REDUCED NOISE RECIPROCATING PNEUMATIC MOTOR

摘要

A reduced-noise pneumatic motor has a housing with a cap disposed at a firstend, the cap havingan air inlet; a base disposed at a second end, the base having an air outlethole formed therein andconfigured to at least partially receive a noise damping system, and a pistonpump extendingtherethrough; and bolts extending from the cap to the base to secure the capand the base to thehousing. A pneumatic piston is disposed within the housing, and includes ashuttle valve situatedwithin a central bore of the pneumatic piston. A piston rod has a first endextending into thepiston pump and a second end secured to a spring which biases the piston rodagainst thepneumatic piston.
