A rotary multiport greasing valve having an outer sleeve and an inner sleeve within the outer sleeve. The outer sleeve has at least one inlet port and at least 2 outlet ports. The inner sleeve has an inlet port, a central passageway, and an outlet port. The inner sleeves inlet port is fluidly connected to the outer sleeve's inlet port. The inner sleeve rotates within the outer sleeve so that the inner sleeves outlet port is circumferentially aligned with a selected outer sleeve outlet port creating a fluid pathway from the outer sleeve inlet port into the inner sleeve's inlet port through the central passageway through the inner sleeve's outlet port and finally through the outer sleeves outlet port to create an open flowpath. In certain instances, the inner sleeve inlet port is longitudinally shifted so as not to align with any portion of an outlet sleeve outlet port.

An auxiliary oil supply apparatus for a rotating device (50, 51), the rotating device comprising a primary oil supply (52), a rotating component (50) and a static component (51) situated radially outwardly of a centre of rotation of the rotating component (50) and arranged to collect oil (58) held radially outwardly from the rotating component (50) as the rotating component rotates. The auxiliary oil apparatus comprises a scoop (56) associated with the rotating component (50) and is responsive to a change in a known parameter to move between a first position in the static component (51) to a second position between the static component (51) and the centre of rotation.

An assembly for rotational equipment includes a stationary structure and a rotating structure. The stationary structure is configured with a first fluid conduit. The rotating structure is configured with a second fluid conduit and a fluid scoop for the second fluid conduit. The second fluid conduit is fluidly coupled with the first fluid conduit through an annular plenum formed by and radially between the stationary structure and the rotating structure. The fluid scoop projects radially into the annular plenum.

A transmission shaft assembly for a rolling stand for use in a metal rolling mill is provided. The transmission shaft assembly transmits lubricant through the assembly. The transmission shaft assembly includes a shaft having an outer periphery and defining a centrally positioned longitudinal opening extending from a first end to an opposed second end of the shaft. The shaft defines a plurality of internal passageways in the shaft. The transmission shaft assembly also includes a rotary distributor mounted on the outer periphery of the shaft. The shaft assembly provides a conduit for the lubricant through the plurality of internal passageways in the shaft.

A lubricant distributor of a lubrication system configured to lubricate one or more components of a passenger conveyor is provided including a housing having an input opening, a plurality of output openings and a shaft opening. A valve stem including a bore and a plurality of lubricant outlets is generally arranged within the shaft opening. The bore is configured to fluid couple the input opening to each of the lubricant outlets. Each lubricant outlet is associated with and configured to provide lubricant to at least one of the plurality of output openings at a distinct position of the valve stem. The lubrication system may include multiple lubricant distributors connected by a lubrication fluid circuit having a pump, motor and lubricant source.

A system for dispensing lubricant in a stream of cool air to a work piece and a machine tool. A source of lubricant and cool air are coupled to a stationary coupler. A rotating turret includes a plurality of machine tools mounted thereon and the plurality of rotating couplers mounted thereon. Each machine tool is associated with or coupled to one of the rotating couplers. The turret rotates so that a rotating coupler is in abutting engagement with the stationary coupler. Lubricant and cool air pass through the stationary coupler to the rotating coupler, which delivers the lubricant and cool air to a nozzle that is directed at the machine tool associated with the rotating coupler.
