Patent number: 9897219Abstract: The pressure reduction valve includes: a cylindrical portion, a piston and a spring. The cylindrical portion includes an inlet communicating with the primary side flow path and an outlet communicating with the secondary side flow path. The piston fitted into the cylindrical portion is slidable along an axis direction of the cylindrical portion within the cylindrical portion, and defines, within the cylindrical portion, a space communicating with the inlet and the outlet. The spring applies, to the piston, a force acting toward the space. The outlet is displaced in one direction from the center of the piston when seen in the axis direction. The force applied to the piston by the spring is distributed so as to deviate from the center of the piston to the side of the outlet.Type: GrantFiled: October 29, 2015Date of Patent: February 20, 2018Assignees: Toyota Jidosha Kabushiki Kaisha, JTEKT CorporationInventors: Norihiko Saito, Sogo Goto, Masaaki Kondo, Akira Yamashita, Eiji Okawachi, Munetoshi Kuroyanagi, Toshikatsu Kubo, Takashi Iwaguchi

Patent number: 9562619Abstract: A safety valve includes: a valve element; a valve seat that has a gas release hole from which a gas is released and a protrusion that protrudes towards the valve element; and a meltable body that is made of a material capable of being melt at an abnormal high temperature. At a temperature other than the abnormal high temperature, the meltable body limits displacement of the valve element to thereby prevent inflow of the gas towards the gas release hole. At the abnormal high temperature, the meltable body is melt, thereby the valve element is displaced and the gas is released from the gas release hole.Type: GrantFiled: February 27, 2015Date of Patent: February 7, 2017Assignee: Toyota Jidosha Kabushiki KaishaInventors: Makoto Kojima, Sogo Goto, Takao Fukunaga
