Abstract
Abstract A valve assembly includes: A. A VALVE BODY HAVING A SIDE INLET AND A BOTTOM OUTLET, THERE BEING A DOWNWARDLY FACING ANNULAR SEAT IN THE BODY THROUGH WHICH FLUID PASSES IN FLOWING TO THE OUTLET, B. A STOPPER UPWARDLY ENGAGABLE AGAINST THE SEAT AND A STEM CARRYING THE STOPPER AND PROJECTING UPWARDLY IN THE BODY, C. YIELDABLE MEANS URGING THE STEM UPWARDLY, AND D. A DEVICE SEALING OFF OVER THE BODY PROXIMATE THE STEM UPPER TERMINAL AND HAVING A FLEXIBLE UPPER PORTION EXPOSED UPWARDLY AND PROJECTING OVER THE STEM UPPER TERMINAL, WHEREBY SAID TERMINAL MAY BE DEPRESSED THROUGH SAID DEVICE TO URGE THE STEM AND STOPPER DOWNWARDLY FOR OPENING THE VALVE.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
197 words
In a valve assembly, a. a valve body having a side inlet and a bottom outlet, there being a downwardly facing annular seat in the body through which fluid passes in flowing to the outlet, b. a stopper upwardly engageable against the seat and a stem carrying the stopper and projecting upwardly in the body, there being top flange structure on the stem, c. a coil spring urging the stem upwardly, said spring in its entirety extending about the stem above the level of the side inlet and directly below the top flange structure, d. a device sealing off over the body proximate the stem upper terminal and having a flexible upper portion exposed upwardly and projecting over the stem upper terminal, whereby said terminal may be depressed through said device to urge the stem and stopper downwardly for opening the valve, and e. there being an annular retainer on the body and retaining said device thereto, said device having the form of a cap projecting upwardly through the retainer and about the upper extent of the spring in order to project over the top flange structure on the stem for presentation as a downwardly depressible pushbutton.
Claim 2
Dependent Claim
197 words
In a valve assembly, a. a valve body having a side inlet and a bottom outlet, there being a downwardly facing annular seat in the body through which fluid passes in flowing to the outlet, b. a stopper upwardly engageable against the seat and a stem carrying the stopper and projecting upwardly in the body, there being top flange structure on the stem, c. a coil spring urging the stem upwardly, said spring in its entirety extending about the stem above the level of the side inlet and directly below the top flange structure, d. a device sealing off over the body proximate the stem upper terminal and having a flexible upper portion exposed upwardly and projecting over the stem upper terminal, whereby said terminal may be depressed through said device to urge the stem and stopper downwardly for opening the valve, and e. there being an annular retainer on the body and retaining said device thereto, said device having the form of a cap projecting upwardly through the retainer and about the upper extent of the spring in order to project over the top flange structure on the stem for presentation as a downwardly depressible pushbutton.
Claim 3
Dependent Claim
25 words
The valve assembly of claim 1 wherein said cap consists of a flexible plastic material and said valve body consists of rigid molded plastic material.
Claim 4
Dependent Claim
25 words
The valve assembly of claim 2 wherein said stem and body forM clearance through which fluid pressure may leak to the underside of the cap.
Claim 5
Dependent Claim
68 words
The valve assembly of claim 1 wherein said body forms a flow chamber between said stopper and outlet, there being guides projecting generally inwardly and downwardly in the chamber and from between which fluid drains in a vertical non-splashing discharge stream issuing from the outlet, said guides having vertically elongated inward terminals which extend closely about the stopper to center the stopper during its downward and upward movement.
Claim 6
Dependent Claim
19 words
The valve assembly of claim 4 wherein said guides project inwardly from the interior wall of the flow chamber.
Claim 7
Dependent Claim
30 words
The valve assembly of claim 1 including a sideward projection on the body to receive upward manual finger pressure when thumb pressure is exerted downwardly on said device upper portion.
Claim 8
Dependent Claim
21 words
The valve assembly of claim 1 including a water cooler receptacle supporting said body in water delivering relation with said inlet.
Claim 9
Dependent Claim
189 words
In a valve assembly, a. a valve body having a side inlet and a bottom outlet, there being a downwardly facing annular seat in the body through which fluid passes in flowing to the outlet, b. a stopper upwardly engageable against the seat and a stem carrying the stopper and projecting upwardly in the body, c. yieldable means urging the stem upwardly, d. a device sealing off over the body proximate the stem upper terminal and having a flexible upper portion exposed upwardly and projecting over the stem upper terminal, whereby said terminal may be depressed through said device to urge the stem and stopper downwardly for opening the valve, e. an annular retainer on the body and retaining said device thereto, said device having the form of a cap projecting upwardly through the retainer in order to project over the upper terminal of the stem for presentation as a downwardly depressible push button,and f. the stem including upper and lower sections having threaded interengagement characterized in that the stem length may be adjusted to control stopper displacement from the seat in response to downward depression of the cap.
Claim 10
Dependent Claim
189 words
