Abstract
In an accumulator, an oil collecting pipe is held in a sealed vessel with the lower end thereof closed, the pipe has a plurality of oil collecting apertures spaced in a vertical direction and a communication port for communicating with a discharge pipe. The communication port is disposed in the vicinity of the lowermost oil collecting aperture or to the downstream side of the aperture. Therefore, excessive liquid refrigerant flow from the accumulator is prevented even if a large amount of the liquid refrigerant resides in the sealed vessel.
