Abstract

The characterizing features of the invention are that a guide tube is provided which is disposed at least partially outside the evaporator plate and partially in the suction tube, is directly or indirectly retained on the evaporator and has a somewhat larger internal diameter than the external diameter of the throttle/capillary tube and a substantially smaller external diameter than that of the internal diameter of the suction tube; the throttle/capillary tube is inserted in the guide tube from outside and the compressor side end zone of the internal generated surface of the guide tube is connected pressure-tight inside a first longitudinal portion of the coolant supply line disposed in the guide tube to the associated zone of the external generated surface of the throttle/capillary tube and terminates in the guide tube; and the guide tube forms a second longitudinal portion of the coolant supply line having a cross-section widened in comparison with the capillary flow cross-section, and the inside space of the guide tube determined by the widened second longitudinal portion is connected to the inlet zone of the coolant duct.
