Patent number: 10363543Abstract: Fluid transport approaches are described that operate without the need for precise displacement of an actuator and with little or no sensing in the flow path. In certain implementations, a gas phase in a fluid reservoir is compressed by a pressure source such that releasing the pressure, such as by opening a valve to an intermediary conduit, displaces fluid to the intermediary chamber. Closing that fluid path and opening a different fluid path to a chamber at ambient temperature causes the fluid to be displaced to the chamber.Type: GrantFiled: April 19, 2016Date of Patent: July 30, 2019Assignee: GENERAL ELECTRIC COMPANYInventors: Philipp Lang, Ruben Julian Salvamoser, Victor Donald Samper, Christian Friedrich Peter Rensch
