Kind Code:

Abstract:
A strainer capable of preventing foreign matters from advancing into a control valve and manufacturable at low cost. The strainer (73) is installed in the strainer mounting part (81) of a valve body comprising a sleeve (62) having a port and the strainer mounting part (81) and a spool disposed in the sleeve (62) so as to be advanced and retreated. The strainer comprises engagement parts (m1) brought into contact with first contact portions (&epsiv 1) and (&epsiv 2) formed on the strainer mounting part (81) and contact parts brought into contact with second contact portions (&epsiv 3) and (&epsiv 4) formed on the strainer mounting part (81). Since the strainer comprises the engagement parts (m1) in contact with the first contact portions (&epsiv 1) and (&epsiv 2) and the contact parts in contact with the second contact portions (&epsiv 3) and (&epsiv 4), the sleeve (62) can be sufficiently brought into contact with the strainer (73) at the first and second contact portions (&epsiv 1) to (&epsiv 4).
