Abstract:
1. A collector for the liquid phase of the working medium of an air-conditioning system, comprising a first and second connecting channel ( 4 , 5 ) which are guided at a diametral distance and parallel to one another vertically through a solid head-side connecting wall ( 28 ) of a cylindrical collecting container ( 3 ) provided for the vertical arrangement and comprising a piping system ( 6 ) connected to the second connecting channel ( 5 ) which is guided through the interior of the collecting container ( 3 ) and runs through its bottom region ( 10 ) with a deflection ( 7 , 70 ) and its end piece ( 9 ) discharges openly in the upper region ( 10 ) of the collecting container ( 3 ), wherein the piping system ( 6 , 66 ) in the area of the deflection ( 7 , 70 ) has at least one opening ( 11 , 72 ) for returning collected oil into the circuit of the air-conditioning system, characterised in that the outflow direction of the first connecting channel ( 4 ) is directed tangentially to the cylindrical inner surface ( 17 ) of the collecting container ( 3 ) and the open end piece ( 9 ) of the piping system ( 6 , 66 ) is arranged in the container axis so that the upper region ( 10 ) of the collecting container ( 3 ) forms a cyclone chamber.
