Abstract:
1. A grease line coupler comprising: a receiver having a body with a cylindrical receiving extension, said receiving extension having an entrance opening, said receiving extension housing a slidable poppet that is spring biased toward said entrance opening so that said entrance opening is normally closed; and a nozzle having a generally hollow body with an exit opening, said body enclosing an immovable poppet that extends to the exit opening, said nozzle body also enclosing and surrounding a slidable, annular poppet seat that is spring-biased toward the exit opening so that it surrounds the immovable poppet, seals the exit opening, and forms, with the nozzle body and with the immovable poppet, an easily cleanable generally planar face when the nozzle is decoupled from said receiver, said body housing an internal ball valve that controls the flow of pressurized lubricating fluid through the nozzle, said ball valve coupled to a rotatable shaft to which an external handle is secured, said valve actuatable with said handle only when the nozzle exit opening is coupled to the receiver entrance opening; wherein the slidable receiver poppet and the receiver body form an easily-cleanable, generally flush face when the receiver is decoupled from the nozzle and the slidable poppet is biased to a forwardmost position so as to seal the entrance opening.
