ABSTRACT:
A fuel injector nozzle and tip assembly comprises a check housing having a central axis and defining a cavity therealong with at least one spray orifice at a first end portion of the cavity and a control port of a smaller diameter than the cavity at a second end portion of the cavity. A discharge passage of the housing opens into the cavity at the first end portion. A needle check is disposed in the cavity and has an end portion operably engaging the first end portion of the cavity and operably blocking the orifice in a first position. A control port check is also disposed in the cavity for operable movement between a first position against the second end portion of the cavity blocking fluid flow through the control port and a second position spaced from the second end portion of the cavity permitting fluid flow through the control port. A biasing device is functionally disposed between the needle check and the control port check biasing the control port check and the needle check to their respective first positions.
