Patent number: 11906096Abstract: A thermal expansion compensating device has a conduit with a first opening and a second opening for connection to a first pipe and a second pipe of a hot water system, respectively, the first and second pipes being formed by removing a section from a length of pipe of the hot water system. A pre-tensioning force is applied to the device to axially displace the first opening from the second opening until after connection of the openings of the pipes. A resiliently deformable pipe segment defines a portion of the conduit between the first opening and the second opening and is resiliently deformed to a tensioned position by the application of the pre-tensioning force. Once the hot water system is activated, the pipes axially thermally expand such that the first opening moves towards the second opening and the pipe segment moves from the tensioned position towards a rest position decreasing the stress on the device.Type: GrantFiled: October 27, 2021Date of Patent: February 20, 2024Assignee: IPEX TECHNOLOGIES INC.Inventors: Martin Kwan Yu Leung, Ivan Lee Stiehl

Patent number: 11460134Abstract: A connection to releasably connect and disconnect to a pipe to a fitting provides a pipe fitting body for receiving a pipe and a retaining ring located within the fitting body for retaining and releasing the pipe. The retaining ring has axially extending resilient retaining tabs, each of which has a radially inwardly extending portion for engaging the pipe, and, a radially outwardly extending portion which extends through corresponding radial openings in the fitting body. When the pipe is inserted into the fitting body to an inserted position and the retaining ring is in the first locked axial position, the radially inwardly extending portions engage and retain the pipe in the inserted position.Type: GrantFiled: October 20, 2020Date of Patent: October 4, 2022Assignee: IPEX TECHNOLOGIES INC.Inventors: Jis Simon, Filippo Martino, Ivan Lee Stiehl, James Bruce Anthony Campbell, Raymond George Puache, Paul Agapito, Qing Li

Patent number: 10088156Abstract: In a preferred embodiment, there is provided a water heater venting assembly for directing a combustion air and a flue gas between an outdoor atmosphere and a water heater, and which includes a generally hollow housing defining a combustion air aperture, a flue gas exhaust conduit disposed in the housing, and an adjustable inlet duct coupling assembly having a retention member for placement in the housing proximal to the aperture, a gasket for placement around an outer periphery of the aperture and a combustion air supply member. The retention member is for retaining the supply member in fluid sealing engagement with the gasket to effect fluid communication between the aperture and the supply member, and is sized to permit slidable movement of the supply member relative to the gasket.Type: GrantFiled: June 2, 2017Date of Patent: October 2, 2018Inventors: Martin Kwan Yu Leung, Ivan Lee Stiehl
