    Abstract: A fluid operated hydraulic pump of the type using air pressure to produce high pressure hydraulic fluid wherein an air pressure driven motor and a hydraulic pump are positioned in adjacent axially aligned relationship and the air motor includes a reciprocating piston which drives the hydraulic pump. The air motor includes an exhaust passage having an expansion chamber therein for receiving exhaust air flow and including a plurality of baffles therein, the expansion chamber and the baffles functioning in combination to reduce the noise generated by the air motor without the use of other muffling material thereby avoiding undue back pressure in the air motor and increasing the speed and efficiency and operation of the air motor and the pump.
