ABSTRACT:
A piston assembly for use in a piston cylinder of an engine is disclosed. The piston assembly includes a piston rod which connects the piston assembly to a crankshaft. The piston rod has a pin receiving opening at an upper end. A piston head having a transverse bore is connected to the piston rod. A piston pin is disposed through the pin receiving opening of the piston rod and the transverse bore of the piston head. The piston pin connects the piston head to the piston rod and has an axial bore. A piston skirt is connected to the piston head. The piston skirt has a transverse bore and an oil reservoir formed in the upper surface. At least one piston skirt pin is disposed through the piston pin axial bore and the transverse bore of the piston skirt to connect the piston skirt to the piston pin. This connects the piston skirt to the piston head. A fastening device secures the piston skirt pin in position within the piston skirt and the piston pin. The distance between the top surface of the piston and the center line of the piston pin may be made shorter than the equivalent distance in a conventional piston head-piston skirt-piston pin assembly. Additionally, the weight of the piston assembly is less than the weight of a conventional piston head-piston skirt-piston pin assembly made from identical materials.
