Patent number: 10107279Abstract: The subject invention provides a fluid flow apparatus for transporting a fluid to inflate and deflate a device including a pumping device and a housing defining a chamber, an inlet port, a fill port, and an exhaust port. A seal member is movable between a seated position closing the exhaust port and an unseated position. A motor has a shaft rotating in each of a first and second rotational direction. A clutch is disengaged from the shaft as the shaft rotates in the first rotational direction and is engaged with and rotates with the shaft as the shaft rotates in the second rotational direction. A centrifugal member is mounted and rotates with the clutch when the shaft rotates in the second rotational direction and engages the seal member to move the seal member to the unseated position for permitting the fluid within the chamber to escape through the exhaust port.Type: GrantFiled: December 10, 2012Date of Patent: October 23, 2018Assignee: KONGSBERG AUTOMOTIVE ABInventors: Frank Dankbaar, Anders Grönhage

Patent number: 10107410Abstract: The subject invention provides a fluid routing device for directing the transportation of a fluid including a housing defining first and second corridors selectively fluidly coupled to one another, and a valve assembly capable of alternating between an open configuration fluidly coupling the first and second corridors and a closed configuration fluidly separating the first and second corridors. A shape memory alloy member alternates between a de-energized state and an energized state. A link is pivotably mounted to the housing and is coupled between the valve assembly and the shape memory alloy member. The link pivots between a first position when the shape memory alloy member is in the de-energized state and a second position when the shape memory alloy member is in the energized state which alternates the valve assembly between the closed configuration and the open configuration for selectively fluidly coupling the first and second corridors.Type: GrantFiled: March 6, 2013Date of Patent: October 23, 2018Assignee: KONGSBERG AUTOMOTIVE ABInventors: Frank Dankbaar, Anders Grönhage
