摘要： A pressure sensor probe has a first port connectable to a relatively low pressure source in a compressor crankcase and a second port connectable to a relatively high pressure source at the output of an oil pump. A shuttle is slidably disposed in a bore and has a first end which closes the first port when the difference in pressure between the two ports indicative of normal operation exceeds a selected value determined by the relative areas of the shuttle exposed to the respective pressures and by a coil spring which biases the shuttle away from the first port. A passage is formed between the shuttle and the bore leading from the second port to a force receiving surface on the high pressure side of the shuttle. The length and cross sectional area of the passage is selected to provide a desired dampening or time delay between the high pressure source and the force receiving surface. A control circuit includes a reed switch whose state of actuation is dependent upon the position of the shuttle. The control circuit processes the input signal from the reed switch to control the energization of the compressor motor.

摘要： A sealed pressure-responsive switch is manually resettable and trip-free. The switch has a separate snap-acting, bistable, dished metal disc or disc element disposed between a sealed snap-acting pressure-responsive diaphragm and a spring-biased switch arm. The disc moves to an inverted dished configuration with snap action to move the switch arm to a trip position against the arm bias when the diaphragm moves in response to application of a selected fluid pressure. The disc remains in its inverted shape to releasably hold the arm in tripped position until the switch is manually reset even when the diaphragm returns to its original position after removal of the selected fluid pressure from the diaphragm. A push button or push button means is selectively movable to apply a force to the disc sufficient to restore the disc to its original disc configuration after the fluid pressure is removed from the diaphragm, thereby to permit the switch arm to reset in response to its spring bias and provide trip-free manual reset switch operation.
摘要翻译：密封的压力响应开关可手动复位和无跳闸。开关具有设置在密封的快速作用的压力响应膜片和弹簧偏置的开关臂之间的单独的卡扣动作的双稳态碟形金属盘或盘元件。当光阑响应于所选择的流体压力的应用而移动时，盘移动到具有快动作用的倒置碟形配置，以将开关臂移动到克服臂偏压的跳闸位置。盘保持其倒置的形状，以将臂可释放地保持在跳闸位置，直到即使在隔膜从隔膜中移除所选择的流体压力之后膜片返回到其初始位置之后手动复位开关也是如此。按钮或按钮装置可选择性地可移动以在从隔膜移除流体压力之后向盘施加足以将盘恢复到其原始盘配置的力，从而允许开关臂响应于其弹簧而复位偏置并提供无跳闸手动复位开关操作。
