Patent number: 11754195Abstract: A flow channel switching valve includes a valve stem that is attached to a ball valve member. The flow channel switching valve includes a potentiometer shaft that is press-fitted into an attachment hole provided in an end surface of the valve stem, and a potentiometer that detects a rotation angle of the potentiometer shaft around an axis. The potentiometer shaft has a small-diameter portion, a medium-diameter portion, and a large-diameter portion that are sequentially connected in a direction of the axis, and is supported rotatably around the axis in the attachment hole in an inserted state before being press-fitted into the attachment hole. The large-diameter portion is press-fitted into an upper end portion of the attachment hole.Type: GrantFiled: April 27, 2020Date of Patent: September 12, 2023Assignees: FUJIKOKI CORPORATION, DENSO CORPORATIONInventors: Daisuke Kondo, Kenichi Mochizuki, Masashi Yamashita, Takamitsu Mano

Patent number: 11073216Abstract: The present invention provides a flow channel switching valve with a reduced number of components as well as a reduced weight, and a method for assembling the same. A valve shaft adapted to be coupled to a valve element so as to transmit torque of a rotary drive portion to the valve element is inserted through a vertical through-hole, which penetrates through the valve element in the direction of the rotation axis O (i.e., vertical direction), and through a fit-insertion hole provided in a valve body. Then, a drive gear that forms the rotary drive portion is fixed to the upper coupling portion of the valve shaft protruding from the fit-insertion hole so that the valve shaft is rotatably supported with respect to the valve body.Type: GrantFiled: January 17, 2017Date of Patent: July 27, 2021Assignee: FUJIKOKI CORPORATIONInventors: Daisuke Kondo, Kenichi Mochizuki, Masashi Yamashita, Seiichi Hara, Takayuki Matsumoto
