Patent number: 8770341Abstract: A muffler for a feed air system of a compressor assembly. The muffler can be a product of a blow molding process and used in a method of sound control for a compressor assembly. A method of controlling sound in a compressor assembly can have the step of providing a feed air and the step of providing the muffler an outlet in communication with an inlet of a pump assembly which can compress the feed air fed through the muffler and into the pump assembly. Sound control for a compressor assembly is also accomplished by adapting a feed air system to have sound control of a feed air path by dampening the sound emitted from a pump system through the feed air path.Type: GrantFiled: September 11, 2012Date of Patent: July 8, 2014Assignee: Black & Decker Inc.Inventors: Mark W.

Patent number: 8057196Abstract: A compressor assembly includes a compressor coupled to a motor via a belt drive. The belt drive provides a speed reduction between the motor and compressor and causes the compressor shaft to rotate in the direction opposite that of the motor shaft. The relative values of the mass moments of inertia about the axes of rotation of the rotating motor and compressor shafts are engineered to be inversely proportional to the relative shaft speeds, allowing the mass moments of inertia to be balanced to at least substantially eliminate torsional vibration.Type: GrantFiled: May 21, 2003Date of Patent: November 15, 2011Assignee: Black & Decker Inc.Inventor: Mark W.

Patent number: 7765917Abstract: An air compressor that employs splash lubrication to lubricate and cool a piston kit that includes a cylinder and a piston reciprocating in the cylinder. In one form, cooling channels can be coupled to or formed on the cylinder to direct the lubricant that is splashed onto the cylinder to drain in a desired manner, such as helically around the exterior of the cylinder, to more effectively cool the piston kit. In another form, the cylinder can include an annular flange that can be bigger in diameter than a remainder of the cylinder. The annular flange can be received into a counterbore in a cylinder block. A cylinder head, which can be fastened to the cylinder block, can apply a clamping force to the annular flange to clamp or fix the cylinder to cylinder.Type: GrantFiled: December 20, 2007Date of Patent: August 3, 2010Assignee: Black & Decker Inc.Inventors: John W.
