A lubricant injector includes a body having an inlet at a first end fluidly coupleable to a lubricant source, an outlet, a delivery chamber coupled with the outlet and a bore defined by a substantially circular inner surface with a constant inner diameter and spaced axially from the body inlet, the bore having a first port fluidly connected with the body inlet and a second port disposed between the body inlet and the first port and fluidly connected with the delivery chamber. A generally circular cylindrical piston is disposed within the bore so as to divide the bore into an operating chamber fluidly coupled with the first port and a measuring chamber fluidly coupled with the second port and located axially between the operating chamber and the body first end. The piston has an outer circumferential slidably disposed against the bore inner surface and having a generally constant outside diameter.

A packaged oil delivery with integral flow restrictor including a dispenser assembly and a restriction assembly. The dispenser assembly includes a dispenser that is to be mounted on a mechanical system to enhance lubrication of gears, bearings, shafts, seals, and the like. As elements of mechanical systems often rotate at high/low RPM, the channels are intended to slow/expedite the speed in which oil is passively delivered onto the aforementioned components. The restriction assembly includes channels internally disposed within the dispenser to passively meter the flow of oil being expelled. The speed with which the oil is expelled from the inside of the dispenser is directly related to the length and pattern that the channel has.

A flow restrictor assembly includes a threaded element and a sleeve. The threaded element defines a plurality of threads that extend from a first threaded element end towards a second threaded element end. The sleeve has an inner sleeve surface that engages edges of a portion of the plurality of threads and extends between a first sleeve end and a second sleeve end. A lubrication flow path is defined by the portion of the plurality of threads and the inner sleeve surface and is arranged to create a pressure drop in a lubricant that flows through the lubrication flow path.

The present disclosure relates to a device for lubricating an internal combustion engine having a crankshaft, which is connected to at least one connecting rod. The device has at least one first flow limiter, in particular a restrictor, for reducing a lubricating fluid flow of a lubricating fluid stream passed to the at least one first flow limiter. The device has a plurality of crankshaft bearings for the rotatable support of the crankshaft, wherein the plurality of crankshaft bearings is provided in fluid communication downstream of the at least one first flow limiter. The device has at least one big end bearing for the rotatable support of the at least one connecting rod, wherein the at least one big end bearing is provided in fluid communication downstream of at least one crankshaft bearing of the plurality of crankshaft bearings.

Systems and methods for dispensing lubricant, of which the systems include a grease gun including an outlet. The grease gun is configured to eject lubricant into a machine through the outlet. The grease gun also includes a sensor configured to sense an amount of the lubricant ejected through the outlet, and a communication module in communication with the sensor and configured to transmit first data representing the amount of lubricant ejected through the outlet. The systems further include an intermediary computing device in communication with the communication module, the intermediary computing device being configured to receive the first data from the communication module, transmit the first data to a remote server, and receive second data representing a maintenance action to take on the grease gun, the machine, or both from the remote server.
