Precision High Pressure Control Assembly
US Patent:
5888050, Mar 30, 1999
Filed:
Aug 25, 1998
Appl. No.:
/139230
Inventors:
Wayne Fitzgerald - Oxford PA
Kenneth J. James - Newark DE
Brian J. Waibel - Newark DE

Assignee:
Supercritical Fluid Technologies, Inc. - Newark DE
International Classification:
F04B 4900
US Classification:
417 46
Abstract:
A precision high-pressure control assembly for supercritical fluids comprises a continuous flow system having a pressure control loop which includes a source of fluid communicating with a piston driven pump. A pressure sensor monitors the pressure of the supercritical fluid in the outlet line of the pump. A pressure controller has an input for receiving a signal relating to the pressure sent by the pressure sensor and the pressure controller yields an electronic output signal to an electropneumatic regulator. A source of air communicates with the electropneumatic regulator to provide pressurized regulated driver air directed to the pump. The electropneumatic regulator controls the regulated driver air pressure of the pump in accordance with the signal received from the pressure controller. The piston head of the pump is in a cryogenic chamber to minimize flash and cavitation.
