<P>PROBLEM TO BE SOLVED: To provide a construction of a sub-strainer capable of smoothly supplying oil from valves while allowing capture of a foreign substance in connection with an oil stream from valves and capable of effectively preventing an invasion of a foreign substance concerning the oil stream. <P>SOLUTION: The sub-strainer 3 and a solenoid valve 4 are provided in an oil path 2 and by a model change of the solenoid valve, oil can be derived in the regular direction from the solenoid valve while oil is introduced from a reverse direction to the solenoid valve. A first mesh screen 31 and a second mesh screen 32 are provided on the sub-strainer, and when oil is introduced in the regular direction, oil is alienated from the first mesh screen, while, when oil is introduced from the reverse direction, oil is displaced in a sealing direction to the first mesh screen. Mesh parts 312, 322 of like-minded parts of both mesh screen overlap each other and when the second mesh screen closely contacts the first mesh screen, each overlaps in the state of displacement. <P>COPYRIGHT: (C)2009,JPO&INPIT |
