Title:
【発明の名称】内燃機関用燃料噴射ノズル
Document Type and Number:
Japanese Patent JPS60500268
Kind Code:
A
Abstract:
Fuel nozzle for internal combustion engines, with a valve needle (26) opening outwardly, connected to a piston (46) delimiting a vaporization chamber (60) filled with fuel and connected upon the first partial rise of the valve needle (26) to the fuel flow path only by a throttle connection. The vaporization chamber (60) is formed within a cap (48) arranged on the piston (46) and centered thereto. The throttle connection is comprised of at least one throttle channel (66, 68, 69, 72) of which the passage cross-section, contrary to embodiments of the main patent application, is modified as a function of the rise of the valve needle (26). The original cross-section of the throttle connection may thereby be limited to a very small value, without the throttling having negative effects upon the increase of the rotation speed and rises of the needle. In certain applications, the original throttling cross-section may be conveniently determined by a fixedly regulated shutter (62).
