A sectional lubricant distributor for distributing lubricant to at least one lubrication point, including a distributor body having an inlet opening for lubricant which is fluidically connected to at least one outlet passage, which opens into an outlet opening of the distributor body, a rotary valve is rotatably mounted in the distributor body and is adjustable between an open position of the rotary valve, in which the outlet passage is open in order to allow lubricant to pass through to the outlet opening, and a closed position of the rotary valve, in which the outlet passage is closed, an electromotive drive which is coupled to a control gear, including a control gearwheel having a control toothing section engageable with a toothing of the rotary valve to move the rotary valve between the open position and the closed position. Further, a method for distributing lubricant to at least one lubrication point.

A saw guide for a saw arbor guide assembly comprises a head, a body, and one or more passages. The head has one or more intake channels adapted to supply lubricant to the saw guide. The body is connected to the head, with the body located between adjacent ones of the saw blades. The body has first and second faces, with the body further having a plurality of lubricant openings located on one or both of the first and second faces for supplying the lubricant to the saw blades. The passages extend through the head and the body and connect each of the intake channels with the lubricant openings, with the passages configured to carry lubricant from the one or more intake channels to the lubricant openings. For each of the lubricant openings, a flow control valve is located in the passage proximate to the lubricant opening to control a flow of lubricant through the lubricant opening. The flow control valves are configured to differentially control the flow of lubricant to the lubricant openings.

A lubrication circuit comprising an oil tank (4) integrated into a first lubricated chamber (5) comprises an evacuation conduit (20) on a recovery conduit (10) from lubricated chambers of the circuit leading to the reservoir (4), opening up into an outlet (21) when an excessive pressure in the tank, that is a symptom of progressive filling, is reached. Application to aircraft engine lubrication circuits, particularly to guard against fuel leaks in the lubricant as a result of a defective heat exchanger.

A device and method for dispensing a friction-coefficient-optimizing mixture of at least one lubricant and at least one grit into the gap between a rail wheel of a rail vehicle and a rail. The device includes a reservoir for the lubricant, a reservoir for the grit, a metering unit for metering the lubricant, a metering unit for metering the grit, a delivery apparatus for delivering the lubricant, a delivery apparatus for delivering the grit, and a common dispensing nozzle. The apparatus for delivering the lubricant and the apparatus for delivering the grit are separate from each other and end in the common dispensing nozzle, the friction-coefficient-optimizing mixture therefore not being formed until the dispensing, and an additional compressed air line is provided, which ends in the common dispensing nozzle.

An autofill shutoff valve includes a valve body mounted to a lubricant reservoir and secured to a fill tube extending into the reservoir. The autofill shutoff valve has a valve stem extending through the valve body and into the lubricant reservoir. The valve stem is actuated by a plate disposed within the reservoir from a first position, wherein lubricant flows from a lubricant inlet to a lubricant outlet through the valve body, to a second position, wherein the valve stem blocks the flow of lubricant through the valve body. The autofill shutoff valve provides lubricant directly to the reservoir, thereby eliminating external plumbing and the autofill shutoff valve also prevents overfill of the reservoir by cutting off the flow when the reservoir is full.

A vent valve for an actuator disposed in a lubricant reservoir includes a bore extending through the plate, a seal disposed within the bore proximate a top surface of the plate, a retaining member extending about a lower opening of the bore, and a ball disposed within the bore between the seal and the retaining member. The vent valve is configured to allow air to pass from a lower portion of a lubricant reservoir as lubricant fills the lower portion. The vent valve also allows air to pass to the lower portion of the lubricant reservoir as lubricant is dispensed from the reservoir. The vent valve closes when the lubricant level reaches the vent valve, thereby preventing lubricant from flowing through the vent valve. The sealed vent valve allows the actuator to rise in response to a rising lubricant level.

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.

A centerfill assembly for a lubricant reservoir includes a hollow tube for receiving lubricant from the top of the reservoir and loading the lubricant into the reservoir near the bottom of the reservoir. Loading the lubricant near the bottom of the reservoir introduces lubricant near where the stirring paddles mix the lubricant and near where the lubricant is loaded to the lubricant pump. Adding the lubricant near where the pumps load and near the stirring paddles helps to eliminate air pockets in the lubricant. In addition, having the centerfill rod minimizes exterior plumbing and allows for the mounting of valves on the fill line.

A protection mechanism for a lubricant reservoir is mounted within a valve protection chamber disposed on an actuator. The protection mechanism includes a valve actuating plate and an elastic member biasing the valve actuating plate upwards. The actuator is pushed upwards by a rising level of lubricant as the lubricant reservoir is filled. When the reservoir is full, the actuator causes the valve actuating plate to contact a valve stem. The valve actuating plate pushes the valve stem up to shut off a flow of lubricant to the reservoir through the shut off valve. During an overfill event the actuator shifts upward due to the rising level of the lubricant in the reservoir. As the actuator shifts upward, the elastic member compresses such that valve actuating plate remains static relative to the lubricant reservoir as actuator rises.

The invention relates to a lubricant distributor, in particular a sectional distributor, for distributing lubricant to at least one lubrication point, comprising a distributor body having an inlet opening for lubricant which is fluidically connected to at least one outlet passage, which opens into an outlet opening of the distributor body, a rotary valve which is rotatably mounted in the distributor body and which is adjustable between an open position of the rotary valve, in which the outlet passage is open in order to allow lubricant to pass through to the outlet opening, and a closed position of the rotary valve, in which the outlet passage is closed, a drive, in particular an electromotive drive, which is coupled to a control gear, comprising a control gearwheel having at least one control toothing section engageable with a toothing of the rotary valve to move the rotary valve between the open position and the closed position. In addition, the invention relates to a method for distributing lubricant to at least one lubrication point.
