  • Reduced noise reciprocating pneumatic motor
    Patent number: 10598196
    Abstract: A reduced-noise pneumatic motor has a housing with a cap disposed at a first end, the cap having an air inlet; a base disposed at a second end, the base having an air outlet hole formed therein and configured to at least partially receive a noise damping system, and a piston pump extending therethrough; and bolts extending from the cap to the base to secure the cap and the base to the housing. A pneumatic piston is disposed within the housing, and includes a shuttle valve situated within a central bore of the pneumatic piston. A piston rod has a first end extending into the piston pump and a second end secured to a spring which biases the piston rod against the pneumatic piston.
