Abstract
A fluid applicator used to apply an even coat of fluid to a surface which is not accessible along a longitudinal axis of the applicator. The applicator includes a fluid delivery system that delivers the fluid under low pressure, and has a distal end bent 30° to 60° from the applicator's longitudinal axis. The applicator also has an air delivery system with a distal end bent at an angle identical to the distal end of the fluid delivery system. The air delivery system delivers a high pressure jet of air 90° relative to the fluid, thereby aspirating the fluid and ejecting it onto the inaccessible surface.
Claims8
An apparatus for coating a fluid onto an unviewable surface comprising:
- a fluid feed system including:
- a pressure pot for pressurizing the fluid;
- a variable fluid control unit for controlling the feed rate of the fluid;
- a fluid line for delivering the fluid, said fluid line being bent between 30° and 60° to allow the fluid to be distributed to the unviewable surface;
- and
- a fluid spray tip for dispensing the fluid under low pressure;
- and
- an air feed system including:
- a compressed air source for pressurizing air;
- an air line for delivering the air, said air line being parallel to said fluid line and bent between 30° and 60° to allow a jet of air to be directed at the unviewable surface;
- and
- an air spray tip positioned 90° relative to said fluid spray tip for providing a high pressure jet of air to contact the low pressure fluid on said fluid spray tip and atomize and eject the fluid onto the unviewable surface in an even manner.
A fluid applicator used to apply an even coat of fluid to a surface which is not accessible along a longitudinal axis of the applicator, the surface being positioned 120° to 150° relative to the longitudinal axis of the applicator, said applicator comprising:
- a fluid delivery system that delivers the fluid under low pressure having a distal end bent 30° to 60° from the longitudinal axis of the applicator;
- and
- an air delivery system having a distal end bent at an angle identical to said distal end of said fluid delivery system, wherein the air delivery system delivers a high pressure jet of air 90° relative to the fluid, thereby aspirating the fluid and ejecting it onto the surface.
