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.
