Abstract: A fuel oil flow control device has a chamber in which a constant oil level is maintained by a float-controlled inlet valve. If the valve closes at an above normal oil level, the float must be secured in its raised position until manually released by a manually resettable safety device. This device comprises a generally Z-shaped lever comprising an L-shaped operative arm pivoted at its upper end and a lateral counterbalance arm. The lever is disposed adjacent the float and so immersed in the oil that as the oil level exceeds normal, the increased buoyancy of the lever causes it to tilt into locking engagement with the float.

Abstract: In the low speed setting the motor drive pinion drives the cam drum internal gear through a gear train which includes a one-way, spring loaded, ratchet coupling. When the lever is moved to the high speed setting, it removes the spring load holding the clutch output out of engagement with the input so the clutch spring can engage the high speed clutch which results in driving the cam drum at high speed. Since the clutch output and the output of the one-way drive are connected through gearing, the one-way drive overrides its input while the cam drum is driven at high speed. At low speed the clutch output is driven from the cam drum but the clutch is disengaged.

Abstract: The compressor provides hot refrigerant gas to the condenser and flow from the condenser to the evaporator is regulated by the thermostatic expansion valve, the sensing point of which is located in the return line betweeen the evaporator outlet and the wax element actuated suction line valve. A wax element actuated suction line valve is incorporated in the refrigeration system to respond to evaporator outlet temperature and thereby maintain evaporator temperature above a value which would permit frost accumulation on the evaporator. Since the evaporator temperature is controlled, the evaporator pressure is, to some lesser extent, controlled since the two are related. The wax element motor has an inherent temperature lag due to the thermal inertia of the wax and this tends to smooth out or stabilize the system and thus prevent or minimize hunting. The valve remains open as long as the temperature is above the set temperature regardless how low the pressure falls. This, then, enhances fast pulldown of the system. The wax element must be located completely upstream of the valve so as to be unaffected by refrigerant expansion as the valve throttles flow. Thus the wax element is located totally within the temperature to be sensed. In the principal embodiment the valve member is carried directly by the wax element housing and cooperates with the seat which also supports the spider or yoke supporting and guiding the wax element. Another variation incorporates a bellows assembly which functions to seal the wax element from the refrigerant and thus prevent any adverse effect on the elastomers normally incorporated in the wax element motor. In some cases there is no elastomer incorporated in the design with the bellows functioning to contain the wax medium while permitting flexure and, hence, operation of the valve.

Abstract: The dishwasher drain valve provides straight through flow with the valve seat at about 45* to the flow to provide increased velocity tending to straighten the flow of elongated objects (toothpicks, etc.) and decrease chances of such debris becoming lodged in the valve housing. A bellows seals the stem and solenoid from contact with liquids and entrained contaminants. The end of the bellows functions as the valve. Collapse of the bellows onto the stem is prevented by stiffening rings. The stem is guided for linear movement and tolerates some degree of misalignment with the solenoid.

Abstract: Each of the valves shown has parallel flow paths through the body with an expansion valve in the line leading to the evaporator thermostatically controlled by conditions in the return line. A second valve is positioned in the return line and controlled in response to a condition (temperature or pressure) which is indicative of conditions (temperature and pressure) in the evaporator. This arrangement prevents evaporator freezing. The valves are suited for flange fitting by reason of having all ports parallel enabling the valve to be secured to the evaporator (on one side) and to the compressor suction line and the condenser outlet on the other side. Since the thermostatic expansion valve can be ''''externally equalized'''' internally and all control functions are incorporated in the single body, the number of connections to be made by the system assembler are minimized. One version is provided with a receiver-drier which can be changed without disturbing other system connections.

Abstract: The pressure switch has a switch mounted in the plastic, electrically insulative case above the diaphragm. The perimeter of the diaphragm is captured between the plastic case and the cup which has a tubular connector for connection to a source of pressure to be sensed. The chamber below the diaphragm between the diaphragm and cup is the pressure chamber and pressure variations cause flexure of the diaphragm and operation of the switch. The rim of the cup is rolled over the case flange to hold the parts assembled. The mounting bracket is secured to the case and to the appliance (or other equipment) frame - which is electrical ground - and, therefore, satisfies more stringent electrical requirements. In order to ground the cup - even though it is electrically dead - one end of a conductive ground strap is captured between the case and the cup when the cup rim is rolled over the case flange. The other end overlies the bracket and is captured by a screw mounting the bracket to the case. The arrangement meets demanding electrical requirements at very low cost and without requiring added costy manufacturing operation.

Abstract: The continuously driven drive disc carries a drive pawl and a retracting lever on the same pivot. The pawl is biased against the lever by a compressed spring. The lever is held in retractive position by a tension spring. The lever includes a cam which engages a tab (projecting from the timer end plate) to move the lever to an inactive position against the bias of the tension spring while the drive pawl is restrained from following by reason of engagement of a depending finger with a second tab. Continued rotation of the disc clears the finger from the second tab allowing the compressed spring to drive the pawl into engagement with the internal teeth on the timer cam drum thus driving the drum until the lever clears its tab and is retracted by the second (tension) spring. As the lever is retracted it picks up the pawl and retracts the pawl and the drive step is completed. The drive is more economical than the usual stored energy step drive but is more expensive than a creep-type drive. It makes possible variations in steps (degrees and frequency) and even continuous (rapid) drive.

Abstract: The thermostatic expansion valve is provided with an internal by-pass capable of providing rapid equalization of the pressure between the condenser and evaporator when the compressor shuts down. The valve controlling the refrigerant flow has an internal cavity in communication with the condenser pressure and a by-pass port in communication with the evaporator. The valve, urged towards the closed position by a spring, is actuated by the diaphragm through push pins. The push pins normally close the bypass port, either by the lower end of one or more of the push pins cooperating with a seat located at the by-pass port outlet or a valve means (e.g. a flanged collar which guides the valve) interposed the push pins and the by-pass port. With the valve in the closed position, the push pin(s) or valve means can be lifted off the by-pass port by condenser pressure in the cavity, as forces across the diaphragm equalize after shutdown of the compressor. The system pressure is then rapidly equalized through the by-pass port.

Abstract: The sensing rings mounted in the dryer drum are bridged by the tumbling clothes. The voltage is impressed on one of the rings and leaks to ground through the other ring allowing the bias on the grid of the triode to change until the triode passes enough voltage to actuate the relay. The resistance bridging the rings is integrated by reason of the capacitor in the circuit. The triode and relay operate as an electronic switch controlling energization of a power relay to shut off the dryer on receipt of the dry signal or to start a timer to provide an additional time delay period. In another version, the time to reach 20 percent moisture level is measured and the 20 percent moisture signal actuates the timer to continue running for a predetermined proportion of the measured period before shutting off the dryer.
