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