Piston and cylinder devices
Abstract
Abstract A PISTON AND CYLINDER DEVICE HAS AN ADJUSTABLE STOP ARRANGEMENT FOR LIMITING THE STROKE OF THE PISTON. THIS ADJUSTABLE STOP ARRANGEMENT COMPRISES A CASING AND A PLURALITY OF STOP ELEMENTS LOCATED IN SAID CASING IN ALIGNMENT WITH EACH OTHER AND WITH A PISTON-ROD-LIKE MEMBER ASSOCIATED WITH THE PISTON. THE STOP ELEMENTS ARE REMOVABLE FROM THE CASING AND HAVE TWO POSITIONS THEREIN ONE OF WHICH THEY EMBRACE SAID PISTON-ROD-LIKE MEMBER SO AS NOT TO OBSTRUCT MOVEMENT OF IT AND OF THE PISTON AND IN THE OTHER OF WHICH THEY OBSTRUCT MOVEMENT OF THE PISTONROD-LIKE MEMBER. BY RE-ARRANGING THE STOP ELEMENTS IN THE CASING THE PERMITTED STROKE OF THE PISTON CAN BE INCREASED OR DECREASED AS REQUIRED.
