Abstract
The present disclosure relates to a modular fuel injector (100). In particular, the disclosure relates to a “top in bottom out” fuel injector (100) comprising a housing (102) having a fluid inlet (202) at a first, upstream, longitudinal end of the housing (102) and a fluid outlet (108) at a second, downstream, longitudinal end of the housing (102). The injector (100) comprises a plunger (222), and in an open configuration, permits fluid flow from the fluid inlet (202) to the fluid outlet (108) along a flow path comprising a flow path section extending along a longitudinal axis of the housing (102). A fuel injection system is also disclosed. (FIG. 1)

1-31. (canceled)
A fuel injector, comprising:
- a housing comprising:
- a fluid inlet at a first, upstream, longitudinal end of the housing;
- a fluid outlet at a second, downstream, longitudinal end of the housing;
- a valve opening disposed between the fluid inlet and the fluid outlet;
- and a valve seat surrounding the valve opening;
- a ball valve element disposed within the housing;
- a resilient element arranged to bias the ball valve element towards the valve seat to close the valve opening;
- and
- a plunger configured to displace the ball valve element,
- wherein the fuel injector is configurable between a closed configuration, in which the ball valve element is held in the valve seat by the resilient element, and an open configuration, in which the plunger displaces the ball valve element away from the valve seat to permit fluid flow from the fluid inlet to the fluid outlet along a flow path comprising a flow path section extending along a longitudinal axis of the housing.
