System and method for applying lubricant onto a surface
A system and method for applying lubricant to a surface, such as a heating surface of a fuser member. The system includes lubricant conduit for carrying pressurized lubricant toward a spraying assembly. A heating element surrounds the lubricant conduit and heats the pressurized lubricant before it arrives at the spraying assembly. The system also includes a pair of double O-ring sealing assemblies for sealingly coupling a lubricant tube to the system.
1. A system for applying a lubricant to a surface, the system comprising:
a lubricant conduit including an input end for receiving lubricant, an output end, and a heating element between the input end and the output end;
an applicator fluidly coupled to the output end to receive heated lubricant therefrom and operating to apply the heated lubricant to the surface;
a receiver chamber for receiving a supply of the lubricant, the receiver chamber including an insertion end configured to receive the supply of lubricant and an output end opposite the insertion end; and
a pusher member positionable within the supply of the lubricant for applying pressure to the lubricant, the pusher member including a pressure face facing away from the lubricant and toward the insertion end when the supply of lubricant is received by the receiver chamber;
wherein the pusher member includes a through opening and a pressure release member associated with the through opening and moveable between a sealed position and an unsealed position for venting the through opening.
2. The system of claim 1 , wherein the heating element substantially surrounds the lubricant conduit.
3. A system for applying a lubricant to a surface, the system comprising:
a lubricant conduit including an input end for receiving lubricant, an output end, and a heating element between the input end and the output end; and
an applicator fluidly coupled to the output end to receive heated lubricant therefrom and operating to apply the heated lubricant to the surface;
wherein the input end includes a coupling member having a generally cylindrical sealing portion, the sealing portion including a first sealing member having an axially facing sealing portion and a second sealing member having a radially outwardly facing sealing portion.
4. The system of claim 3 , wherein the coupling member defines an axially opening circumferential groove that receives the first sealing member and a radially outwardly opening circumferential groove that receives the second sealing member.
5. The system of claim 3 , further comprising a receiver chamber for receiving a supply of the lubricant, the supply of the lubricant including a discharge end, and wherein the first sealing member sealingly engages an annular end surface of the discharge end and the second sealing member engages an inner cylindrical surface of the discharge end when the supply of the lubricant is installed in the receiver chamber.
