Choke pin nozzle |
摘要 |
A choke pin nozzle for diesel engines in which the choke pin is arranged on a nozzle needle. The nozzle needle is axially guided in a fitted bore in a nozzle body and is braced, through a separate spring plate, on a helicoidal compression spring disposed in a spring chamber or cavity of the nozzle. The spring plate is formed as a component of an intermediate piston which is connected on the nozzle side and guided axially with a seal in a portion of the nozzle. An escape or discharge bore is provided in the intermediate nozzle with the bore opening into the spring cavity. The piston is of a smaller diameter than the nozzle needle. The intermediate piston includes a bearing face which is cooperable with an upper sealing surface of the nozzle needle. A guide bore of the intermediate piston is widened in a stroke zone of the bearing face at least to a diameter of the fitted bore in which the nozzle needle is axially guided.
