To provide a reversible gas-liquid separator suitable for miniaturization and cost reduction.
A gas-liquid separator 1A includes: a first pipe line 3A, a second pipe line 3B and a gas outlet pipe 4 as three pipe lines extended from the external part to the internal part of a closed container 2. A guide member 5 arranged in the closed container 2 forms an inflow space 11 between an upper cover 21 and the guide member and forms a flow passage 15 for causing bilayer flow F to pass between the inner circumferential surface of a cylindrical part 22 and the guide member. The first pipe line 3A and the second pipe line 3B are configured such that, even when either side of the first pipe line 3A and the second pipe line 3B causes gas-liquid two phase fluid to flow into the internal part of the closed container 2, the other side makes liquid in a reservoir 13 flow out to the external part of the closed container 2. Accordingly, the gas-liquid two phase fluid can be efficiently separated into gas and liquid, one side of the first pipe line and the second pipe line functions as an inflow pipe and the other side of these pipe lines functions as an outlet pipe, and a bidirectional fashion can be achieved at a small size and at a low cost.
