PCT No. PCT/DE86/00491 Sec. 371 Date Aug. 4, 1987 Sec. 102(e) Date Aug. 4, 1987 PCT Filed Dec. 2, 1986 PCT Pub. No. WO87/03663 PCT Pub. Date Jun. 18, 1987.A two-part, low compression height, open-ended hollow skirt-type piston for internal combustion engines has a piston pin creating an articulated connection of the separate skirt and head parts. Guide portions (5) protruding axially in the direction of the piston axis provide lateral guidance and support of the piston head (1) in the piston-pin-axis direction. Each of the guide portions forms a gap with the nearby gudgeon pin boss (3). The gaps receive opposite parallel flat surfaces (4) of the skirt (2). The overhanging guide portions (5) have partly circular recesses permitting assembly of head and skirt with the gudgeon pin.
