Abstract (en)
[origin: EP1655477A1] The valve has an actuator sided return (17) that is attached to a control valve sided return (22). The return (17) has a backstroke stop valve (25) for blocking an actuator piston area (8) and is throttled. The actuator piston area interacts with a balancing area in which an elastic compressible balanced body is arranged. The actuator sided return is attached within a valve body containing control valve and a switching valve (3). An independent claim is also included for a fuel injection device.
