Abstract
The induction exhaust has an exhaust manifold 16 and a muffler 22. In the instant invention, warm ambient air is drawn into the muffler 22. Heat from this external source is conducted through the finned manifold 16 to melt ice that can form inside the manifold 16 during the exhaust cycle. The exhaust manifold 16 bolts to the side of the air motor air valve 14 and serves to direct, muffle and diffuse the air motor exhaust using a deflection plate, a diffraction plate and an expansion chamber is provided in the manifold to direct the exhaust out of the air valve and down the center of the muffler 22.
Claims7
An exhaust for use with a reciprocating air motor having an air valve, said exhaust comprising:
- a finned exhaust manifold;
- a muffler;
- air passages for drawing warm ambient air into said muffler so that heat from said warm ambient air is conducted through said finned manifold to melt ice that can form inside the manifold during the exhaust cycle.
