Abstract
An ink jet droplet generator body for an ink jet droplet generator comprising an orifice plate with a plurality of nozzles forming a jet array entails a throughbore with an entrance and exit port, the throughbore provides a path through that flows fluid from a fluid supply to the first slot. The first slot connects the throughbore to the orifice plate. One or more holes or a slot are located in the top of the generator body to direct fluid or a secondary source of fluid to the first slot and then the orifice plate.

An ink jet droplet generator body (8) for an ink jet droplet generator (5) comprising an orifice plate (6) with a plurality of nozzles (9a, 9b, and 9c) forming a jet array (10), wherein the generator body (8)comprises:
- a. a throughbore (13) comprising a first port and a second port, wherein the throughbore (13) is adapted to flow a fluid (16) from a fluid supply (17) to the orifice plate (6);
- b. a first slot (18) disposed in the generator body (8) in communication with the throughbore (13), wherein the first slot (18) is adapted to flow the fluid (16) from the throughbore (13) to the orifice plate (6);
- c. at least one discrete hole (20a, 20b, and 20c) disposed in the generator body (8) opposite the first slot (18), wherein the at least one discrete holes (20a, 20b, and 20c) is adapted to receive additional fluid from the fluid supply (17) and communicate the additional fluid to the throughbore (13);
- and
- d. a seal (25) disposed between the first slot (18) and the fluid supply (17).
An ink jet droplet generator body for an ink jet droplet generator comprising an orifice plate with a plurality of nozzles forming a jet array, wherein the generator body comprises:
- a. a throughbore comprising a first port and a second port, wherein the throughbore is adapted to flow a fluid from a fluid supply to the orifice plate;
- b. a first slot disposed in the generator body in communication with to the throughbore, wherein the first slot is adapted to flow the fluid from the throughbore to the orifice plate;
- c. a second slot disposed in the generator body opposite the first slot, wherein the second slot is adapted to receive additional fluid from the fluid supply and communicate the additional fluid to the throughbore;
- and
- d. a seal disposed between the second slot and the fluid supply.
An ink jet droplet generator body for an ink jet droplet generator comprising an orifice plate with a plurality of nozzles forming a jet array, wherein the generator body comprises:
- a. a first slot disposed in the generator body vertically above the orifice plate;
- b. a second slot disposed in the generator body vertically above the first slot, wherein the second slot is in communication with the first slot and a fluid supply, and wherein a fluid flows from the second slot to the first slot and thence vertically below to the orifice plate;
- and
- c. a seal disposed between the second slot and the fluid supply.
An ink jet droplet generator body for an ink jet droplet generator comprising an orifice plate with a plurality of nozzles forming a jet array, wherein the generator body comprises:
- a. a first slot disposed in the generator body;
- b. a second slot disposed in the generator body opposite the first slot, wherein the second slot is in communication with the first slot and a fluid supply, and wherein a fluid flows from the second slot to the first slot;
- and
- c. a seal disposed between the second slot and the fluid supply, and
- wherein the second slot has a first end wall and a second end wall opposite one another and the end walls are sloped to converge toward the orifice plate.
