Abstract
A seal member for use in a pellet dispensing apparatus which can provide a barrier between a rotor member and a supply hopper so that gas emitted from the supply hopper will not escape. The seal arrangement also serves the function of a spacing or biasing member for a drive gear as well as a bearing surface. The seal member is disposed in a manner that it will selfadjust during wear yet is flexible to withstand contact with debris. Preferably the seal unit is fabricated from a fluorocarbon resin and is frusto conical in shape.
