In an improved air inlet valve assembly, a flow of air along a first or second flow path may be controlled by a position of air inlet guide surfaces of a rotatable valve relative to air inlet guide slots of a fixed valve sleeve. Air flowing along the first flow path may rotate a motor in a first direction to operate the tool in a forward mode. Air flowing along the second flow path may rotate the motor in the second direction to operate the tool in a reverse mode. In the forward mode, as air flows along the first flow path, air may be discharged along a primary discharge path, with a portion of the second flow path providing a secondary discharge path. In the reverse mode, as air flows along the second flow path, air may be discharged along the primary discharge path, with a portion of the first flow path providing the secondary discharge path.

Bidirectional air inlet valve assembly

In a pneumatic-powered tool, a flow of air along a first or second flow path may be controlled by a position of air inlet guide surfaces of a rotatable valve relative to air inlet guide slots of a fixed valve sleeve. Air flowing along the first flow path may rotate a motor in a first direction to operate the tool in a forward mode. Air flowing along the second flow path may rotate the motor in the second direction to operate the tool in a reverse mode. In the forward mode, as air flows along the first flow path, air may be discharged along a primary discharge path, with a portion of the second flow path providing a secondary discharge path. In the reverse mode, as air flows along the second flow path, air may be discharged along the primary discharge path, with a portion of the first flow path providing the secondary discharge path.

Forward-reverse valve and pneumatic tool having same

A power tool (e.g., a pneumatic tool) includes a tool housing, a motor disposed in the tool housing, and a switch coupled to the tool housing and configured to control operation of the motor. A light unit includes a light unit housing removably coupleable to the tool housing. The light unit includes a light disposed in the light unit housing, a controller, and a sensor. The sensor is configured to sense actuation of the switch, and the controller is configured to cause the light to turn on when the sensor senses that the switch is actuated.
