Abstract: In a water dispenser water-outlet assembly for a refrigerator, the water-outlet assembly includes a housing disposed in a side wall of the refrigerator body; a water-outlet switch and a trigger mechanism are included in the housing, and the trigger mechanism includes a triggering member and a driving member; the driving member is configured to drive the triggering member to one-dimensionally slide in a direction parallel to the side wall; the triggering member is slidably connected to the housing, and the triggering member is configured to one-dimensionally slide in a direction parallel to the side wall to trigger the water-outlet switch when it is driven by the driving member. The water dispenser water-outlet assembly of the present disclosure can be used in a water dispenser in a refrigerator.

Abstract: A yoke-trunnion universal joint has a plastic anti-wear coating disposed between the sleeve and trunnion for lubrication, anti wear and absorbing vibration. A combining means combines the plastic anti-wear coating with sleeve or trunnion tightly. The plastic anti-wear coating is made by nylon or polytetrafluoroethylene. The universal joint has a simple structure, long working life, low operating noise and cheap manufacture cost. The most advantage is that the universal joint needs not oil or grease for whole working life. It is an oil or grease free and maintenance free universal joint.

Abstract: A yoke-trunnion universal joint includes a universal joint body, a cup and an anti-wear coating. The universal joint body has a trunnion nose. The cup has an inner wall surface defining an internal cavity sized to slidably receive the trunnion nose. The anti-wear coating is disposed between and in contact with the trunnion nose and the inner wall surface of the cup when the trunnion nose is received by the internal cavity of the cup.
