A modular digital filter, regulator and lubricator (FRL) connector and system are provided. The modular digital filter, regulator and lubricator connector and system are especially suitable for use in improving compressed air quality so as to extend the life of tools and machines which are connected to the FRL devices. The connector device and system allows for a quick and efficient connection with respect to both electronics and air lines and reduces problems that arise from wire pig-tailing or accidental disconnection of the FRL. The device and system may have digital, visual and audible warnings with respect to the quality of air passing through the system and to the tools and machines.

A compressor is disclosed which can include a first stage and a second stage. In one form the compressor includes contact cooled compressor stages. The compressor can include a rod useful to inject a lubricant for purposes of cooling/lubricating/sealing the rotating components of the compressor. In one form the rod is an elongate rod with openings which permit a lubricant such as oil to be injected. The injected oil can be atomized via the openings. The rod can be positioned in the interstage space between the first and second stages, and can include a variety of openings.

A gas turbine engine includes a fan shaft diving a fan having fan blades. A gear system includes a sun gear surrounded by a plurality of intermediate gears. A carrier at least partially supports the plurality of intermediate gears. A ring gear surrounds the plurality of intermediate gears. The sun gear is driven by a turbine. At least one fan shaft support bearing is located forward of the gear system. A coupling fixes the ring gear from rotation relative to an engine static structure. A lubrication system lubricates components across a rotation gap. The lubrication system includes a lubricant input. A stationary first bearing receives lubricant from the lubricant input and has a first race in which lubricant flows. A second bearing rotates within the first bearing. The second bearing has a first opening in registration with the first race such that lubricant may flow from the first race through the first opening into a first conduit.

The present disclosure is directed to a screw compressor system having a compressor housing with a pair of screw rotors rotatably supported within a compression chamber. A lubricant port is in fluid communication with the compression chamber. A nozzle insert having a longitudinal body extending between a first end and a second end can be positioned within the lubricant port. A swirl chamber formed by the nozzle insert or tangential flow into an offset lubricant port is configured to generate an atomized lubricant flow and discharge the atomized lubricant into the compression chamber.

A generator of air/oil mist includes an accumulation chamber for a mist of particles of oil in air, and equipped with a first mist outlet and a nebulizer feeding into the accumulation chamber, the nebulizer including a first nozzle supplied with pressurised air, which features at least a first channel supplied with the pressurised air, each channel being equipped with an outlet on a surface of the first nozzle partially defining a first chamber axially symmetrical with respect to an axis, the channels being positioned to generate a rotation of the air fed into the first chamber around the said axis, the surface of the first nozzle featuring a section converging towards an outlet hole, the nebulizer featuring a second nozzle supplied with oil and feeding out into the first chamber so that the oil is suctioned via the second nozzle because of the air flowing through the first chamber.
