PCT No. PCT/JP93/01399 Sec. 371 Date Aug. 17, 1994 Sec. 102(e) Date Jun. 28, 1994 PCT Filed Sep. 29, 1993 PCT Pub. No. WO94/10485 PCT Pub. Date May 11, 1994.(Object) The object is to provide a valve assembly which has a valve body or bodies whose sliding contact surface has a surface roughness not increasing during use, which is less likely to get damaged by the invasion of foreign matter, and which has an excellent mechanical strength such as creep resistance, so that the water cut-off property and operability are improved. (Structure) The valve assembly has a valve seat formed with inlet passages, a valve body kept in sliding contact with the valve seat and formed with flow passages. At least one of the valve seat and the valve body is formed of a resin composition comprising 35-90% by weight of a polycyanoarylether resin, and 10-65% by weight of carbon fiber having an average fiber diameter of not more than 8 mu m. Part of the carbon fiber may be replaced by a heat-resistant inorganic powdery filler having an average particle diameter of not more than 20 mu m. The heat-resistant inorganic powdery filler and the carbon fiber account for 10-65% by weight. |
