Abstract
A thermally actuated energy regulator of the kind including a switch controlled through a heat responsive actuator in the form of a bi-metal assembly. A lever is arranged to act between the actuator and the switch so as to actuate a switch in response to pressure applied to the lever by deflection of the actuator, which deflection occurs when the heater associated with the actuator is energized. The lever reacts against a fulcrum, the position of which is adjustable through a cam, and that adjustment permits variation of the amount of deflection of the actuator necessary to cause operation of the switch through the interacting lever. The switch, actuator and cam are secured to a body section in fixed relationship so that calibration of the regulator is simplified.
Claims16
An electrical energy regulator including;
- a body section;
- an actuator attached to said body section and having a heater associated therewith, part of said actuator being movable relative to the remainder thereof in response to energization of said heater;
- switch means secured to said body section in predetermined relation to said actuator;
- lever means acting between said actuator and said switch means and being movable about a fulcrum in response to said movement of the actuator and to thereby cause actuation of said switch means;
- and cam means movably mounted on said body section and being operable to adjust the position of said fulcrum relative to said actuator and to thereby alter the amount of movement of said actuator part necessary to cause actuation of said switch means.
An electrical energy regulator including a body section;
- an actuator attached to said body section and having a heater associated therewith, part of said actuator tending to deflect in response to energization of said heater;
- switch means secured to said body section in predetermined relation to said actuator;
- lever means acting between said actuator and said switch means and being responsive to pressure applied thereto by deflection of said actuator part to cause actuation of said switch means;
- said lever means reacting against a fulcrum when said pressure is applied thereto;
- and cam means movably mounted on said body section and being operable to adjust the position of said fulcrum relative to said actuator and to thereby alter the pressure necessary between said actuator and said lever means to cause actuation of said switch means.
An electrical energy regulator including a body section;
- an actuator attached to said body section and having a heater associated therewith, part of said actuator tending to deflect in response to energization of said heater;
- switch means secured to said body section in predetermined relation to said actuator;
- lever means acting between said actuator and said switch means and being responsive to pressure applied thereto by deflection of said actuator part to cause actuation of said switch means;
- said lever means reacting against a fulcrum when said pressure is applied thereto;
- a cam member rotatably mounted on said body section in a fixed position relative to said actuator;
- and a cam follower connected to said fulcrum and engaging a cam surface of said cam member, whereby rotation of said cam member is operative to adjust the position of said fulcrum relative to said actuator and to thereby alter the pressure necessary between said actuator and said lever means to cause actuation of said switch means.
