ABSTRACT:
An intermittent type swirl injection nozzle providing substantially improved spray characteristics while being easy to manufacture and install. The nozzle includes a nozzle body and a needle valve slidably disposed in a guide hole of the nozzle body with a spray hole communicating a body seat formed inside the nozzle body and the forward end of the needle valve. A swirl passage is provided around the needle valve for giving a swirl flow influence around the axis of the needle valve to fuel when the needle valve is lifted from the body seat. A straight passage is provided in a portion where the inner wall of the guide hole and the needle valve make sliding contact for giving the fuel a straight flow influence in the axial direction of the needle valve. The two flows are joined prior to passing through the spray hole.
