Abstract
A defined exhuast restriction in the form of an orifice or variable valve is provided to back-pressure the pulsating exhaust of an air motor or the like to reduce the formation of ice in the exhaust system.
Claims6
An air motor including:
- a working air chamber adjacent a reciprocating piston or diaphragm or the like for continuously extracting work from an air supply at a rate sufficient to form ice in expanded air exhausting said working air chamber, said working air chamber including an inlet for receiving compressed air and an exhaust port including a passage to exhaust said air supply;
- and
- a means for prevention of exhaust flow icing comprising:
- restriction means in said passage to exhaust for accurately controlling the discharge pressure and air flow from said working air chamber for controlling the air temperature exiting the exhaust of said working air chamber.
