摘要： The present invention relates to a piston (10) and a piston - connecting rod assembly (1) for internal combustion engines or compressors, featuring a pinless connecting rod assembly having a joint claw (11), the joint claw (11) is formed to partly encompass an upper joining end (12) of a connecting rod (13), whereas the joint claw (11) is formed as a part of an inner section (14) of the piston (10), and whereas the inner section (14) is radially encircled by a cylindrical piston (15). According to the invention at least one bar element (16) is arranged extending between the inner section (14) and the piston skirt (15), whereas the bar element (16) divides a first open section (17) from at least one second open section (18) being arranged between the inner section (14) and the piston skirt (15).
