Abstract

PURPOSE: To obtain a compact nonskid device that can change over a connecting condition between a master cylinder connecting port and a rear wheel wheel cylinder connecting port as desired in response to the case of the normalcy and failure of the oil pressure of a pump.
CONSTITUTION: An oil pressure system nonskid device is arranged to ensure that master cylinder oil pressure from a port 21 is introduced to a rear wheel wheel cylinder connecting port 26 through a check valve 31 opened by means of a piston 28 responding to pump oil pressure from a port 14 in response to a spool 15 operated by said pump oil pressure. In this case, a valve gear, which works so as to directly communicate the ports 21, 26 when pump oil pressure fails, is constituted by a valve hole 23, to which said port 26 is opened, a first valve body 25 energized by means of a spring 24 so as to block the valve hole 23 and a second valve body 27, which is mounted to said spool 15 and blocks an opening at the other end of the valve hole 23 when the spool 15 opens the valve body 25.
