Abstract
A first cylinder of a smaller diameter and a second cylinder of a larger diameter are connected in a coaxially intercommunicating state. A first piston of a smaller diameter which is hermetically slidable within the first cylinder is mounted on a rod which is commonly passed through the two cylinders in such a way as to permit the first piston to move also in the second cylinder. Received in the second cylinder is a second piston which is hermetically slidable only in the second cylinder and which is adapted to be integrally coupled with the first piston during movements within the second cylinder.
