Patent number: 6561480Abstract: The present invention provides a motor-operated valve having no additional stopper for stopping the rotation of a rotor at fully open and closed states of the valve to allow a reduced number of parts of the valve and to prevent a noise otherwise generated by the abutment of the rotor against a stopper. The motor-operated valve includes a rotor 17 having a shaft 18 formed with an external thread 20. The motor-operated valve also includes a needle valve element 6 having a needle valve head 5 at one end portion thereof and an internal thread 16 engaging with the external thread 20 at another end portion. The valve element has a joining portion 14 for joining the valve head to the internal thread 20. The motor-operated valve also includes a main valve body 1 having a guide portion which stops the rotation of the valve element but allows the axial movement of the valve element.Type: GrantFiled: November 22, 2000Date of Patent: May 13, 2003Assignee: Kabushiki Kaisha Saginomiya SeisakushoInventors: Yasuo Komiya, Seiichi Nakano, Hideki Sekiguchi, Tokuji Yatsui
