Abstract
An induction device for electrification of droplets of hydraulic nozzles comprises: an electrode comprising one or more attachment legs; and an induction electrode holder configured to receive the electrode, wherein the one or more attachment legs are fixed within tubular structures of the induction electrode holder, and wherein a finite distance is formed between an outer surface of each attachment leg in the one or more attachment legs and an inner surface of each tube of the tubular structures.
Claims14
An induction device for electrification of droplets of a hydraulic nozzle, the nozzle discharging the droplets in a spray pattern, the induction device comprising:
- an electrode comprising one or more attachment legs and a transverse portion electrically exposed to the discharging droplets of the spray pattern, the transverse portion extending transversely relative to the one or more attachment legs and extending in a plane co-planar with a cross-sectional plane of the spray pattern;
- and
- an induction electrode holder configured to receive the electrode, wherein the one or more attachment legs each have a first leg end that is fixed within corresponding one or more tubular orifices of the induction electrode holder, each tubular orifice being open at a first end with the corresponding attachment leg extending in a longitudinal direction from the first leg end through the open first end with an open space defined by the open first end of the tubular orifice surrounding the respective attachment leg where the attachment leg exits the first end of the tubular orifice, and wherein a finite distance is formed between an outer surface of each attachment leg in the one or more attachment legs and an inner surface of each of the tubular orifices in which the one or more attachment legs are fixed, the finite distance defining a gap between the outer surface of each attachment leg and the inner surface of the corresponding tubular orifice at the open first end of the corresponding tubular orifice;
- wherein the finite distance and the gap are large enough to prevent a formation of continuous liquid film;
- wherein the one or more attachment legs each have a respective terminal second leg end that is spaced further in the longitudinal direction from the first leg end than the open first end of the tubular orifice.

A hydraulic spray nozzle assembly comprising:
- a spray nozzle configured to spray liquid as a thin sheet in a discharge direction in a spray pattern, the thin sheet further breaking into liquid droplets;
- an electrode comprising one or more attachment legs and a transverse portion electrically exposed to the discharging liquid droplets, the transverse portion extending transversely relative to the one or more attachment legs and extending in a plane co-planar with a cross-sectional plane of the spray pattern, the electrode configured to induce charge in the liquid droplets;
- and
- an induction electrode holder comprising one or more tubular orifices, the induction electrode holder configured to receive the electrode, wherein the one or more attachment legs each have a first leg end that is fixed within the one or more tubular orifices, each tubular orifice being open at a first end with the corresponding attachment leg extending in a longitudinal direction from the first leg end through the open first end with an open space defined by the open first end of the orifice surrounding the respective attachment leg where the attachment leg exits the first end of the tubular orifice, and wherein a finite distance is formed between an outer surface of each attachment leg in the one or more attachment legs and an inner surface of each of the one or more tubular orifices in which a corresponding attachment leg is received, the finite distance defining a gap between the outer surface of each attachment leg and the inner surface of the corresponding tubular orifice at the open first end of the corresponding tubular orifice;
- wherein the finite distance and the gap are large enough to prevent a formation of continuous liquid film on the electrode, the induction electrode holder, or the spray nozzle;
- wherein the one or more attachment legs each have a respective terminal second leg end that is spaced further in the longitudinal direction from the first leg end than the open first end of the tubular orifice.
