The following disclosure relates to a conduit lubricating device. The conduit lubricating device includes a lubricant reservoir, a hose with a stiffness great enough to enable manual insertion into a populated conduit, yet not so great as to prohibit traversal of the conduit's contours, and a pump fluidly coupled to the lubricant reservoir and the hose.

An oil nozzle assembly includes a nozzle body and a nozzle insert. The nozzle body includes a main portion, a tip portion, a collar, and a lip. The tip portion is connected to the main portion. The collar is positioned at an interface between the main portion and the tip portion. The lip extends radially outward from the tip portion and includes an outer diameter. The nozzle insert includes a sleeve, an endwall connected to the sleeve, an orifice, and a retention element. The orifice is disposed in the endwall and is fluidly connected to the tip portion of the nozzle body. The retention element extends radially inward from the sleeve. A portion of the retention element includes an inner diameter that is less than the outer diameter of the lip.

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.

Various embodiments of valve assemblies are provided for use in connection with the fluid systems of machines such as engine-powered machines. The valve assemblies may be used for performing fluid refill operations, fluid evacuation operations, fluid purge operations, and other types of fluid operations in connection with machine maintenance.

A lubricant delivery system and method includes a valve manifold, an electronic controller, and a pressure sensor for determining whether there is adequate lubricant flow in the system. The valve manifold receives lubricant from a pressurized source. The valve manifold includes a plurality of valves configured to control the flow of lubricant to respective applicators. The electronic controller controls the opening and closing of the valves. The pressure sensor measures lubricant pressure in the valve manifold, and outputs a signal to the electronic controller. The signal correlates to a lubricant pressure value in the valve manifold. The electronic controller uses the lubricant pressure values to derive an indication of lubricant flow (via the valves) to the applicators.

The following disclosure relates to a conduit lubricating device. The conduit lubricating device includes a lubricant reservoir, a hose with a stiffness great enough to enable manual insertion into a populated conduit, yet not so great as to prohibit traversal of the conduit's contours, and a pump fluidly coupled to the lubricant reservoir and the hose.

An orifice component for a lubrication system may include an orifice head having an outlet orifice and one or more inlet passageways in fluid communication with the outlet orifice. The orifice component may include an orifice stem extending from the orifice head. The orifice stem may have a solid structure.
