摘要:
The invention relates to a piston (1) for an internal combustion engine, configured as a gallery-cooled piston of two-piece construction which comprises a main body (2) and a ring element (3). The ring element (2) which has a ring zone (18) and a fire land (17) encloses a cooling gallery (15) on the outside, which cooling gallery (15) is delimited on the inside by an intermediate wall (16) which separates the cooling gallery (15) from a combustion-chamber recess (12) which is made in a piston head (10) of the main body (2). The main body (2) and the ring element (3) together form two circumferential dividing planes (4a, 5a) which are offset with respect to one another, to which end in each case two interacting joining webs (6a, 6b; 7a, 7b) of the ring element (3) and of the main body (2) are connected with a material-to-material bond.
