Abstract
A deflector for use in an accumulator that provides a reservoir for the liquid-phase of a heat transfer medium circulating in a closed-loop air conditioning system is configured to prevent liquid phase medium from the supply pipe from entering the inlet area of the delivery pipe of the accumulator. The deflector has a recessed underside defined by a depending peripheral skirt having an outline that is closely spaced with respect to the peripheral wall of the accumulator to define therewith an annular gap. The upper wall of the deflector is positioned to be impinged by medium delivered from the supply pipe and is configured to distribute radially and impart rotation to the medium, thus enhancing the separation of the liquid phase along the accumulator peripheral wall, especially as the liquid and gaseous phase pass through the annular gap. The open inlet area of the delivery pipe is shielded within the recessed underside of the deflector.
