Abstract
Abstract An animal feeding valve through which an animal (e.g. in a cage) can draw liquid from a supply to which the valve is connected, comprises a valve head disposed at the supply side of a valve seat and biassed against the seat by a spring at said supply side, a valve stem on the valve head extending through the seat, and an outlet cylinder surrounding the stem, the end of the valve stem being exposed at the end of the cylinder so that when an animal applies its mouth to the latter it can move the end of the stem sideways to open the valve; the extent of the sideways movement is regulated by an annular member which is mounted within the cylinder for axial adjustment therealong and through which the stem extends.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
140 words
In an animal feeding valve comprising a body, a liquid inlet port and a liquid outlet spout defined by the body, a valve seat in the body between the liquid inlet port and the liquid outlet spout, a valve closure member biased towards the spout against the valve seat so as to close the spout from the inlet port and an arm extending through the spout and fixed to the valve closure member so that angular movement of the arm tilts the valve closure member relative to the seat to open the valve, the improvement of: a control member mounted in the spout for adjustment therealong, an annular wall being defined around the arm by the control member and serving variably to limit angular movement of the arm, according to the adjustment position of the control member in the spout.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
22 words
An animal feeding valve according to claim 1, wherein the control member is screw engaged within the spout to permit said adjustment.
Claim 4
Dependent Claim
40 words
An animal feeding valve according to claim 1, including a shoulder in the body, and a spring acting on the shoulder and the inlet side of the valve closure member so as to bias the latter against the valve seat.
Claim 5
Dependent Claim
21 words
An animal feeding valve according to claim 1 including a filter positioned between the inlet port and the valve closure member.
