Abstract
Provided is a high pressure piston crown capable of withstanding a higher pressure than the existing piston crown by changing an internal structure of the piston crown reciprocating in a cylinder while being coupled with an upper portion of a piston skirt. The high pressure piston crown includes: a rib partincluding a plurality of main ribsthat are radially disposed, have one side connected to a central portion C of the high pressure piston crown, and have a cross sectional area wider toward an outside of the high pressure piston crown; an oil galleryformed by the rib partand making cooling oil introduced from the piston skirt flow therein; and a lower plateformed under the central portion C and connected to the rib partto have an inside thereof connected to the oil gallery
