    摘要： 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.

    摘要： An improved air reversing valve, as for use with a pneumatic scaler, chisel or the like, comprising throttling means between the two sides of the valve disc whereby the tool's performance characteristics are generally improved. Additionally, the valve is made multi-element whereby its manufacture is simplified, as by powdered metal casting internal passageways in facing surfaces of adjacent parts, rather than cross drilling or the like.
