Balancing shafts for I.C. engine consist of one carrying driven pinion and transfer pinion, meshing with second shaft pinion, comprising hydraulic filtering device for out of cycling between driven pinion and shaft

摘要

There are two balancing shafts the first of which carries a driven pinion meshing with the crankshaft crown wheel and a transfer pinion (18) meshing with a pinion on the second balancing shaft. A hydraulic filtering device for the out of cycling between the driven pinion and the associated balancing shaft comprises a semi-cylindrical chamber and a radial partition (44) which divides the chamber into two sub-chambers (46a,46b) which are filled with liquid.
