Solenoid controlled valve and antilock control apparatus using the same

摘要

A solenoid controlled valve 31 comprises a spool 33. One end side of the spool 33 is slidably inserted into a first fluid chamber 32a of a sleeve 32 in a fluid tight condition. The other end of the spool 33 is loosely inserted into a second fluid chamber 32b. The spool 33 with a stationary orifice 40 is provided in an inlet path 39 extending in axial direction. A spring 30 for urging the spool 33 and a movable core 34 fixed to the spool 33, a coil 36 are provided. When electric current is supplied to the coil 36, and the movable core 34 is attracted against the spring force and the spool 33 moves opposite to the urging direction of the spring 30, so that the external peripheral face 33a of the spool 33 closes the first port 38a and the second port 38b.
