Abstract
A one-piece piston having an investment or other permanent or non-permanent mold/die precision cast piston crown, rod flange and piston skirt. The piston crown has a relative constant thickness, a flange requiring minimal machining and a skirt providing for a wall with a support against the angular shifting of the piston. This improves the distribution of heat within such crown and the angular stability of the piston wall at the piston rod connection.
