<p>Oil Cooled Piston Substantial heat is generated at the crown portion of a piston. Cooling fluid has been directed to cavities in the underside of the crown. However, at critical points of the piston cycle, the fluid drains from the cavities due to the forces of gravity. An oil cooled piston is provided which includes a fluid trap adjacent the crown. Some of the cooling fluid is trapped as it drains and is retained to enhance cooling of the crown. The fluid trap includes a slot permitting a jet spray of lubricating oil to be directed past the trap to the cavities adjacent the underside of the crown.</p> |
