Abstract

A compressed gas muffler that accommodates multiple sources and removes back-pressure to the source has a housing with a top, a bottom, and four sides. An inlet has a lip and an open center. The lip extends from the top of the housing. The open center extends from the lip through the top of the housing. A plurality of sound-absorbent baffles are disposed inside the housing. Baffles lay parallel to each other and project from opposite sides of the housing. An open space of uniform size is maintained between the baffles. An outlet extends along the width of one side of the housing. The outlet is located on one side and near the bottom of the housing. A tube fits around the lip of the inlet. The tube is used to vent compressed gas from its source to the muffler. Compressed gas flows out of the tube, through the inlet, and into the housing. Compressed gas continues to flow through the open space between the baffles. As the air flows through the open space, noise is absorbed by the baffles. Compressed gas exits the housing through the outlet. The outlet is significantly larger than the inlet, eliminating both back pressure and exit noise from the gas.
