Abstract: A driveline power transmitting component having a power transfer assembly disposed in a housing. The housing defines a vent aperture and a sump. A lubricating fluid is disposed in the sump and portions of the power transfer assembly travel through the lubricating fluid so that a lubrication surge zone and a splash lubrication zone are formed. The vent aperture is disposed in at least one of the surge zone, the splash lubrication zone and the sump when the driveline power transmitting component is disposed in at least one orientation in a predetermined range of operating positions in which the driveline power transmitting component can be operated. A breather relocation conduit is employed to permit air to be vented from the housing to the vent aperture without intaking lubricating fluid into the breather relocation conduit.

Abstract: A transfer case having a chain drive disposed in a housing. The housing defines a vent aperture and a sump. A lubricating fluid is disposed in the sump and portions of the chain drive travel through the lubricating fluid so that a lubrication surge zone and a splash lubrication zone are formed. The vent aperture is disposed in at least one of the surge zone, the splash lubrication zone and the sump when the transfer case is disposed in at least one orientation in a predetermined range of operating positions in which the transfer case can be operated. A breather relocation conduit is employed to permit air to be vented from the housing to the vent aperture without intaking lubricating fluid into the breather relocation conduit.

Abstract: Interconnected vents for a motor vehicle axle assembly, transmission or transfer case which interconnects multiple vents at different locations together with another vent positioned at the highest point the lubricant travels. This allows the lubricant to flow out of one vent and return to the other vent without leaking onto the ground. Such an interconnected vent arrangement will minimize the extent of external lubricant leakage due to such factors as foaming of the lubricant, air entrapment in the lubricant, volumetric expansion of the lubricant due to elevated operating temperatures, pumping or splashing of the lubricant by internal rotating or moving parts, flow of the lubricant due to tilting of the motor vehicle, and thus the motor vehicle axle assembly, transmission and transfer case, and/or acceleration or deceleration of the motor vehicle.

Abstract: An adjustable oil metering valve for a compressed air lubricator includes a lower, fixed member (20) having a central, downwardly extending oil delivery nozzle (30) and a peripherally ramped upper surface (29) in communication with the nozzle (30). Seated on the surface (29), and rotatable relative thereto, is a valve member (21) that includes a lower disc portion (31) having a radial channel (35) formed in its lower surface. The lower surface of the rotatable disc portion (31) and the upper surface (29) of the fixed member (20) thereby define between them a peripheral gap (H) of progressively varying height into which the oil is fed whence it flows to the nozzle (30) via the channel (35). The rate of flow of oil to the nozzle (30) is substantially proportional to the height of the gap (H) at the angular location of the outer end of the channel (35) which may be selectively varied by rotating the valve member (21).

Abstract: An airline lubricator characterized by the provision of a backstop which limits and controls the contour of the lubricator's flow restricting elastomeric flapper, whereby higher flow capacities may be achieved without sacrificing flapper service life, and by a sight tube seal plate that supplies lubricant to and from the sight tube via respective passages at least one of which has opposite ends thereof configured for communicating with transversely offset passages in the body of the lubricator head.

Abstract: The cooling method consists of sucking up inside the reduction gear previously filtered air which, when traversing the reduction gear, is mixed with the spray of lubricating oil so as to collect its calories and reject it outside after having purified it from the oil it contains. The equipment incorporates one or several air intakes provided with filters and an extraction fan driven by the reduction gear and provided with means for collecting and draining the oil. The application of this method is for reduction gears lubricated with sprayed oil and particularly for helicopter gearboxes.
