ABSTRACT:
An antilock mechanism for use in a hydraulic brake system including a hydraulic pressure source, a wheel brake, and a drain channel, includes a flow control valve and a drain valve provided in the drain channel. The flow control valve has an inlet port connected with the hydraulic pressure source, a first outlet port connected with the wheel brake, and a second outlet port connected with the drain channel. A spool is slidably inserted in the housing. The spool comprises first axial conduit and a second axial conduit separated by a wall having a fixed orifice formed therein, and is biased by a return spring. The drain valve is located adjacent the open end of the housing such that the second outlet port of the flow control valve and a valve member of the drain valve are connected straight.
