| 摘要 | PURPOSE: To prevent an automatic closing again for a long time after removing an overload initially, by preventing a bimetallic snap disc from automatically returning to a normal operating position at the time of cooling. CONSTITUTION: A bimetallic snap disc 7 is prevented from automatically returning to a normal operating position (shape I) at the time of cooling. When the temperature of the bimetallic snap disc 7 rises, the disc 7 rapidly changes the condition of its shape I to a second stable condition of a shape II. At the time of cooling, the bimetallic snap disc maintains this shape II. The bimetallic snap disc can be returned to the shape I only by means of an external force, that is, a mechanical resetting. Due to such a construction, after an overload is removed initially, the bimetallic snap disc is not automatically closed again for a long time. COPYRIGHT: (C)1991,JPO |
