Patent number: 11703018Abstract: An exhaust heat recovery device includes: a first flow path member; a second flow path member adjacent to the first flow path member, and which includes a heat exchange unit configured to perform heat exchange between exhaust gas flowing in the second flow path and a refrigerant; a valve mechanism configured to switch between opening and closing of the first flow path and the second flow path; and a drive unit which includes a drive shaft configured to rotate the rotation shaft portion. The second flow path member is inclined with respect to a flow direction of the exhaust gas in the first flow path, and the drive shaft extends toward the first flow path member and is connected to the rotation shaft portion in a region formed on a lateral side of the second flow path member when viewed in an axial direction of the drive shaft.Type: GrantFiled: May 26, 2021Date of Patent: July 18, 2023Assignee: Marelli CorporationInventors: Tooru Hisanaga, Naoharu Chiba, Shirou Nakajima

Patent number: 11434804Abstract: An exhaust purification device has a catalytic converter provided with: an outer cylinder welded at the upstream end portion to an exhaust gas inlet of an inlet-side flange and welded at the downstream end portion to an exhaust gas outlet of the outlet-side flange. An inner cylinder has an upstream end portion held by the upstream side portion of the outer cylinder with no gap and has a downstream end portion disposed at the downstream side of the outer cylinder with a gap, the inner cylinder housing a catalyst support. An opening end is formed at the downstream end portion of the inner cylinder with a gap with respect to the outer cylinder, and a gas layer is formed by the exhaust gas having entered from the exhaust gas inlet and convected to an upstream side between the outer cylinder and the inner cylinder.Type: GrantFiled: March 28, 2019Date of Patent: September 6, 2022Assignee: Marelli CorporationInventors: Tooru Hisanaga, Daisuke Sugaya, Tomoyuki Igarashi, Hitoshi Shimonosono

Patent number: 11105243Abstract: A housing has a heat exchange flow passage which branches from the main exhaust gas flow passage and converges to the main exhaust gas flow passage through the heat exchanger. The valve has a valve pipe constituting the main exhaust gas flow passage in the exhaust pipe and a valve body which rotates to contact a seat part downstream of the valve pipe in an exhaust gas flow direction such that the exhaust gas flows to the heat exchange flow passage. An out port of the heat exchange flow passage which converges to the main exhaust gas flow passage is disposed upstream of a downstream side distal end of the valve pipe in the exhaust gas flow direction, and the downstream side distal end of the valve pipe in the exhaust gas flow direction is disposed upstream of a downstream side distal end of the heat exchanger in the exhaust gas flow direction.Type: GrantFiled: March 28, 2019Date of Patent: August 31, 2021Assignee: Marelli CorporationInventors: Shirou Nakajima, Mizuki Hayashida, Hiroaki Masubuchi, Tooru Hisanaga, Katsufumi Inoue
