Patent number: 4131438Abstract: A unitized apparatus with no moving parts capable of degassing the liquid flowing through it, forming a liquid seal and reservoir between the pressurization system and flowing liquid, and operating in an aircraft type varying "G" environment. Two cylindrical tanks are vertically disposed one within the other with a transfer tube forming the means of communication between their interiors. Liquid within the inner tank covers one end of the transfer tube both to form a liquid seal and to function as a limited reservoir. Gas introduced into the upper region of the inner tank pressurizes the system. The flowing liquid to be degassed is introduced tangentially between the tanks and exists through an opening in the outer tank near its lower end, producing a rotational flow and a centrifugal force to drive the gas bubbles inward toward gas traps located on the surface of the inner tank. Vortex flow within the trough-like gas traps captures the gas bubbles and confines them in the traps while the bubbles rise.Type: GrantFiled: November 4, 1977Date of Patent: December 26, 1978Assignee: The United States of America as represented by the Secretary of the Air ForceInventor: John S.
