Abstract

Opposed vacuum rams effect locking and release respectively, being connected to a vacuum source by a coil driven three way valve. The coil is energized when a key operated cylindr lock effects electrical contact. A common con-rod transmits movement from the rams to the lock, rod to ram connections utilising a pin in a slot to ensure isolated ram function i.e. dispalcement of one ram does not effect pressure in the counter ram. The pins are located by forked plates affixed to the con-rod, manual overide may be by internally accessible draw rods or by radial cylinder lugs engaging a con-rod return.
