DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(8) With reference now to the drawings, and particularly to FIG. 4, there is shown a cross sectional view of an animal watering valve 1. With reference to FIGS. 1-3 and 5-7, the animal watering valve 1 preferably includes a valve body 10, a valve stem 12, a retention plug 14, a stem o-ring 16 and a compression spring 18. The valve body 10 preferably includes a bullet nose 20 formed on one end and a threaded shank 22 formed on an opposing end thereof. The threaded shank 22 preferably has a diameter, which is less than that of the valve body 10. An o-ring groove 24 is formed between an end of the valve body 20 and an end of the threaded shank 22 to receive a body o-ring. A valve bore 28 is formed in the one end of the valve body 10 to receive the valve stem 12. A through hole 30 is formed through a length of the valve body 10. A plug bore 32 is formed in the opposing end of the valve body to substantially a middle of a length thereof. A portion of an entrance of the plug bore 32 is threaded to form a plug thread 34. The valve stem 12 preferably includes a sealing base 36, an actuation end 38, a plug end 40 and a spring flange 42. The actuation end 38 extends from one end of the sealing base 36 and the spring flange 42 extends from an opposing end of the sealing base 36. With reference to FIG. 3, the actuation end 38 includes an outer perimeter and an end wall. The valve body 10 completely covers the outer perimeter of the actuation end 38, the end wall of the actuation end 38 is not covered by the valve body 10. The plug end 40 extends from the spring flange 42. An o-ring groove 44 is formed in the sealing base 36 to receive the stem o-ring 16. The retention plug 14 preferably includes a threaded portion 46, a rotation flange 48 and a stem portion 50. The stem portion 50 extends from one end of the threaded portion 46 and the rotation flange 48 is formed on an opposing end of the threaded portion 46. A pair opposing flats 52 are preferably formed on an outer perimeter of the rotation flange 48. The plug thread 34 of the valve body 10 is sized to threadably receive the threaded portion 46 of the retention plug 14. A stem bore 54 is formed through the retention plug 14. The stem bore 54 is sized to loosely receive the plug end 40 of the valve stem 12. The compression spring 18 preferably has a conical shape. However, a cylindrical shaped compression spring may also be used.

(9) The animal watering valve 1 is preferably assembled in the following manner. The stem o-ring 16 is inserted into the o-ring groove 44 in the sealing base 36. The plug end 40 of the valve stem 12 is inserted into the compression spring 18, such that a smaller diameter of the conical spring 18 is in contact with the spring flange 42. The actuation end 38 of the valve stem 12 is inserted into plug bore 32, until the stem o-ring 18 contacts a bottom of the plug bore 32. The retention plug 14 is threaded into the plug thread 34 and tightened with a wrench (not shown) applied to the pair of opposing flats 52. With reference to FIG. 4, water is released through a portion of the stem o-ring 18, when the actuation end 38 is pivoted by a tongue of an animal. The valve body 10 is threaded into an animal drinking system (not shown).

(10) While particular embodiments of the invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the invention in its broader aspects, and therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of the invention.
