Abstract
A pneumatic tool sound dampening system includes a housing that has a first end, a second end and a perimeter wall extending between the first and second ends. The first and second ends are open. The housing includes a first section including the first end and a second section including the second end. The first end is fluidly coupled to an exhaust port of the pneumatic drive apparatus. An interior of the first section forms an expanding cone extending toward the second section. A funnel is positioned within the second section. The funnel forms a decreasing cone extending away from the first section and toward the second end. The funnel is fluidly coupled to the second end.
Claims7
A sound dampener assembly comprising:
- a pneumatic drive apparatus;
- a housing having a first end, a second end and a perimeter wall extending between said first and second ends, said first and second ends being open, said housing including a first section including said first end and a second section including said second end, said first end being fluidly couplable to an exhaust port of the pneumatic drive apparatus, an interior of said first section forming an expanding cone extending toward said second section;
- and
- a funnel being positioned within said second section, said funnel forming a decreasing cone extending away from said first section and toward said second end, said funnel being fluidly coupled to said second end, said funnel having a proximate end with respect to said second end, said proximate end being open.
A sound dampener assembly comprising:
- a pneumatic drive apparatus;
- a housing having a first end, a second end and a perimeter wall extending between said first and second ends, said first and second ends being open, said housing including a first section including said first end and a second section including said second end, said first end being fluidly couplable to an exhaust port of the pneumatic drive apparatus, an interior of said first section forming an expanding cone extending toward said second section;
- a funnel being positioned within said second section, said funnel forming a decreasing cone extending away from said first section and toward said second end, said funnel having a proximate end with respect to said second end, said proximate end of said funnel with respect to said second end being open;
- a tube being attached to said funnel and extending through said proximate end of said funnel with respect to said second end, said tube extending through said second end, said tube being releasably secured to said housing such that said tube and said funnel are movable relative to said housing;
- and
- an exhaust conduit being fluidly coupled to said second section, said housing having a longitudinal axis extending through said first and second ends, said exhaust conduit forming an angle with respect to said longitudinal axis between 45° and 135°.
