Automatic Three-Way Diverter Valve
First Claim
1. A fluid delivery device comprising a three-way diverter valve assembly, the three-way diverter valve assembly comprising:
- (i) a valve housing having a valve body and a valve cap, said valve housing providing a first fluid passageway, a second fluid passageway, and a third fluid passageway, each having an access opening; and
(ii) a resilient valve component within said valve housing;
wherein the resilient valve component is movable from a first position to a second position, said first position providing a fluid pathway between the first fluid passageway and the second fluid passageway, and said second position providing a fluid pathway between the third fluid passageway and the first fluid passageway.

18. A method of loading a fluid delivery apparatus, comprising:
-
(i) using a fluid delivery device comprising; (1) a headpiece including at least one tubular barrel, said tubular barrel including a plunger disposed within an interior of the tubular barrel; (2) an applicator having a lumen in fluid communication with said interior of said tubular barrel; and (3) a three way diverter valve assembly in fluid communication with an interior of said at least one barrel and an interior of lumen of said applicator, said valve assembly comprising; (i) a valve housing having a valve body and a valve cap, said valve housing providing a first fluid passageway, a second fluid passageway, and a third fluid passageway, each having an access opening; and (ii) a resilient valve component within said valve housing having a first end;
a second end;
a flange between said first end and said second end;
wherein the resilient valve component is movable from a first position to a second position;
said first position providing a fluid pathway between the first fluid passageway and the second fluid passageway and allowing flow of fluid from said barrel interior to said applicator lumen interior; and
said second position providing a fluid pathway between the third fluid passageway and the first fluid passageway and allowing flow of fluid from said valve cap to said barrel interior;(ii) securing a loading cup to said valve cap, said loading cup having an open interior and an opening at a bottom portion, wherein said bottom portion urges said resilient valve component into said second position; (iii) placing a fluid material within the interior of said loading cup; and (iv) withdrawing said plunger from said barrel, so as to draw said fluid material into the interior of said barrel. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
