摘要:
A fuel injector includes a fuel injector body defining a fuel inlet and at least one fuel outlet, a valve having a first valve state and a second valve state and an actuator for the valve. The fuel injector includes a biasing spring including a cylindrical rolled sheet having a first spring end, a second spring end and defining a longitudinal center axis. The cylindrical rolled sheet is configured to change in length to bias the actuator toward the first actuator position and includes a helical seam located between the first spring end and a second spring end which has a shape adapted to reduce non-uniformity in a spring constant via distributing stiffness about the longitudinal center axis.

摘要:
A filter and filter cleaning system wherein the filter is reusable after ultrasonic cleaning in a tank. The filter is disassembled, separating the filter element from the case. The filter element comprises a micromesh metallic filter core that traps contaminants within it during normal use. The micromesh core element is cleaned in a liquid bath while being exposed to ultrasonic vibrations that shake the contaminants from the mesh filter structure. The contaminants are washed from the mesh by the fluid bath as they are separated from the mesh structure. Once cleaned, the filter is reassembled and can be reused unlike typical paper care filters that must be discarded.

A method for vaporizing organic materials onto a substrate surface to form a film including providing a quantity of organic material into a vaporization apparatus and actively maintaining the organic material in a first heating region in the vaporization apparatus to be below the vaporization temperature. The method also includes heating a second heating region of the vaporization apparatus above the vaporization temperature of the organic material and metering, at a controlled rate, organic material from the first heating region into the second heating region so that a thin cross section of the organic material is heated at a desired rate-dependent vaporization temperature, whereby organic material vaporizes and forms a film on the substrate surface.
