Abstract
A muffler is described which is traversed by a fluid. Housing (1) contains sound-absorbent built-in components. The sound-absorbent components contain corrugated sheets (11, 12) instead of fibrous materials. (FIG. 3).
Claims20
Muffler for damping vibrations in a fluid flowing therethrough, comprising:
- a housing;
- and
- a plurality of sound absorbent baffles arranged in said housing in a path of fluid flow therein;
- each of said sound absorbent baffles comprising at least one corrugated sheet having corrugations which comprise longitudinally spaced alternating ridges and valleys each of said ridges and valleys having a longitudinal cross-sectional profile which is substantially rectangular.

Method of damping vibrations having at least one preselected frequency in a fluid flow generated by a machine, said method comprising the step of
- passing said fluid flow through a muffler having a plurality of vibration absorbent elements arranged in a muffler housing, said vibration absorbent elements comprising corrugated sheets having corrugations which comprise longitudinally spaced alternating ridges and valleys, each of said ridges and valleys having a longitudinal cross-section profile which is substantially rectangular.
A muffler for damping vibrations in a fluid flowing therethrough, comprising:
- a housing defining a fluid flow path;
- a plurality of sound absorbent baffles arranged in said fluid flow path in said housing;
- each of said sound absorbent baffles comprising at least one sheet of corrugated material having a plurality of adjacent parallel extending corrugated strips, each of said corrugated strips having a succession of alternating transverse ridges and valleys along a length thereof;
- ridges and valleys of adjacent corrugated strips being in alignment with each other, with sufficient difference of alignment to define gaps which provide an acoustic connection between adjacent peaks and valleys.
