Abstract
Abstract A stabilizer is disclosed, as for use at the intake to a fluid pump, comprising a tank for containing a reservoir of liquid for supplying the pump. Extending from and above the tank, a tube provides a dome to confine a volume of gas to dampen pulsations created by the pump. The gaseous phase (vapor) in the dome is maintained in the tank by a heater mounted on the dome in such a manner as to provide heat somewhat related to the need for increasing the volume of the gaseous phase. Increased heat transfer within the tank vaporizes liquid to increase the pressure of the gaseous phase resulting in an increase in volume.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
132 words
A fluid stabilizer adapted to pass a fluid stream and for absorbing pulsations created by abrupt changes in the fluid stream, comprising: a closed tank of generally cylindrical configuration for receiving and delivering said fluid stream; a tubular structure affixed somewhat concentrically in said tank defining at least one opening at the lower portion thereof for access by said fluid stream, said tubular structure extending out of said tank at the upper end of said tank to define an extending portion; closure means at the upper end of said tubular structure for defining a space to retain a gaseous volume for capacitive action with said fluid stream; and means affixed to the exterior of said extending portion for heating said space to retain a gaseous volume by vaporizing fluid from said stream.
Claim 2
Dependent Claim
132 words
A fluid stabilizer adapted to pass a fluid stream and for absorbing pulsations created by abrupt changes in the fluid stream, comprising: a closed tank of generally cylindrical configuration for receiving and delivering said fluid stream; a tubular structure affixed somewhat concentrically in said tank defining at least one opening at the lower portion thereof for access by said fluid stream, said tubular structure extending out of said tank at the upper end of said tank to define an extending portion; closure means at the upper end of said tubular structure for defining a space to retain a gaseous volume for capacitive action with said fluid stream; and means affixed to the exterior of said extending portion for heating said space to retain a gaseous volume by vaporizing fluid from said stream.
Claim 3
Dependent Claim
39 words
A fluid stabilizer according to claim 1 wherein said tank structure defines inlet and outlet ports for receiving and delivering said fluid stream and wherein said ports are tangentially located with reference to the cylindrical axis of said tank.
Claim 4
Dependent Claim
16 words
A fluid stabilizer according to claim 1 wherein said means for heating comprise an electrical means.
Claim 5
Dependent Claim
21 words
A fluid stabilizer according to claim 1 further including a fluid pump connected to said tank for carrying said fluid stream.
