Coupling |
摘要 |
A coupling between parts subject to differential expansion and contraction comprising first and second sealing abutments and an intervening constraint on relative movement whereby differential movements provide a self-compensating tightening and loosening of the sealing abutments. The coupling is especially useful for joining tubular parts such as caps or spray nozzles in containers for agricultural chemicals.
