  • Reciprocating piston engine construction, particularly multi-part cylinder and crankshaft connection arrangement
    Patent number: 4013058
    Abstract: To connect two machine elements which are dynamically loaded by means of tension bolts, the bolts are carried through bores in the machine elements which are somewhat wider than the diameter of the bolts to form a cylindrical chamber, leaving a cylindrical gap surrounding the bolt; the chamber is entirely filled with a damping substance, such as a foamed material, or lubricating oil, particularly pressurized lubricating oil or the like. Preferably, the gap is about 2 to 8 percent of the diameter of the tension bolt, has a length at least three times the diameter of the tension bolt, and is located approximately centered between the points of force application on the tension bolt, to dampen transfer of vibrations, but permit slow bending, below the yield point of the bolt, within the chamber.
