    Abstract: A cooling gas ventilation chimney is provided for an end region of a dynamoelectric machine having a rotor. A plurality of radial slots are provided in the rotor, and a plurality of coils are seated in the radial slots. The coils form radially stacked turns. The ventilation chimney includes one or more chimney slots that are defined in at least a portion of the radially stacked turns. The chimney slots extend in a substantially radial direction to the rotor, and at least a portion of a surface of the chimney slots is turbulated so as to have a roughened surface profile for enhanced heat transfer.

    Abstract: A particle separator and a pneumatic tool incorporating the same for separating particles from a fluid passed therethrough. The particle separator includes an inlet passageway having an upstream end and a downstream end and an inlet which is in fluid communication with the downstream end of the inlet passageway. A separation passageway is connected to the downstream end of the inlet passageway and connected via a substantially "U"-shaped passageway to a chamber. The inlet passageway, separation passageway, and substantially "U"-shaped passageway are connected in fluid communication to provide a flow path to the chamber. In one embodiment, the chamber of the particle includes a removable plug. In another embodiment, the chamber is vented to provide a bleed-path from the separator passageway to and out of the chamber. Preferably, the bleed-path comprises a labyrinth seal which in a preferred embodiment includes a plug having threads disposed within the chamber.
