<p>The pressure amplification device (10) has an inner piston (38) and an outer piston (25) arranged concentric to each other. The pistons are arranged in a housing. The inner piston is arranged in an axially displaceable manner in the outer piston. A control chamber (31) is formed by the outer piston and the housing. The control chamber is connected with a fuel return line in a switching position of a control valve (20). Another control chamber (44) is formed between the inner piston and the outer piston, which is connected with the fuel return line in the switching position.</p> |
