摘要： An electrical switch actuatable upon the occurrence of a preselected level, includes a generally cup shaped, open ended housing which mounts therein a spaced pair of stationary contacts. The housing has two pairs of upwardly extending channels in its side walls, the two channels of the first pair aligned with the stationary contacts and the two channels of the second pair aligned with platform surfaces. An electrically conductive, flexible cruciform element is disposed in the housing with the distal end portions of two legs of the cruciform received respectively in the two channels of the first pair, and the distal end portions of the other two legs of the cruciform received respectively in the two channels of the second pair and resting on the platform surfaces. The stationary contacts may be disposed above or beneath the cruciform element for a normally open or normally closed switch as desired. The stationary contacts may lie in a plane parallel to the plane of the snap acting member or in planes which intersect each other and the plane of the snap acting member. A motion transfer pin extends between the snap acting member and the cruciform element and may be provided with a shoulder to prevent overtravel of the pin.
摘要翻译：在预先设定的水平位置上可启动的电开关包括一个大致为杯形的开放式外壳，其中安装有一对间隔开的固定触点。壳体在其侧壁中具有两对向上延伸的通道，第一对的两个通道与固定触点对准，并且第二对的两个通道与平台表面对准。导电的，柔性的十字形元件设置在壳体中，十字形的两个腿的远端部分别容纳在第一对的两个通道中，十字形的另外两个腿的远端部分别接收在第二对的两个通道并且搁置在平台表面上。根据需要，固定触点可以设置在十字形元件的上方或下方，用于常开或常闭开关。固定触点可以位于平行于卡扣作用构件的平面的平面中，或者位于与快速作用构件相交的平面中。运动传递销在卡扣作用构件和十字形元件之间延伸并且可以设置有肩部以防止销的超程。

摘要： A flow control valve is disclosed in a household refrigeration appliance having a vapor compression refrigeration system comprising a cyclically operated compressor, a condenser, an evaporator and an expansion device between the condenser and the evaporator. The refrigerant flow control valve is disposed between the condenser and the evaporator and comprises a housing defining a refrigerant flow chamber for receiving liquified refrigerant from the condenser outlet, valve seat structure defining a refrigerant flow port for communicating refrigerant from the condenser to the evaporator, and a flow controlling valve assembly coacting with the valve seat structure to control the refrigerant flow from the refrigerant flow chamber to the expansion device. The flow control valve controls system refrigerant flow in response to subcooling, blocks refrigerant flow from the condenser when the compressor is cycled off and enables circulation of hot gaseous refrigerant under extreme high temperature ambient conditions.
摘要翻译：在具有蒸气压缩制冷系统的家用制冷设备中公开了流量控制阀，所述蒸气压缩制冷系统包括循环操作的压缩机，冷凝器，蒸发器和在冷凝器和蒸发器之间的膨胀装置。制冷剂流量控制阀设置在冷凝器和蒸发器之间，并且包括限定用于从冷凝器出口接收液化制冷剂的制冷剂流动室的壳体，限定用于将制冷剂从冷凝器连通到蒸发器的制冷剂流动端口的阀座结构，以及与阀座结构共同作用以控制从制冷剂流动室到膨胀装置的制冷剂流动的流量控制阀组件。流量控制阀响应于过冷而控制系统制冷剂流动，当压缩机循环时阻止来自冷凝器的制冷剂流，并使得在极高温环境条件下能够循环热气态制冷剂。

摘要： A pressure responsive control device having a pressure housing assembly defining a pressure chamber, an actuable control fixed to the housing assembly and, a pressure transducer module hermetically closing the pressure chamber. The module includes a snap acting pressure responsive diaphragm, a diaphragm control plate hermetically bonded to the diaphragm outer periphery, and a support member hermetically joined to and supporting the control plate and hermetically joined to the housing assembly. The control plate has a supporting region rigidly supporting the diaphragm and the diaphragm control regions are yielded and deformed relative to the supporting region to position the control regions for stressing the diaphragm to determine the chamber pressure levels at which the diaphragm moves.
