Abstract
A pressure device maintains the raceways (48, 160 to 165) of the main moving components (3, 5, 7 and 40) of a variable compression ratio engine permanently in contact with one another and with the faces on which they rest in a cylinder case. The inventive device includes pressure elements which are solidly connected to the cylinder case (100) and which exert a pressure force on a control rack (7) having a toothed segment (75) formed by teeth (74). The pressure force is applied against a support surface (78) provided on the lower part of the rack (7).
