Abstract (en)
[origin: US4572434A] A fuel injection nozzle for internal combustion engines having a valve needle opening outward and connected with a piston which defines a damping chamber filled with fuel. Upon the opening stroke of the valve needle, the damping chamber communicates with the flow path of the fuel only via a throttling conduit. The damping chamber is formed in a cap, which is mounted upon the piston and centers itself on the piston. The cap is supported on the nozzle housing toward the side of the injection opening via a pre-stressed support spring, and the cap and the support spring are confined between stops attached to the housing. Therefore, the damping can be limited in a manner dependent on pressure or speed.
