An improved axial-piston energy converting device is provided by utilizing a thin ceramic wear plate insert, having a typical thickness of only about .005 to .040 inches in thickness, as a cam surface secured by atmospheric pressure to an underlying support surface of a steel cam plate support structure. Attachment of the wear plate to the cam plate supporting surface is accomplished by polishing both a supporting surface of the cam plate, and a mating surface of the wear plate to a very smooth finish, and wiping a thin film of a fluid such as oil onto one of the polished surfaces prior to placing the wear plate onto the supporting surface. The highly polished surface, together with the light film of oil, results in a joint that is essentially air tight. Atmospheric pressure acting on the cam surface of the wear plate serves to hold the wear plate tightly in place on the support surface in the same manner that a pair of Johansson blocks are held together if their highly polished surfaces are mated.

L'invention concerne un dispositif perfectionné de transformation d'énergie, à pistons axiaux, dans lequel on utilise une fine plaque d'usure rapportée en céramique, d'une épaisseur type d'environ 0,005 à 0,040 pouces seulement, comme surface de came, assujettie par la pression atmosphérique à une surface de support sous-jacente d'une structure support de came de commande en acier. On réalise la fixation de la plaque d'usure à la came de commande en polissant à la fois une surface de support de la came de commande, et une surface correspondante de la plaque d'usure jusqu'à l'obtention d'un fini très lisse, et en appliquant une pellicule mince d'un fluide tel que de l'huile sur l'une des surfaces polies, avant de placer la plaque d'usure sur la surface de support. La surface finement polie, conjointement avec la pellicule mince d'huile, résultent en un joint essentiellement hermétique. La pression atmosphérique agissant sur la surface de came de la plaque d'usure sert à maintenir la plaque d'usure fermement en place sur la surface de support, de la même manière que deux cales Johansson sont maintenues ensemble si leurs surfaces finement polies sont couplées.
