    Abstract: The interior of the bellows is sealed at atmospheric pressure so the pressure on the outside of the bellows is resisted by the atmospheric pressure within the bellows as well as by the spring. When the pressure on the outside of the bellows (which is evaporator pressure in a refrigeration system) exceeds a predetermined amount, the bellows tends to collapse and the head of the bellows pulls away from the actuating pin and allows the spring acting on the pilot valve to open the pilot valve whereupon the pressure to the right of the head of the piston is reduced, allowing the piston to move to the right against the return spring force and thus open the outlet by moving the end of the piston wall past the slot in the stationary sleeve. When the pressure falls below the desired amount, the bellows expands and moves the head of the bellows against the actuating pin to close the pilot valve. Flow through the bleed hole in the end of the piston to the pilot valve chamber rapidly raises the pressure therein so that the return spring can move the piston to close the outlet. Even with the outlet closed, the small port in the piston sleeve allows enough refrigerant flow to insure adequate flow to the compressor to keep the compressor lubricated. The bleed hole in the piston head is sized to require substantial opening of the pilot valve which, therefore, minimizes false opening of the main valve. Controlled leakage to the groove at the pilot end of the piston blocks flow from the pilot valve chamber to the main outlet and stabilizes valve operation.

    Abstract translation: 波纹管的内部在大气压力下被密封，因此波纹管外部的压力受波纹管内的大气压力以及弹簧的抵抗。 当波纹管外部的压力（其是制冷系统中的蒸发器压力）超过预定量时，波纹管倾向于塌缩并且波纹管的头部从致动销拉开并允许弹簧作用在先导阀 以打开先导阀，因此活塞头部右侧的压力减小，允许活塞抵抗复位弹簧力向右移动，从而通过将活塞壁的端部移动通过狭槽而打开出口 固定套筒。 当压力低于所需量时，波纹管膨胀并将波纹管的头部靠在致动销上以关闭先导阀。 流过活塞末端的排放孔到先导阀室，迅速升高其中的压力，使得复位弹簧可以移动活塞以关闭出口。 即使出口关闭，活塞套筒中的小口允许足够的制冷剂流量来确保足够的流量到压缩机以保持压缩机润滑。 活塞头中的排放孔的尺寸设置成要求导阀的大量打开，因此导致主阀的假开口最小化。 在活塞块的先导端处对槽的受控泄漏从先导阀室流到主出口并稳定阀的操作。

    Abstract: The timer has switches including upper and lower passive blades and an active blade therebetween. The distal end of the lower passive blade has depending spacers which straddle the cam upon which the follower on the distal end of the active blade rides. The spacers reference the lower passive blade off the hub of the drum type program cam. The lower passive blade is provided with a rest or stop for the upper passive blade limiting downward movement of that blade. With precision molding, both passive blades are accurately referenced from the cam hub and the location of the follower which actuates the active blade is precisely located. Accuracy of switching is increased without increased precision in manufacture. Use of two cam tracks permits simultaneous actuation of the active and ''''passive'''' blades to effect faster switching. It is possible to provide a ''''makemake'''' arrangement instead of the double throw arrangement.

    Abstract: The switch is designed to be used in a washing machine to sense an out-of-balance condition of the tub during the spin cycle. The assembly is wired into the washer with the coil in series with the washer motor but the coil is normally shunted by a switch which is self biased to its ''''closed'''' position bridging the coil terminals. In this condition the motor operation is normal. When an out-of-balance tub in a clothes washer bumps the wand projecting from the armature the armature is moved to the core of the coil and actuates the switch plunger to open the switch, thus placing the coil in series with the motor. The relatively high impedance of the coil relative to the motor impedance limits motor current so the motor stops. The A-C supply to the coil causes the armature to vibrate (buzz) giving an audible signal that the washer has stopped due to an unbalanced load. The washer is restored to normal by opening the line switch which deenergizes the coil to thereby release the armature and permit the switch to reclose and restore the coil shunt.

