A receiver-tank is provided with a vertical tank main body 140. An inlet 131 and an outlet 132 are provided in an inlet-and-outlet forming member 150 as a bottom wall of the tank main body 140. A desiccant-filled-layer 135 as a flow-resistance layer is provided in a lower part of the tank main body

A receiver-tank is provided with a vertical tank main body 140. An inlet 131 and an outlet 132 are provided in an inlet-and-outlet forming member 150 as a bottom wall of the tank main body 140. A desiccant-filled-layer 135 as a flow-resistance layer is provided in a lower part of the tank main body 140, and an upper space is formed above the desiccant-filled-layer 135. A suction pipe 133 is provided in the tank main body 140 with the lower end connected with the outlet 132 and the upper end opened toward the upper space. When the refrigerant introduced into the tank main body 140 from the inlet port 131 goes up through the desiccant-filled-layer 135, the flow velocity decreases, and liquid-stagnation R is quietly created bin the upper space. The liquefied refrigerant of this liquid-stagnation R flows out of the outlet 132 through the suction pipe 133. Thereby, the stable liquid refrigerant can be supplied.

1. A receiver-tank for use in a refrigeration cycle, wherein a condensed refrigerant is introduced into said receiver-tank and accumulated therein and only a liquefied refrigerant flows out of said receiver-tank, said receiver-tank comprising:a tank main body having a refrigerant inlet and a refrigerant outlet each provided in a bottom wall of said tank main body; a flow-resistance layer for reducing a flow velocity of a refrigerant passing through said flow-resistance layer, said flow-resistance layer being provided in said tank main body such that an upper space is formed above said flow-resistance layer; and a suction pipe provided in said tank main body, said suction pipe having an upper end opened toward said upper space and a lower end communicated with said refrigerant outlet, whereby a refrigerant introduced into said tank main body via said refrigerant inlet passes through said flow-resistance layer upward to cause liquid stagnation of a liquefied refrigerant in said upper space, and the liquefied refrigerant flows out of said refrigerant outlet via said suction pipe.
