Abstract:
1. A power tool comprising: a tool housing including first and second housing members, each including interior and exterior surfaces; a motor disposed in the tool housing and including a motor housing having an external surface and air inlet vents for the passage of cooling air into the motor and air exhaust vents for passage of warmed exhaust air from the motor, the air inlet and air exhaust vents opening at the external surface, the air exhaust vents being spaced from the air inlet vents; and a boot including a body having a circular cross section and an interior surface that corresponds generally to a shape of the external surface of the motor and at least a portion of the interior surface resiliently coupled to the external surface of the motor and the body being disposed between the air inlet vents and the air exhaust vents, the boot having a radial flange mounted in a seat formed by the interior surface of one of the first and second housing members, the flange having a circumferential outer edge that abuts against the seat so that the boot is disposed between the seat and the motor in order to provide vibration dampening for the motor and to form a barrier between the air inlet and air exhaust vents to substantially prevent exhaust air from the air exhaust vents from entering the air inlet vents.
