A lubricating system has a pump to force a viscous lubricant from a supply of lubricant to a lubricator at which the lubricant is to be dispensed onto a cable, wire, or the like that is being pulled through a conduit. A sensor, associated with a spool from which the cable is being dispensed, is be used to automatically control the amount of lubricant that is to be dispensed onto the cable. A second described system comprises a custom bucket or bucket insert which allow a cable to pass through the bucket whereupon lubricant will be automatically applied to the cable and the container includes a profiled base to ensure proper passage of the cable through the lubricant and ensure the maximum usage of any lubricant.

A minimal lubrication device including a lubricating fluid storing tank, conduit for supplying the lubricant pressurized to at least one modular element. The at least one modular element including a lubricating fluid conduit intercepted by flow regulator and compressed air conduit, such conduits fluidically connected to air and lubricant mixing element. The flow regulator including a shutter that can be at least partially housed in calibrated hole and movable between upper and lower stroke position ends. The calibrated hole in fluid communication, on one side, with pressurized lubricant delivery and, on the other side, with the mixing element. The shutter having at least one conical profile portion insertable in the calibrated hole. The conical profile portion has a surface groove facing a surface defining the calibrated hole at least when the shutter is in an intermediate position between the lower and upper stroke position ends.

A progressive distributor for lubricant includes a housing block having an inlet and a plurality of outlets and a plurality of metering pistons received in associated piston bores in the housing block. Each piston bore is associated with two lubricant outlet bores, and each metering piston is displaceable and configured to alternatingly release the one or the other lubricant outlet bore in order to dispense the metered lubricant amount to the lubricant outlet bore. The piston bores are fluidically connected to the lubricant inlet bore and to each other via connecting bores in order to transfer lubricant to the other piston bores. A dummy piston is disposed in one of the piston bores that permanently closes both the lubricant inlet bore and both lubricant outlet bores, and includes at least one bypass passageway that fluidically connects two of the connecting bores to each other.

A lubricant metering device includes a cup-shaped body with a supply passage coupled to a valve element, a hollow tubular body with a free end facing the valve element, a piston slidingly sealed inside the cup-shaped body and along an external surface of the tubular body, an elastic element exerting a load on the piston towards the supply passage, delineating an accumulation chamber facing the valve element and a dispensing chamber in constant communication with the cavity of the tubular body, also in communication with a delivery passage, the valve element closing the free end of the tubular body, isolating the cavity from the accumulation chamber and allowing communication with the supply passage, or isolating the accumulation chamber from the supply passage and allowing communication with the cavity. A stop limits the piston stroke towards the elastic element to adjust the dispensing of lubricant.

A coupling element for a machine tool attachment, having a coupling section for detachable mounting on a tool interface of a machine tool and having a connection for attaching a container for media that has an outlet and holds a medium. In addition, a machine tool attachment, a machine tool, and a method for delivering a medium to a part of a machine tool is provided.

There is provided a bearing lubrication application control system which comprises a digital controller device operably coupled to a lubrication meter and a computer readable medium reader. As such, during lubrication application, the digital controller device is configured for reading bearing data from bearing computer readable media associated with each bearing and also recording an applied lubrication volume for each of the bearings. As such, for a subsequent lubrication application, the digital controller device is configured for calculating a dynamic lubrication schedule for each of the bearings wherein the schedule comprises at least an appropriate lubrication volume to be applied calculated at least according to the stored apply lubrication volume for each of the plurality of bearings.

An oil restrictor for emergency lubrication of a component for an aircraft turbine engine includes a metal cylindrical body having a longitudinal axis and configured to be housed in and shrink-fitted into a cylindrical bore of a part of the turbine engine. The restrictor further includes an integrated oil circuit enabling oil to pass through the restrictor along the axial extent thereof. The body is a one-piece body, and the circuit has at least two oil channels recessed on an outer cylindrical surface of the body and extending around and/or along the axis.

A lubricant injector includes a body having an inlet fluidly coupleable to a lubricant source, an outlet, and an elongated bore extending along an axis and having an outer end proximal to the body second end, a closed inner end spaced axially from the body first end, a first port, and a second port disposed generally between the bore closed end and the first port. A delivery chamber separate from the bore has an inlet port and an outlet port fluidly coupled with the body outlet. A piston disposed within the bore divides the bore into an operating chamber coupled with the first port and a measuring chamber coupled with the second port. The operating chamber is fluidly coupled with the inlet and the measuring chamber is located between the bore closed end and the operating chamber and is fluidly coupleable with the inlet and alternatively with the delivery chamber.
