A cam follower assembly includes a shaft having a body defining a flanged head having an outer bearing surface extending therefrom. An outer ring is positioned around the shaft thereby forming an annular space there between. A plurality of rollers is positioned in the annular space. A channel extends through the shaft and branches radially outward at an outlet to communicate with the annular space. A lubrication assembly is positioned in the shaft and includes a pressurizing device located upstream of a lubrication reservoir and a metering device positioned downstream of the lubrication reservoir. The lubrication reservoir is in fluid communication with the outlet. The lubrication assembly includes a membrane positioned downstream of the lubrication reservoir. A piercing device is positioned proximate the membrane to pierce the membrane and release a lubricant from the lubrication reservoir.

A sealing assembly includes retaining clips fit within grooves in a throat disposed between a fluid chamber and a working fluid cylinder. The retaining clips define individual seal glands, and seals and spacers are disposed within the seal glands. A piston rod passes through the throat seal, and the throat seal provides a seal against lubricant pressure from inside the fluid chamber and working fluid pressure from inside the working fluid cylinder.

A pump with a reservoir of a lubricant, including a hollow body in which a piston, loaded by a pressing element, sealingly slides, at least a port for loading the lubricant in a compartment defined by the inner wall of the hollow body and by the piston, and at least a valve for exhausting air trapped in the compartment together with the lubricant during a loading step.

A handheld work apparatus has a drive motor which drives a tool of the work apparatus. A lubricating arrangement is provided for the tool. The lubricating arrangement includes a lubricant piece that is solid at 20 C. The work apparatus has a melting chamber into which the lubricant piece projects and which is connected to the tool via at least one lubricant channel. The melting chamber is delimited at least partially by a heat conducting element which is heated during operation of the work apparatus.

A smart system for oil delivery including a dispenser assembly, a pressure supply assembly, a gearbox assembly, and an electronic assembly. The dispenser assembly including a dispenser. The dispenser being an enclosure with a hollow interior with a valve located at one end. The hollow interior of the dispenser defining a reservoir for the storage of oil or other lubrication fluids. The interior of the dispenser further including a pressure supply assembly. The pressure supply assembly including a spring and a plunger that are oppositely located with respect to the valve within the interior of the dispenser. The electronic assembly includes a flow meter, a solenoid valve, and a microcontroller unit. The electric valve being actuated by the microcontroller unit to allow the pressure supply assembly to expel oil stored within the reservoir via the valve.

A lubricator for a plunger lift system includes a tubular body, a bumper housing, a bumper sub, a first spring, and a second spring. The bumper housing is disposed in the tubular body and has a chamber, a lower end, and an upper end. The lower end is open to receive an upper end of a shift valve of a bypass plunger. The bumper sub has a lower end and an upper end and is slidably disposed in the chamber of the bumper housing. The first spring is disposed in the chamber to absorb an impact force applied to the bumper sub by the shift valve. The second spring is disposed in the tubular body to absorb an impact force applied to the lower end of the bumper housing by a plunger body of the bypass plunger.
