Patent number: 8241013Abstract: Embodiments of the present invention are directed to devices and methods for propelling fluids that feature at least one first pump assembly having a primary pump, an accumulator pump, drive means, valve means and control means. The valve means moves between the first position and the second position as the accumulator pump and primary pump alternate between a loading movement and a pump movement. The control means is in signal communication with the accumulator pump, the primary pump and the valve means. The control means issues signal command to the accumulator pump to assume the loading movement and the pump movement and the primary pump to assume the loading movement and pump movement in coordination with the movement of the valve means such that fluids are propelled from the first outlet.Type: GrantFiled: October 24, 2006Date of Patent: August 14, 2012Assignee: Waters Technologies CorporationInventors: Mark W. Moeller, Daniel J. McCormick, Joseph A. Luongo

Patent number: 7955059Abstract: In various embodiments a fluid control device suitable for high pressure analytical instruments includes a housing having an interior surface with an end wall. The interior surface defines a chamber. A valve assembly disposed in the chamber controls the flow of fluid through the chamber. An end cap is disposed in the housing opposite the end wall to enclose the chamber. The end wall and end cap each have an opening to pass a fluid to the chamber or to remove a fluid from the chamber. The housing and end cap each has an abutment surface to receive the other abutment surface. At least one of the abutment surfaces has a plastic seal coating. A means of compression, such as a compression housing and compression sleeve, is included to engage the end cap to deform the plastic seal coating between the abutment surfaces and thereby seal the chamber.Type: GrantFiled: March 2, 2005Date of Patent: June 7, 2011Assignee: Waters Technologies CorporationInventors: Theodore D. Ciolkosz, Peter Kirby, Mark W. Moeller, Russell Keene, Daniel J. McCormick, Charles Murphy, Joseph A. Luongo, David R. Friswell, Theodore Dourdeville
