CONTROLLER FOR OVERHEATING PROTECTION OF VESSEL PURPOSED FOR LIQUID HEATING Russian patent published in 2013 - IPC H01H37/52 H01H37/54 H01H37/72 

FIELD: electricity.

SUBSTANCE: controller contains a control element, monolithic double-acting bimetal actuating mechanism located at the upper surface of control element and two groups of changeover contacts placed at control element; each group of changeover contacts interact with respective actuators. Joint monolithic double-acting bimetal actuating mechanism consists of two joint actuators which are relatively independent and made of bimetal sheet. Edge line of each of two actuators is located partially at inner side of the edge line of another actuator. At that bimetal actuating mechanism has common connecting part, which is located at inner side of edge line of each actuator and forms effectively out of two actuators joint monolithic heat sensitive and bimetal double-acting actuating mechanism.

EFFECT: improving reliability of overheating protection, accuracy and actuating uniformity.
