Abstract
An animal feeder includes a feed reservoir having a cavity for holding a feed material, and a feed dispensing assembly coupled to the feed reservoir. The feed dispensing assembly includes a check valve to allow selective access to the feed material. The check valve inhibits feed leakage from the feed reservoir during pressure fluctuations within the feed reservoir.
