초록

A gas arrestor separates entrained gas from a liquid medium. The gas arrestor is a porous member, such as a woven mesh screen having pores of a size sufficiently small to enable liquid transport while inhibiting gas transport. Since the trapped gas has a tendency to accumulate on the porous member impeding continued liquid flow, a wick extends in an upstream direction from the porous member. When used in spacecraft to provide substantially gas-free liquid to a thruster, the gas arrestor is located between a tank of pressurized liquid propellant and a gas...

청구항

1. A gas arrestor for separating an entrained gas from a liquid, comprising:an inlet coupling a source of said liquid having an entrained gas component from a reservoir contained within said gas arrestor, a wall of said reservoir being formed from a first side of a porous member; said porous member having said first side and an opposing second side with pores extending therebetween, said pores of a size effective to enable the flow of said liquid from said first side to said second side by capillary action while inhibiting the flow of said entrained gas ...
