Abstract: A system may include a first member, a second member, a gasket and a pressurized fluid. The first member may include a first recess. The second member may include a second recess adjacently opposing the first recess. The second member may matingly engage the first member and may define a volume therebetween. The gasket may include a cross section having opposing first and second legs and a central portion disposed therebetween. The first leg may be received in the first recess. The second leg may be received in the second recess. The pressurized fluid may be disposed between the first and second legs and may urge the first and second legs into sealing engagement with the first and second recesses, respectively.

Abstract: A peristaltic pump assembly for moving a working fluid. The pump assembly includes an expandable fluid that changes in volume due to the presence of a magnetic and/or electric field. The pump assembly also includes a flexible member interposed between the working fluid and the expandable fluid. The pump assembly further includes a field generator operable to cause the expandable fluid to change in volume by applying the magnetic and/or electric field to the expandable fluid. This, in turn, moves the flexible member to increase the pressure of the working fluid to thereby move the working fluid.

Abstract: A valve for controlling a port in an air bag comprises a circular valve disk secured over the port. The disk has a circular mounting ring. Flexible valve elements extend radially inwardly from the ring. Each valve element is in the form of a wedge-shaped leaf with opposite side edges tapering radially inwardly to a point at the center of the ring. The valve is closed when the side edges of adjacent leaves are in contact. When the air bag deploys, the pressure of air in the bag flexes the leaves outwardly to open the valve.
