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.

Description

The air operated machine exhaust gear of freezing noise reduction

Technical field

It is the preceence of 60/820,405 U. S. application that the application requires in the sequence number that on July 26th, 2006 submitted to.

Background technology

Although reciprocating type air operated machine is very suitable for operating reciprocating piston pump, they also suffer exhaust roar and have rapid expansion owing to exhaust to make ice be deposited in tendency in choker relief valve and/or the exhaust passage frequently.US Patent the 4th, 921, No. 408 a kind of trials that the improvement operation is carried out that come to this, and its content mode is by reference incorporated into.

Summary of the invention

Air-breathing exhaust gear has exhaust manifold and silencer.In the present invention, warm ambient air is inhaled in the silencer.Heat from this external source is conducted through finned menifold to melt the ice that can form in menifold inside during discharge cycle.

Exhaust manifold is directed to evacuating air stream in the silencer, makes it produce thin high-speed air flow, produces meiobar owing to Bernoulli effect on the both sides of described air-flow.This meiobar produces difference of pressure, and warm extraneous air is drawn in the exhaust system.The extraneous air that is sucked is many more, then freeze be reduced also will be many more.This need make the exhaust gas pressure in downstream minimize.

Yet, the exhaust gas pressure in downstream is minimized can cause higher noise level.In order to reduce noise, after the outlet of silencer, increase reverberation chamber, allow sound wave along with the time disperses, counter pressure is minimized.Reciprocating type air operated machine has short (15 to 50 milliseconds) noise impact ripple, and reverberation chamber has reduced the peak level of noise and increased the time length of noise.Described reverberation chamber also has the minimized capacity function of the exhaust gas pressure that makes the downstream (capacitancefunction).

The exhaust manifold bolted connection is to the side of air operated machine choker relief valve, and use that several parts come to air operated machine that exhaust is guided, noise reduction and dispersion.Deflector disperses this initial exhaust blast when initial exhaust blast is left choker relief valve and entered exhaust manifold.This deflector is deflection opening noise and the shock wave of tight gathering (tightly focused) is slowed down and scatter partly, has reduced noise and exhaust velocity thus.Diffractive plate in the exhaust manifold (diffraction plate) makes exhaust blast diffraction and dispersion by many apertures rather than a bigger cross-sectional plane, thereby reduces noise and exhaust velocity again.Expansion chamber is arranged in the menifold exhaust is drawn and is directed to the center of silencer downwards from choker relief valve.The cross-sectional plane of silencer also is divided into expansion chamber and nozzle, and wherein this expansion chamber allows exhaust blast to expand before leaving menifold by diffractive plate and nozzle and dissipate.

From the description of carrying out below in conjunction with accompanying drawing, these and other purposes of the present invention and advantage will manifest more fully.Wherein, in whole views, similarly Reference numeral refers to same or analogous part.

Description of drawings

Fig. 1 shows the cross-sectional plane of air operated machine, specifically is the cross-sectional plane of its exhaust system.

The specific embodiment

Air operated machine 10 of the present invention has piston 12 and choker relief valve 14.Air-breathing exhaust gear has exhaust manifold 16 and silencer 22.In the present invention, warm ambient air is inhaled in the silencer 22.Heat from this external source is conducted through finned menifold 16 to melt the ice that can form in menifold 16 inside during discharge cycle.

Exhaust manifold 16 is directed to evacuating air stream in the silencer 22, makes it produce thin high-speed air flow, produces meiobar owing to Bernoulli effect on the both sides of described air-flow.This meiobar produces warm extraneous air is drawn into difference of pressure in the exhaust system.The extraneous air that is sucked is many more, freeze be reduced also will be many more.This need make the exhaust gas pressure in downstream minimize.

Yet, the exhaust gas pressure in downstream is minimized can cause higher noise level.In order to reduce noise, after the outlet of silencer 22, increase reverberation chamber 26, allow sound wave along with the time disperses, make the counter pressure minimum simultaneously.Reciprocating type air operated machine has short (15 to 50 milliseconds) noise impact ripple, and reverberation chamber has reduced the peak level of noise and increased the time length of noise.Described reverberation chamber also has the minimized capacity function of the exhaust gas pressure that makes the downstream.

Exhaust manifold 16 bolted connections are to the side of air operated machine choker relief valve 14, and use that several parts come to air operated machine that exhaust is guided, noise reduction and dispersion.Deflector disperses this initial exhaust blast when initial exhaust blast is left choker relief valve and entered exhaust manifold.This deflector is deflection opening noise and the shock wave of tight gathering is slowed down and scatter partly, reduces noise and exhaust velocity thus.Diffractive plate in the exhaust manifold makes exhaust blast diffraction and dispersion by many apertures rather than a bigger cross-sectional plane, thereby reduces noise and exhaust velocity again.Expansion chamber is arranged in the menifold exhaust is drawn and is directed to the center of silencer downwards from choker relief valve.The cross-sectional plane of silencer also is divided into expansion chamber and nozzle, and wherein this expansion chamber allows exhaust blast to expand before leaving menifold by diffractive plate and nozzle and dissipate.

Be expected under the situation about not departing from, can make variations and modifications exhaust system by the appended the spirit and scope of the present invention that claim limited.
