Abstract
Disclosed are example embodiments of a fuel injection device having a plunger that moves at a predetermined reciprocating motion from an initial position, the fuel injection device includes: an electromagnetic coil; a tubular bobbin within the electromagnetic coil, wherein the electromagnetic coil is configured to move the tubular bobbin when energized; a fuel intake channel; and an inlet check valve disposed along a fuel pathway of the fuel intake channel, the inlet check valve configured to allow fuel to flow through and to a pressurization chamber, wherein the inlet check valve is a normally open valve.
Claims16
A fuel injection device with a plunger that moves at a predetermined reciprocating motion from an initial position, the fuel injection device comprising:
- an electromagnetic coil;
- a tubular bobbin within the electromagnetic coil, wherein the electromagnetic coil is configured to move the tubular bobbin when energized;
- a fuel intake channel;
- and
- an inlet check valve disposed along a fuel pathway of the fuel intake channel, the inlet check valve configured to allow fuel to flow through and to a pressurization chamber, wherein the inlet check valve is a normally open valve.
A fuel injector comprising:
- a pressurization chamber;
- a fuel intake channel;
- and
- an inlet check valve having a communication port fluidically coupled to the fuel intake channel and one or more outlets fluidically coupled to the pressurization chamber, wherein the communication port is disposed along a longitudinal axis of the fuel intake chamber such that fuel can flow from the fuel intake channel to the pressurization chamber in a substantially linear direction.
