A stator coil assembly is provided comprising: a stator having a stator core;

Hermetically sealed stator coil

An injector is provided, comprising an injector body comprising an inlet passage configured to receive fluid, at least one injection outlet configured to deliver fluid, and a central bore, a needle valve disposed for reciprocal movement within the central bore between a closed position and an opened position; and an actuator configured to move the needle valve between the closed position wherein a first portion of a surface of the valve tip engages a first portion of a surface of the injector body to form a first seal that inhibits flow through the at least one injection outlet, and the opened position wherein a second portion of the surface of the valve tip engages a second portion of the surface of the injector body to form a second seal that inhibits flow through the drain outlet.

Injector method of switching between injection state and drain state

An injector includes a needle and a body. The needle is configured to receive fluid from a fluid supply and operable between a first position, in which the fluid is not provided to a target, and a second position, in which the fluid is provided to the target. The needle includes a first needle bore, a second needle bore, and a first connector. The first needle bore is configured to receive fluid from the fluid supply. The second needle bore is aligned with the first needle bore and configured to provide fluid to the fluid supply. The first connector is in fluid communication with the second needle bore. The body includes an end, a first body bore, and a second body bore. The first body bore is configured to receive the needle. The second body bore is positioned to be contiguous with the end.

Injector including swirl device

Systems and methods including spacers comprising a first face configured to engage with a cam shaft, a second face, and a third face operationally coupled to the first face and the second face, wherein the third face is configured to displace a lubricating fluid and permit rotation of the cam shaft are disclosed.

Systems and methods for reducing the oil volume and windage in fuel pumps

The present disclosure provides a fuel injector for an internal combustion engine with a fuel injector body having a valve chamber, a first conduit in fluid communication with the valve chamber for a first flow of fuel having a first pressure, and a second conduit in fluid communication with the valve chamber for a second flow of fuel having a second pressure. The fuel injector further includes a valve member configured to move between the first conduit and the second conduit. Additionally, an actuator of the fuel injector is configured to move the valve member during a fuel injection cycle. The fuel injector is configured to operate in at least three modes.
