of outputting a pressure corresponding to a load compensating pressure for a fully occupied vehicle, a pilot pressure sensor (52b), a solenoid valve (52) capable of supplying and discharging air and outputting the pressure, which is outputted from the pressure regulating valve (50), after regulating the pressure by supplying and discharging the pressure on the basis of a value detected by the pilot pressure sensor (52b), and an output valve (51) into which the pressure outputted from the solenoid valve (52) is inputted as a pilot pressure.  The output valve (51) has an empty-vehicle assuring spring (51d) for generating a pressure corresponding to a load compensating pressure for an empty vehicle and can output a pressure which is the sum of the pilot pressure and the pressure corresponding to the load compensating pressure for the empty vehicle caused by pressing force of the empty-vehicle assuring spring (51d) and which is outputted as a load compensating pressure corresponding to a value detected by a sensor for detecting the pressure in an air spring.