    Abstract translation: 该开关设计用于洗衣机，以便在旋转循环期间感测浴缸的不平衡状态。 组件连接到垫圈中，线圈与洗衣机电机串联，但是线圈通常被开关自动分流，该开关自动偏置到桥接线圈端子的“闭合”位置。 在这种情况下，电机运行正常。 当洗衣机中的不平衡桶撞击从电枢突出的魔杖时，衔铁被移动到线圈的芯部并且致动开关柱塞以打开开关，从而将线圈与电动机串联。 线圈相对于电机阻抗的相对较高的阻抗限制电机电流，因此电机停止。 线圈的A-C电源使电枢振动（蜂鸣声），给出一个可听见的信号，表示垫圈由于负载不平衡而停止。 通过打开线圈开关使垫圈恢复正常，线路开关使线圈断电，从而释放电枢，并允许开关重新闭合并恢复线圈分流。

    Abstract: The tubular metering stem is closely guided in the sleeve pressed into the bushing. The upper end of the guide sleeve serves as the valve seat. The stem is provided with a groove which receives the washer as it is coined in a fixture to flow the washer metal into the groove. The spacing between the washer and the corner of the groove below the washer is inadequate to receive the O-ring in a normal manner. Therefore, the corner bites into the O-ring forcing the O-ring against the washer and the bottom of the groove to insure against leakage between the ring and the stem or the washer. The spacing between the O-ring and the valve seat controls the low flow rate as the stem rises. Above low flow the rate is determined by the stem rise and the characteristics of the metering slot. Full shutoff is insured when the O-ring seats on the valve seat.

    Abstract translation: 管状计量杆在被压入衬套中的套筒中被紧密地引导。 导向套筒的上端用作阀座。 杆设置有凹槽，当凹槽被固定在夹具中时，该凹槽接收垫圈以将垫圈金属流入槽中。 垫圈与垫圈下方的槽角之间的间距不足以以正常的方式接收O形圈。 因此，拐角咬入O形环，迫使O形环抵靠垫圈和槽的底部，以确保环与杆或垫圈之间的泄漏。 O形圈和阀座之间的间距控制了阀杆上升时的低流量。 在低流量下，速率由阀杆上升和计量槽的特性决定。 当O形圈座在阀座上时，全开关保险。

    Abstract: Oil flow is regulated by the main float operating the inlet valve to maintain a constant level in the float chamber. Flow from the float chamber is metered by a selected metering orifice in the rotatable disc actuated by the knob. A detent arrangement assures registry of the proper orifice. The small safety float is mounted on the same pivot as the main float and normally moves with the main float but if the inlet valve should leak, causing the oil level in the float chamber to continue to rise to an abnormally high level, the safety float will rise until the ferrous part of the float support bracket comes into the field of the permanent magnet carried by the cover. At this time the float will be lifted with a snap action and the tab standing up from the safety float bracket will strike the arm standing up from the main float bracket. This will deliver a blow to the inlet valve and will maintain the added force on the inlet valve. The control cannot subsequently be placed into operation without first manually depressing the reset button to push the safety float away from the permanent magnet.

    Abstract: The pilot-operated diaphragm valve is controlled by a solenoidactuated plunger guided in a plastic tube having a very thin wall to minimize the loss of magnetic coupling while providing freedom from corrosion and electrolysis with reduced wear and substantial reduction or elimination of vibration buzz or hum. The plastic guide is supported throughout its thin wall length by upper and lower flux sleeves of magnetic material separated by a nonmagnetic material which in this case is a portion of the plastic coil bobbin but can alternatively be any nonmagnetic material. The extended lip on the plastic tube helps seal the diaphragm and prevents extrusion of the diaphragm under high pressure. The flat valve face seating on the rigid valve seat insert in the diaphragm alleviates centering problems and allows increased clearance between the plunger and tube.
