  • Control valves
    Patent number: 4098295
    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.
    Type: Grant

  • Pneumatic piston apparatus
    Patent number: 4098171
    Abstract: An improved pneumatic piston apparatus is provided wherein a movable poppet valve member employs at least one composite member exposed to air pressure which varies dynamically during the operation of the apparatus. Delamination of the composite member and resultant malfunction of the poppet valve are avoided by a novel construction in accordance with the principles of the present invention, which excludes the dynamically varying air pressure from access to the interface between the layers of the separate materials comprising the composite member. The effect achieved by the novel construction is further enhanced by the manner in which the composite member is retained on the poppet valve member. Unwanted movement of the piston conjointly with the motion of the poppet valve member is precluded in the invention by providing an air space therebetween.

  • Control valves
    Patent number: 4051862
    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.
