The invention relates to an expansion valve device for an expansion valve, in particular for a refrigeration system, preferably of a motor vehicle, comprising at least one sealing seat having a complete sealing seat-sealing surface, and a valve body (10) which is arranged on the sealing seat by means of a valve body-sealing surface (12) and which has a continuous main flow channel (110), wherein a coolant flow through the expansion valve device can be adjusted as a function of the position of the valve body (10) relative to the sealing seat sealing surface, and wherein at least one separate expansion zone (100) having at least two expansion channels (120, 122) embedded in the valve body sealing surface (12) is provided on the outside of the valve body (10) in such a way, the at least one expansion channel (120, 122) opens into the region of the opening (111) of the main flow channel (110).
本发明涉及一种用于膨胀阀、尤其用于优选机动车的制冷系统的膨胀阀装置,其包括:具有完整的密封座‑密封面的至少一个密封座以及利用阀体‑密封面(12)安置在该密封座上的阀体(10),所述阀体具有由此连续的主流动通道(110),其中根据阀体(10)相对于密封座‑密封面的位置能够调节穿过膨胀阀装置的冷却剂流,其中在阀体(10)外侧如此设定具有至少两个嵌入到阀体‑密封面(12)中的膨胀通道(120、122)的至少一个单独的膨胀区(100),使得至少一个膨胀通道(120、122)通入主流动通道(110)的开口(111)的区域中。
