Piston for internal combustion engine has cooling channel enclosing access channel narrowing in cross-section towards piston floor, inclined to annular field, leading directly or indirectly to annular support
摘要
#CMT# #/CMT# The piston (1) consists of a cast piston of light metal with a trough (3) in a piston floor, an annular support (5) and at least one peripheral cooling channel (6) formed by an inserted core integrated at a distance from the annular support. The cooling channel encloses an access channel (7a) narrowing in cross-section towards the floor of the piston and inclined with respect to an annular field that directly or indirectly leads to the annular support. #CMT#USE : #/CMT# For an internal combustion engine. #CMT#ADVANTAGE : #/CMT# Improved cooling of the thermally highly loaded zones and paths of the piston. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic sectional representation of a piston 1 : piston 3 : trough 5 : annular support 6 : cooling channel 7a : access channel.
