Abstract
The application discloses a new silencer for internal combustion engines. This silencer comprises an internal resilient tube capable to vibrate longitudinally and permeable to the exhaust gas and an external sheath. An end piece closes the internal tube. Spacers are secured to the internal tube and another end piece provided with apertures is secured to the end of the external sheath. The exhaust gases exit from the internal tube through the space comprised between the spacers and the external sheath towards said apertures in the other end piece.
Claims6
A silencer for an internal combustion engine, comprising:
- a supple resilient internal tube, adapted to vibrate longitudinally under the influence of the exhaust gas and permeable to said gas, receiving the exhaust gas from said engine;
- an elastic external sheath which is substantially not supple and not adapted to vibrate longitudinally and substantially not permeable to the gas, said sheath being substantially coaxial with the internal tube;
- an end piece closing the internal tube at the end opposite to the inlet of the exhaust gas therein;
- washers or spacers slideably secured to the internal tube at irregular intervals and permitting the gas to pass in the annular space comprised between the washers or spacers and the external sheath;
- an end piece secured to the end of the external sheath opposite to the inlet of the gas and provided with apertures for the output of the exhaust gas;
- and
- an expansion chamber between the end piece closing the internal tube and the end piece secured to the end of the external sheath.
