Abstract: A tool for positioning or seating a ring seal within an annular groove of a seal fitting is disclosed. Generally, the ring seal seating tool of the present invention includes a first member for receiving a ring seal fitting to support such fitting during seating operations, a second member for at least aligning the ring seal with the ring seal groove of the ring seal fitting, and a third member for advancing the ring seal into the ring seal groove via the second member.

Abstract: Various types of valves are disclosed, as well as the use of the same in a reaction control system for space travel vehicle applications. Multiple functions are provided by one of these valve designs by providing multiple flowpaths through the valve. An inflow and outflow tube of this multifunctional valve are fluidly interconnected with first and second chambers, respectively, within the valve. These first and second chambers are isolated from each other by a barrier assembly which may be “removed” at the desired type by a barrier rupture assembly to provide one of the noted multiple flowpaths (i.e., the inflow tube, the first chamber, the second chamber, and the outflow tube). A separate service port is fluidly interconnected with each of the first and second chambers, and a separate service valve may be disposed in each of these service ports to provide additional flowpaths for the multifunctional valve.
