Abstract
A discharge muffler construction having a casing which defines a noise attenuation cavity and which is provided with an inlet and outlet located at substantially opposite portions thereof and communicating with the cavity, a baffle plate in the cavity intermediate the inlet and outlet and partitioning the same into at least two chambers, the baffle plate having an arcuate surface concave to the inlet, an aperture through the baffle plate, and a tubular conduit mounted through the aperture and placing the chambers in fluid communication.
Claims23
A gas compressor discharge muffler comprising casing means defining noise attenuation cavity means, inlet means and outlet means located at substantially opposite portions of said casing means and communicating with said cavity means, each of said inlet and outlet means having a flow axis, baffle plate means having an inlet side and an outlet side and positioned in said cavity means intermediate said inlet and outlet means and partitioning said cavity means into inlet and outlet chamber means, said inlet side of said plate means having concave arcuate surface means oriented generally normally to said flow axis of said inlet means and formed substantially on a radius of from about 1.0 to about 4.0 inches, and conduit means formed through said plate means and placing said inlet and outlet chamber means in fluid communication with each other.
A gas compressor discharge muffler comprising casing means defining noise attenuation cavity means, inlet aperture means and outlet aperture means through said casing means at spaced locations thereon and communicating with said cavity means, each of said aperture means having a flow axis, baffle plate means mounted in said cavity means intermediate said inlet and outlet means and having an inlet side and an outlet side and partitioning said cavity means into an inlet chamber and an outlet chamber, said inlet side of said plate means having an arcuate surface generally facing toward said inlet aperture means and formed on a radius of from about 1.0 to about 4.0 inches, and tubular conduit means mounted through said plate means and placing said inlet and outlet chambers in fluid communication with each other.
A gas compressor discharge muffler comprising casing means defining noise attenuation cavity means, said casing means being comprised of two generally cup-shaped section each of which has a major wall means and side wall means and end wall means integral with peripheral portions of said major wall means and extending generally outwardly therefrom, portions of the side wall means and end wall means of one section being tightly nested and secured within a portion of the side wall means and end wall means of the other section, and inlet aperture means and outlet aperture means through said casing means at spaced locations thereon and communicating with said cavity means, baffle plate means mounted in said cavity means intermediate said inlet and outlet means and having an inlet side and an outlet side and partitioning said cavity means into an inlet chamber and outlet chamber, said inlet side of said plate means having concave arcuate surface means generally facing toward said inlet aperture means, substantially on a radius of from about 1.0 to about 4.0 inches and tubular conduit means mounted through said plate means and placing said inlet and outlet chambers in fluid communication with each other, said conduit means having inlet port means laterally offset from said inlet aperture means, and having outlet port means laterally offset from said outlet aperture means.
