ABSTRACT:
An air operating reciprocating motor which is used to drive reciprocating piston pumps or other such devices has located in the exhaust passage thereof a liner made of a flexible elastomeric material. The inside surface of the liner which routes the exhaust area is generally smooth and the outside surface of the liner is spaced from the surface of the passage in which it is located by a number of spacer elements such as rounded knobs. The material between the spacing elements is then allowed to flex when the exhausted relatively high pressure air passes through, thus continually flexing the liner with every cycle of the motor and preventing the buildup of ice in the exhaust passage.
