a primary lip seal disposed about the rotatable shaft and axially offset from the non-contact seal on the downstream axial side, the primary lip seal having a protruding lip extension that is turned to point to the downstream axial side of the non-contact seal;
a vent structured to receive the fluid located between and in contact with the non-contact seal and the primary lip seal after the fluid having traversed the annular space, the vent configured to return the fluid to the fluid moving component;
a secondary lip seal disposed about the rotatable shaft and adjacent to the primary lip seal, the secondary lip seal including a protruding lip that extends toward the primary lip seal; and
an atmospheric vent in fluid communication with a space between the primary lip seal and the secondary lip seal.

AIR COMPRESSOR DRYER FILTER

Ingersoll-Rand Company, ...

1. An apparatus comprising:a gas compressor system having conduit for the passage of compressible gas and a compressor component with a gas intake and a gas outlet where a mass flow of the compressible gas that flows from the gas intake through the compressor component and out the gas outlet also flows through a gas dryer structured to remove moisture from a compressed form of the compressible gas, the gas compressor system also including a frustoconical shaped filter assembly having a first narrow end of a frustoconical shape structured to pass filtered compressible gas and a second wide end of the frustoconical shape structured to receive unfiltered compressible gas, the frustoconical shaped filter assembly disposed in the conduit wherein the filter includes a retainer housing only a single frustoconical shaped filter media, and wherein the single frustoconical shaped filter media is a mesh filter and is disposed internal to a retainer, the retainer providing structural strength to the mesh filter and extending between the first narrow end and the second wide end.

GAS COMPRESSOR FILTER ELEMENT

Ingersoll-Rand Company, ...

1. An apparatus comprising:a compressed air filter element configured to filter mixed stream of compressed gas and oil mist, the compressed air filter element having:
a basket having an interior into which a filter media is located when installed, the basket including an exterior shell having a plurality of apertures into which flow the mixed stream of compressed gas and oil mist;
a lip located at an end of the basket and structured to engage a lid of a filter container, the lip oriented transverse to the exterior shell of the basket and having a circumferentially extending surface around the interior of the basket and having a portion located in a plane of capture used to support the compressed air filter element when in an installed configuration; and
a separator element flange directly connected to the lip and to the exterior shell and not otherwise extending past the exterior shell, the separator element flange located entirely on one side of the plane in which is located the portion of the circumferentially extending surface of the lip, the separator element flange including a surface forming a flow path that descends from the lip to the interior of the basket such that a liquid forming on the separator element flange is urged to flow into the interior of the basket.

COMPRESSOR THERMAL VALVE UNIT TO ROUTE LUBRICANT USED IN A COMPRESSOR

Ingersoll-Rand Company, ...

1. An apparatus comprising:a compressor thermal valve unit having:
a thermal valve housing having an exterior shell that includes a plurality of apertures through which a first fluid can traverse, the housing enclosing an interior having a plurality of passages in fluid communication with the plurality of apertures and through which the first fluid from the apertures can pass;
a base disposed near an end of the thermal valve housing and structured to support the thermal valve when affixed to a compressed air system pipe, the base having a thickness that extends from a bottom surface and a footprint defined in part by a lateral length, the bottom surface of the base having a shape complementary to an external side surface of the pipe, wherein the thickness is shorter than the lateral length, and wherein the lateral length extends along an axial direction of the pipe; and
a thermal valve having a valve body coupled to a thermally responsive element, the thermally responsive element in thermal contact via intermediate structure or directly exposed to compressed air which traverses the compressed air system pipe during operation, the thermally responsive element configured to directly assess temperature of the compressed air, the valve body structured to move in response to excitation of the thermally responsive element from a temperature of the compressed air so as to open and close one or more of the plurality of passages within the thermal valve housing for the passage of the first fluid.
