An antilock mechanism for use in a hydraulic brake system including a hydraulic pressure source (21), a wheel brake (23), and a drain channel (24), includes a flow control valve (25) and a drain valve (26) provided in the drain channel (24). The flow control valve (25) has an inlet port (34) connected with the hydraulic pressure source (21), a first outlet port (35) connected with the wheel brake (23), and a second outlet port (36) connected with the drain channel (24). A spool (41) is slidably inserted in the housing (27, 32). The spool comprises first axial conduit (42A) and a second axial conduit (42B) separated by a wall (57) having a fixed orifice (43) formed therein, and is biased by a return spring (49). The drain valve (26) is located adjacent the open end of the housing (27, 32) such that the second outlet port (36) of the flow control valve (25) and a valve member (56) of the drain valve (26) are connected straight. |
