ABSTRACT:
Pulsation dampener apparatus includes a cylindrical housing having three baffles dividing the interior of the housing into four chambers. A conduit within the apparatus connects the top and bottom chambers, and a second conduit connects the second, third, and fourth chambers. Pressurized air for operating a pneumatic tool, such as a drill or the like, is connected to the top chamber from a main air line or manifold. The pressurized air flows from the bottom chamber directly to the tool. Back pressure pulsations caused by the tool, are dampened within the second and third chambers of the cylinder so that the pulsations are not fed back into the main air line or manifold, where they may cause problems with other pneumatic tools connected to the main air line or manifold.
