PISTON ROD AND CYLINDER SEAL DEVICE FOR ALUMINUM BATH CRUST BREAKER |
摘要 |
A piston rod and cylinder seal device includes a cylinder defining a piston chamber extending between first and second cylinder heads. The second cylinder head has a spud receiving bore, a pressure passage communicating with the spud receiving bore, and a bore supply/vent passage. A first piston is disposed in the piston chamber. A piston rod is connected to the piston, the piston rod having a piston rod spud extending beyond the first piston and including a blind shaft receiving bore. A second piston slidably disposed in the blind shaft receiving bore has a seal member connected thereto. A contact member connected to the second cylinder head in the spud receiving bore has a central passage extending therethrough in communication with the bore supply/vent passage. The seal member when contacting the contact member acts to seal the central passage. |
