Abstract

An injection system provides an intermittent supply of fuel mixture into combustion spaces of an internal-combustion engine. The system includes a valve and a pipe by way of which a control space in the injection valves may alternatively be acted upon by a pressure. The control space is formed by a valve member and a piston. A first pressure spring presses the valve member onto an injection opening, and a second pressure spring presses the piston away from the injection opening.
