A system for harvesting energy from a lubrication event includes a fluid pump, a fluid injector, an energy harvesting device, a wireless transmitter, and a controller unit. The fluid injector receives fluid from the fluid pump. The fluid injector is connected to the energy harvesting device, which is configured to produce electrical energy in response to a firing of the fluid injector. Electrical energy produced by the energy harvesting device powers the wireless transmitter, which is configured to transmit a wireless signal. The wireless signal indicates that the fluid injector fired. The wireless signal is received by the controller unit, which controls the fluid pump.

Provided a die lubricant rotating spray tray device, wherein the nozzles, the connecting sleeve bodies, the nozzle connecting pipes, the air pipe joints and the lubricant pipe joints are sequentially connected to form independently-communicated cavity pipelines, compressed air is input from the air pipe joints, a lubricant is input from the lubricant pipe joints, the rotation driving mechanisms drive the spray tray rotators to rotate through the transmission mechanisms, and the spray tray rotators drive the nozzles to rotate, so that the same dosage of the lubricant is sprayed on the maximum pitch circle surfaces of upper and lower dies, the aim of uniformly spraying the forging lubricant on the working surfaces of the upper and lower dies is achieved.

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.

A fluid system of a machine. The fluid system includes a fluid reservoir, a pump coupled to the fluid reservoir, a filter coupled to the pump and a valve assembly. The valve assembly includes a first port, a second port coupled to the first port and to the fluid reservoir, a third port coupled to the first port, and a first check valve positioned between the first port and the second port. The fluid system further includes a second check valve positioned between the filter and the third port.

The present invention relates to a transportable system for delivering lubricant to a target, more specifically for lubricating machine parts and/or for re-filling a central or a de-central lubricating system. Further, the present invention relates to parts of the transportable system, the parts being a pressure releasing coupling, a gear pump and/or a high pressure pump.
