Patent number: 6454070Abstract: A limiter plug and a drain plug are juxtaposed in a valve block. The limiter plug is provided with a thermo-switch of which operation, when a predetermined temperature is reached, opens a communication passage for drainage by means of a limiter pin. The drain plug is provided with a drain pin for draining a high-pressure oil in conjunction with the drainage action of the limit pin induced by the thermo-switch so that, when the predetermined temperature is reached, it substantially nullifies the torque for switching from 4 wheel-drive to 2 wheel-drive. In the status of no operation of the thermo-switch, the drain pin when a predetermined torque is reached, gradually opens the drain hole while catching a balance, to limit the torque to a predetermined value.Type: GrantFiled: May 15, 2000Date of Patent: September 24, 2002Assignees: Fujiunivance Co., Nissan Motor Co., Ltd.Inventors: Hiroyuki Nakano, Tadahiko Kato, Akira Nakabayashi, Toshiharu Takasaki, Hirotaka Kusukawa, Shigeo Murata
