Heat engine e.g. diesel engine, has continuous and intermittent rotation rotors with lubricators supplied by oil circuit to deliver lubrication fluid on surfaces of working chambers in front of sealing segments associated to rotors

摘要

The engine has outer and inner sealing segments (11, 12) respectively formed on an outer cylindrical surface and on an axial bore`s surface of a continuous rotation rotor (3). Another sealing segment is formed on a vane of an intermittent rotation rotor. The rotors have lubricators (22) supplied by a pressurized oil circuit to deliver a lubrication fluid on surfaces of working chambers in front of the segments to lubricate the segments.
