摘要： A refrigeration apparatus containing a thermostat, adapted for use in a food storage compartment potentially containing a flammable gas, includes a thermostat and an enclosure forming a chamber configured to house the thermostat. The enclosure has two umbrella-type check valves configured to permit gas to pass into the chamber or out of the chamber when a predetermined pressure differential exists between the chamber and the food storage compartment. The enclosure forms a seal with the thermostat so that gas only passes through the check valves.

摘要： A temperature responsive switch includes a housing, electrical contacts, an actuator arm, a rotatable shaft, and a cam assembly to open and close an electrical power circuit in response to environmental conditions. The cam assembly includes a cam and a cam follower attached to the actuator arm with a bias spring and contacting a cam surface. The cam surface has a first portion for adjusting the temperature calibration of the switch, and a second portion for positioning the cam follower in an OFF position that reduces the load on the bias spring. Thus, spring losses are avoided when the cam follower is in the OFF position, and the switch may be more accurately calibrated and adjusted when the switch is returned from the OFF position.

摘要： A method of making a control device having an opening therein, at least a pair of abutments on the control device within the opening and having a pair of laterally spaced apart points thereon defining a chord of the opening, and a snap-action member in the opening and operable between a stable configuration and an unstable configuration thereof with the snap action member being engaged only in the unstable configuration thereof the at least abutment means pair. In this method, the snap-action member is formed into the stable configuration thereof from a metallic material having a directed grain structure. The snap-action member is seated on the control device in a preselected assembly position so as to extend at least in part about the opening, and the direction of the grain orientation of the snap-action member is aligned so as to extend generally perpendicularly with respect to the chord of the opening.

摘要： A condition-responsive electric switch mechanism for use in controlling a compressor of a refrigeration appliance. The switch mechanism includes first, second and third terminals, an actuator movable as a function of a detected condition and a bistable spring switch element electrically connected to the first terminal. The spring switch element includes a movable contact and is adapted for snap-acting movement between an open and a closed position. In the open position, the movable contact of the spring switch element is spaced apart from a fixed contact mounted on the second terminal. In the closed position, the movable contact engages the fixed contact to electrically connect the first and second terminals. The spring switch element also includes a toggle blade operable by engagement with the actuator for motion through a first switch point. At the first switch point, the spring switch element snaps between the open and closed positions. The toggle blade is operable by further engagement with the actuator for motion past the first switch point to a second switch point. At the second switch point, the toggle blade electrical connects the first and third terminals to enable an alarm.

摘要： An assembly for use in a condition responsive mechanism. The assembly includes a housing part having aperture means therethrough and a control device rotatably assembled at least in part in the aperture means for selecting a set temperature of the condition responsive mechanism. The housing part has a pair of sections extending generally about at least a part of the aperture means and predeterminately spaced in off-set relation with respect to each other. The control device has a body portion formed of a generally resilient resin material and includes groove means extending thereabout for receiving in rotatable abutment the off-set sections. The groove means defines with the body portion at least one flange thereon with the flange being displaced in response to the rotatable abutment of the groove means and off-set sections so as to resile and exert a force acting to maintain the rotatable abutment between the groove means and the off-set sections.A method of assembly is also disclosed.
