Mechanism for opening and closing at least one form in a glass-making machine.

摘要

The mechanism comprises a piston and cylinder assembly operable to move mould side portion supports between mould open and mould closed positions thereof. Check valve means (72, 74, 76, 78, 80, 82) is mounted in a passage (66) into the cylinder to allow fluid under pressure to enter the cylinder through the passage but to prevent exit of fluid through said passage. The check valve means is mounted in a chamber (66f) defined partially by the end cap (60) and partially by a cover member (67) removably mounted on the top of the end cap (60). When the cover member (67) is removed from the end cap (60), the check valve means can be removed.
