Piston with active structure

摘要

The present invention relates to a piston and a piston—connecting rod assembly for internal combustion engines or compressors, featuring a pinless connecting rod assembly having a joint claw, whereas the joint claw is formed to partly encompass an upper joining end of a connecting rod, whereas the joint claw is formed as a part of an inner section of the piston, and whereas the inner section is radially encircled by a cylindrical piston skirt. According to the invention at least one bar element is arranged extending between the inner section and the piston skirt, whereas the bar element divides a first open section from at least one second open section being arranged between the inner section and the piston skirt.

主权项

1. A piston for use in a pinless connecting rod assembly in internal combustion engines or compressors, comprising:
a piston body having an inner section defined therein; a cylindrical piston skirt integrally formed with and extending from said piston body and radially encircling said inner section; a joint claw integrally formed in said inner section of said piston body and configured to at least partially encompass a complimentary upper joining end of a connecting rod; at least one bar element extending between said inner section and said piston skirt, said at least one bar element separating a first open section from at least one second open section, said first and second open sections being defined between said inner section and said piston skirt.
