Abstract:
A pneumatic power tool in which a throttle valve controls the rate at which the pressurized air within the tool may be released. By doing so, the rotatable motor may not only be quickly accelerated through the use of the pressurized air but, furthermore, may be quickly decelerated by using the same pressurized air. The subject invention is also directed to a method for controlling the speed of a rotating pneumatic power tool by blocking the flow of the exhaust air.
