Abstract
A diesel hammer pile driver has a cylinder, a piston displaceably guided in the cylinder and a striker displaceably guided in the cylinder. The striker is disposed underneath the piston in the operating position of the diesel hammer pile driver. A combustion chamber is delimited axially by a face surface of the striker that lies in the interior of the cylinder and by a face surface of the piston, and opens into a fuel feed device connected with a fuel tank disposed on the outside of the cylinder. Using the fuel feed device a predetermined amount of fuel can be introduced into the combustion chamber during each working cycle. The fuel tank is elastically mounted on the cylinder.
