Abstract

The body has two blades mounted at the front. One blade is movable and is connected to a drive piston which slides in a bore in the body. A valve is located between the piston and the front part of the body and its movable parts are axially displaceable perpendicularly to the direction of movement of the piston rod. A part of the valve crosses the bore in which the piston slides and passes through a slot in the piston rod. Compressed air is admitted to the piston via a hollow rear part of the piston rod.
