Abstract
A nipple-type drinker for fowl and small animals with a self-contained valve assembly that can be inserted in and removed from the drinker as a single unit is disclosed. The drinker includes a valve chamber with a metering pin, valve member, and valve seat therein. The valve seat is a metal, annular member that is press-fit into the valve chamber. When the seat is positioned in the chamber it prevents the metering pin and valve member from falling out. Thus, a self-contained valve assembly is provided. The valve assembly is telescopically mated with a housing as a single unit. The housing includes a trigger pin and-an outlet for fluid. The housing further includes a stop that works in conjunction with a lip in the valve chamber to align the valve seat when the drinker is assembled.
