Patent number: 11892109Abstract: When a pipe is inserted into a connector main body of a quick connector, first leg parts of a retainer are deformed and expanded by pressing force in the axial direction on tapered surfaces of the first leg parts caused by an annular protrusion of the pipe, and the annular protrusion of the pipe can pass through the first leg parts in the insertion direction. When the pipe releases from the normal position, the retainer moves in a prescribed direction from a standard position, the first leg parts make contact with a first guide of the connector main body, and the first leg parts are deformed so as to expand, and due to the deformation and expansion of the first leg parts the annular protrusion of the pipe can pass through the first leg parts in the release direction.Type: GrantFiled: October 8, 2021Date of Patent: February 6, 2024Assignee: Sumitomo Riko Company LimitedInventors: Ryousuke Kanegae, Yorihiro Takimoto, Yoshitsugu Imanishi

Patent number: 11536405Abstract: A connector includes: a tube body formed in a tubular shape having a first opening and a second opening at both ends thereof, a first opening side of the tube body being connectable to an end of a first pipe, a second opening side of the tube body being connectable to an end of a second pipe, the tube body allowing a fluid to flow therethrough between the first opening and the second opening; a temperature detection element embedded in a tubular part of the tube body and configured to detect a temperature of the fluid flowing through the tube body; and a terminal electrically connected to the temperature detection element and exposed to outside of the tube body.Type: GrantFiled: April 23, 2020Date of Patent: December 27, 2022Assignee: SUMITOMO RIKO COMPANY LIMITEDInventors: Yorihiro Takimoto, Yoshiki Kodaka, Ryousuke Kanegae, Makoto Ito

Patent number: 11536413Abstract: A connector that is in a fuel supply system capable of supplying a high-pressure fuel, and may reduce pulsation in a low-pressure pipe with a simple structure and extend the life of a mold is provided. A valve of the connector includes a valve seat contact surface and a tapering through hole. The valve seat contact surface axially separates from an annular valve seat and forms a forward-direction flow path due to pressure of the low-pressure fuel when the high-pressure fuel does not flow in reverse, and may come into contact with the annular valve seat when the high-pressure fuel flows in reverse. The tapering through hole is formed farther radially inward than the valve seat contact surface, forms an orifice flow path having a smaller cross-sectional area than the forward-direction flow path, and allows a reverse flow of the high-pressure fuel when the high-pressure fuel flows in reverse.Type: GrantFiled: June 8, 2021Date of Patent: December 27, 2022Assignee: Sumitomo Riko Company LimitedInventors: Ryousuke Kanegae, Ryuji Shibata, Yorihiro Takimoto, Yoshiki Kodaka, Ryoya Kawai

Patent number: 11378212Abstract: A pair of first leg portions of a retainer have first taper surfaces at distal end sides on surfaces on the side to which a first pipe is to be inserted. The first taper surfaces cause the retainer to move from an initial position to an insertion position by an axial-direction pressing force from an annular protrusion, during a period until the first pipe is inserted to a regular position. During the period until the first pipe is inserted to the regular position, a pair of second leg portions restrict the retainer from moving from the initial position to a confirmation position. In a state in which the first pipe is inserted to the regular position, the pair of second leg portions allow the retainer to move from the initial position to the confirmation position.Type: GrantFiled: April 27, 2020Date of Patent: July 5, 2022Assignee: Sumitomo Riko Company LimitedInventors: Ryousuke Kanegae, Kazushige Sakazaki, Makoto Ito

Patent number: 10502354Abstract: A quick connector includes paired first legs having a first push-in inhibiting protrusion, and paired second legs having a second push-in inhibiting protrusion. Although the first push-in inhibiting protrusions inhibit the push-in movements of a retainer in a state before a pipe is inserted, they do not inhibit the push-in movements of the retainer in such another state as the pipe is located at a midway position. The second push-in inhibiting protrusions inhibit the push-in movements of the retainer in the other state where the pipe is located at the midway position.Type: GrantFiled: May 2, 2017Date of Patent: December 10, 2019Assignee: Sumitomo Riko Company LimitedInventors: Hideo Terada, Ryousuke Kanegae, Kazuki Hatanaka

Patent number: 10047881Abstract: A fuel hose is provided, which includes an inner tube including a rubber layer and a rubber layer, a resin layer provided around an outer periphery of the inner tube and comprising a thermoplastic resin as a major component, and an outer tube provided around an outer periphery of the resin layer and including a reinforcement thread layer and a rubber layer. The inner tube of the fuel hose has a dynamic loss (Tan ?) of 0.3 to 1.2. The fuel hose has an outer diameter change ratio of not greater than 10% and a volume change ratio of not less than 15% when the internal pressure of the hose is increased by 1 MPa. The fuel hose is less costly, and has a fuel permeation resistance (fuel barrier property) as well as a pulsation suppressing property.Type: GrantFiled: November 3, 2016Date of Patent: August 14, 2018Assignee: SUMITOMO RIKO COMPANY LIMITEDInventors: Ryo Hirai, Yoshiki Kodaka, Kazuki Hatanaka, Ryousuke Kanegae
