| 发明名称 | Sealing member with visible pressure and temperature indication | ||
| 摘要 | A sealing member for a machine may include an elastomeric body configured to fit at least partially into a recess defined in at least one of two sealing surfaces of two mating parts of the machine. The elastomeric body may include a visible indicator portion extending out from between the two mating parts. The elastomeric body may further include an elastomeric compound, and at least one of a thermochromic dye and a piezochromic dye mixed into the elastomeric compound, wherein the thermochromic dye is adapted to change color upon exposure of the elastomeric body to a temperature above a threshold temperature, and the piezochromic dye is adapted to change color upon exposure of the elastomeric body to a pressure above a threshold pressure. | ||

| 主权项 | 1. A sealing member for a machine, comprising: an elastomeric body configured to fit at least partially into a recess defined in at least one of two sealing surfaces of two mating parts of the machine, the elastomeric body including: a visible indicator portion extending out from between the two mating parts;an elastomeric compound;a thermochromic dye; anda piezochromic dye,wherein the thermochromic dye is adapted to change color upon exposure of the elastomeric body to a temperature above a threshold temperature, and the piezochromic dye is adapted to change color upon exposure of the elastomeric body to a pressure above a threshold pressure. | ||
