ABSTRACT:
A structurally simple and inexpensive valve enables caged small animals to obtain water on demand by moving the tip of a rod which protrudes from an end of the valve. An annular valve body has a first end fitted into one end of a tube and an opposite end forming a valve seat that faces away from the tube. The rod extends through the tube and through an opening at the center of the valve seat and into a moveable sleeve which seals the opening when the valve is in the closed condition. Resilient material extends between the valve body and movable sleeve to support the sleeve and rod and to bias these components towards their opening sealing position. At least the portion of the rod which extends within the valve seat opening is of smaller diameter than the opening thereby enabling opening of the valve by pivoting movements of the rod as well as by axial movement of the rod. The inlet end of the valve may be situated within the outlet spout of an animal water bottle or other water source.
