ABSTRACT:
A simple and rugged three-way valve is disclosed which may be used as a trigger-operated control valve for portable pneumatic tools. The valve utilizes a novel valve member slidably disposed in a valve chamber for reciprocal movement between two valve seats and is arranged so that it cannot obstruct a side port that is located between the valve seats.
