Description

200830674 IX. INSTRUCTIONS OF THE INVENTION [Technical Fields of the Invention] This application claims the benefit of No. 60/820,405, which is incorporated herein by reference. This type of valve and/or _ 4, 921, 408 is incorporated herein by reference. SUMMARY OF THE INVENTION The inductive exhaust device has a light medium in which the heat absorbed by the surrounding air is conducted through the fin ring to guide the exhaust gas to a high speed during the inner side of the manifold. Thin airflow, and due to the vertical low pressure area. This low pressure zone enters the differential pressure of the exhaust system. Inhalation Less frosting. This requires a downstream row, however, to make the downstream exhaust pressure level. In order to reduce noise, the US patent application was filed on the 26th of the month. Extremely suitable for running reciprocating piston pumps Rapid expansion suffers from exhaust noise and a tendency in the L-channel. The U.S. Patent Tests ' improve operation and its content is an exhaust manifold and a silencer. The silencer is issued here. A manifold from this external source is melted to circulate the exhaust. Airflow enters the muffler so that its built-in effect builds up on the sides of the airflow to create a warmer external air that draws more outside air, minimizing more depressurization pressure. Minimizing the force can result in higher noise. After the muffler exits, add a reverberation chamber -5 - 200830674 and allow the sound wave to disperse over time while minimizing back pressure. The reciprocating air motor has a short (15-5 0 millisecond) explosion air noise, and the reverberation chamber reduces the peak level and increases the period of the noise. The chamber also has a capacitive function that minimizes downstream exhaust pressure. The exhaust manifold is bolted to the side of the air motor valve and has the function of guiding, silencing, and diffusing the air motor exhaust using a plurality of components. A deflection plate disperses the initial exhaust gas explosion when the exhaust gas explosion leaves the gas valve and enters the exhaust manifold. The deflector partially deflects the port noise and slows and dissipates the tightly concentrated explosion of air, thereby reducing noise and exhaust velocity. The diverging plate in the exhaust manifold circulates through a number of small holes and disperses the exhaust gas stream rather than a larger cross section, and again reduces noise and exhaust velocity. An expansion chamber is disposed in the manifold to direct the exhaust gas from the gas valve and down to the center of the muffler. The muffler cross section is also split into an expansion chamber and a nozzle having the expansion chamber to allow the exhaust gas to expand and dissipate before exiting the manifold through the diffraction plate and nozzle. These and other objects and advantages of the present invention will be more fully apparent from the description of the appended claims. [Embodiment] The air motor 10 of the present invention has a piston 12 and a gas valve 14. The induction exhaust has an exhaust manifold 16 and a silencer 22. In the present invention, warm ambient air is drawn into the muffler 22. Heat from this external source -6-200830674 is conducted through the finned manifold 16 to dissolve ice that may form inside the manifold 16 during the exhaust cycle. The exhaust manifold 16 directs the flow of exhaust gas into the muffler 22 such that it establishes a high velocity thin gas stream and creates a low pressure region on both sides of the gas stream due to the Null effect. This low pressure region establishes a pressure differential that draws the warm outside air into the exhaust system. Inhaling more outside air will reduce frosting more. This requires minimizing downstream exhaust pressure. However, minimizing downstream exhaust pressure can result in higher noise levels. To reduce noise, a reverberation chamber 26 is added after the exit of the muffler 22, and the acoustic waves are allowed to disperse over time while minimizing back pressure. The reciprocating air motor has a short (15-50 millisecond) explosion air noise, and the reverberation chamber reduces the peak level and increases the period of the noise. The chamber also has a capacitive function that minimizes downstream exhaust pressure. The exhaust manifold 16 is bolted to the side of the air motor valve 14 and has the effect of using several components to direct, silence, and diffuse the air motor. A deflection plate disperses the initial exhaust gas explosion when the exhaust gas explosion leaves the gas valve and enters the exhaust manifold. The deflection plate locally deflects the port noise and slows down and dissipates the tightly concentrated explosion gas stream, thereby reducing noise and exhaust velocity. The diverging plate in the exhaust manifold circulates through a number of small holes and disperses the exhaust gas stream rather than a larger cross section, and again reduces noise and exhaust velocity. An expansion chamber is disposed in the manifold to direct the exhaust gas from the gas valve and down to the center of the muffler. The muffler cross section is also split into an expansion chamber and a nozzle having the expansion chamber -7-200830674, allowing the exhaust gas to expand and dissipate before exiting the manifold through the divergence plate and nozzle. It is intended that various modifications and changes can be made to the exhaust system without departing from the spirit and scope of the invention, as defined by the scope of the following claims.
