A bicycle chain lubricant that may be applied as a coating on a bicycle chain is a crystalline solid at ambient temperatures, yet when the chain is in motion the forces around internal components locally transforms the coating to a lubricous fluid. This increases chain efficiency in the drive train and reduces ware by limiting water and dirt access to chain internal components.

A link chain cleaning and lubricating device, and lubricants for use therein.

A lubrication system for a chainsaw, the lubrication system including a reservoir housing a lubricant; a fluid conduit extending between the reservoir and a location adjacent to a chain of the chainsaw; a pump configured to move lubricant from the reservoir to the location adjacent to the chain; and a valve disposed along the fluid conduit, the valve having a lubricant inlet that receives lubricant from the reservoir, an air inlet, and an outlet that provides lubricant to the location adjacent to the chain, wherein the valve is movable between an open position whereby lubricant passes from the lubricant inlet to the outlet and a closed position whereby the outlet is in fluid communication with the air inlet, and wherein the valve moves between the open and closed positions in response to a user input.

Disclosed is a new type of dosing device in a tree-processing device and a method for using it. The dosing device comprises a pump (2) to be attached to the processing device and a feed hose (15) connected to the pump (2) for leading the treatment agent fed by the pump (2) to the point of use. In the device is a replaceable treatment-agent cartridge (7) and the treatment-agent cartridge contains treatment agent. The cartridge is attached to the inlet port of the pump (2) by means of an adapter (4).

The invention relates to a lubricating pump which contains screw pistons of which one is in compression operation and the other is in suction operation in alternation. The invention further relates to a method for supplying lubricant, wherein a first screw piston is in a suction operation while a second screw piston is in a compression operation and vice versa, and wherein the two screw pistons are driven by means of a common gear train, which contains one piston gear for each screw piston.

An engine is described having a crankcase, a liner and a head assembly. The crankcase is split along a plane defining a two part crankcase, where fluid passages are passing through only one of the crankcase portions, so as to not require crossing the split line. A connecting rod also includes a tapered end, and the piston has a complementary carrier receiving the connecting rod.

An object of the present invention is to provide a chain guide that can improve functional properties of a chain drive system. The chain guide of the present invention is attached to an engine block by a mounting bolt and slidably guides a running chain. The chain guide includes a mounting part provided with a shaft hole through which a mounting bolt is passed, and an oil jet passage for injecting lubricating oil, supplied to the shaft hole at a predetermined pressure, toward the chain.

A lubricating tube and a lubrication system are configured to lubricate an apparatus having a rolling component. The lubrication system includes a fluid reservoir containing a fluid, a fluid line coupled to the fluid reservoir; and the lubricating tube, which is disposed between the fluid line and the rolling component. The lubricating tube includes a rigid cylindrical body surrounding a cavity and having an outer circumferential surface. An inlet of the lubricating tube is coupled to the fluid line and provides fluid communication between the fluid line and the cavity. A plurality of ports is disposed on the outer circumferential surface and is configured to dispense the fluid to the rolling component. A location of each port of the plurality of ports from the inlet is customizable.

The present disclosure relates to an arrangement for transferring fluid to a guide bar in a chain saw. A channel can extend from a chain saw body to the fastening arrangement of the guide bar. The channel can include a cavity through the entire channel, a first end of the cavity being connected to a feed channel provided in the chain saw body and a second end thereof to a counter channel provided in the fastening arrangement. The counter channel, in turn, is arranged to extend to the guide bar. The channel is thus arranged to guide fluid flowing in the feed channel provided in the chain saw body through the channel and further through the counter channel provided in the fastening arrangement to the guide bar.
