LAMINATED GLASS AND WINDSHIELD REPAIR DEVICE

摘要

A device is needed that is usable for repairing both bulls-eye cracks and elongate cracks in a laminated glass plate, e.g. a vehicle windshield. For a bulls-eye crack, the device should be capable of drawing air from the crack to be replaced with liquid filler. For an elongate crack, the device should be moveable along the length of the crack while consistently dispensing liquid filler. The present device provides a piston-cylinder combination for both withdrawing air and dispensing liquid filler and including control features that convert between linear actuation of the piston in the cylinder and screw-type actuation of the piston in the cylinder.
