ABSTRACT:
An improved pneumatic operating mechanism construction is provided including the usual stationary operating cylinder with a movable reciprocally-operable driving piston member movable therewithin, and having an extremely-fast pneumatic valve-device cooperable with a movable valve-sealing member attached to, and carried by, the driving side of the movable driving piston. Additionally, a valve-piston bore is provided internally within the stationary valve-housing member, within which reciprocally pneumatically operates the movable valve piston.
