摘要： In a main valve having a solenoid pilot operated valve a movable core and a hollow plunger (17) are movably received in a sleeve (16) extending from a pressure control chamber (14) through an electromagnetic coil (15). Said plunger (17) is structurally separated from a main valve member (5). A shaft (18) is slidably received in said plunger (17). One end of said shaft (18) carries a pilot valve member (19). A spring (20) engages at said plunger (17) and said shaft (18) such that the free end of said shaft (18) projects a predetermined length beyond an end face of the plunger (17). As long as said coil (15) is de-energised, said spring (20) separates said pilot valve member (19) from a pilot valve seat (9). As soon as said coil (15) is energised the plunger (17) is attracted to the core, the shaft (18) is displaced in relation to said plunger (17), and the pilot valve member (19) projecting from the lower end of said plunger (17) closes said pilot valve seat (9). Due to a then developing pressure difference said main valve is closed and kept in a closed state.
摘要翻译：在具有螺线管先导式操作阀的主阀中，可移动芯和中空柱塞（17）可移动地容纳在从压力控制室（14）穿过电磁线圈（15）延伸的套筒（16）中。所述柱塞（17）在结构上与主阀构件（5）分离。轴（18）可滑动地容纳在所述柱塞（17）中。所述轴（18）的一端承载有先导阀构件（19）。弹簧（20）接合在所述柱塞（17）和所述轴（18）处，使得所述轴（18）的自由端突出超过柱塞（17）的端面的预定长度。只要所述线圈（15）断电，所述弹簧（20）将所述先导阀构件（19）与先导阀座（9）分离。一旦所述线圈（15）通电，则柱塞（17）被吸引到芯部，轴（18）相对于所述柱塞（17）移位，并且导阀构件（19）从下端所述柱塞（17）关闭所述先导阀座（9）。由于当时的显影压力差，主阀关闭并保持在关闭状态。

摘要： An expansion valve of the degree-of-supercooling control type can be easily adjusted when assembling the degree-of-supercooling of a high-pressure refrigerant control to be held constant if an exerting force adjusting member (7,7') is used for finely adjusting the exerting force. If either a throttling portion (8,8') or a valve seat (4,4') is formed with said exerting force adjusting member (7,7') a simple and compact design or construction can be achieved.
摘要翻译：如果使用施加力调节构件（7,7'）将组合过程中的高压制冷剂控制的过冷却度保持不变，则可以容易地调节过冷度控制型膨胀阀精细调整施加力。如果用所述施加力调节构件（7,7'）形成节流部分（8,8'）或阀座（4,4'），则可以实现简单紧凑的设计或结构。
