  • Pneumatic or pressurized fluid tool having a control device
    Patent number: 5913370
    Abstract: Pneumatic or pressurized fluid tool, such as a screwdriver, having a control device. The control device includes a pivotally mounted trigger which causes rotation of the motor in a first rotational direction when pivoted in a first direction and which causes rotation of the motor in an opposite rotational direction when pivoted in a second direction opposite to the first direction. The trigger is connected to a piston which is movable in a cylinder. The piston is connected by a rod to a valve and includes a cam. The cam of the piston, cooperating with a plunger, operates a selector so that when the trigger is pivoted in the first direction, compressed air or pressurized fluid is admitted to rotate the motor in the first direction.
