Pulsation Dampening Device For Super Critical Fluid Expansion Engine, Hydraulic Engine Or Pump In Cryogenic Service
US Patent:
4878350, Nov 7, 1989
Filed:
Mar 8, 1989
Appl. No.:
7/320346
Inventors:
Leif A. Ness - Macungie PA
Assignee:
Air Products and Chemicals, Inc. - Allentown PA
International Classification:
F17C 702
US Classification:
62 501
Abstract:
The present invention discloses a surge bottle or pulsation dampening device for cryogenic services which comprises three sections: a liquid sump section comprised of an enclosed area containing a volume of an incompressible fluid; a warm gas volume section comprised of an enclosed area containing a volume of a compressible warm gas; and a laminar flow section which connects and allows for communication between the liquid sump section and the warm gas volume section. The laminar flow section is comprised of a number of small bore, thin walled tubes which contain the incompressible fluid in the end connected to the liquid sump section and the compressible warm gas in the end connected to the warm gas volume section. The bore of the tubes in the laminar flow section are such that any movement of either the compressible warm gas or the incompressible fluid in the tubes would be laminar.
