Cylinder head, element and flange of a piston engine

Abstract: The present invention relates to a cylinder head, an element and a flange of a longitudinally extending piston engine comprising a piston head body (4) and a flange (5) on at least one element (6), the flange (5) being to interpose between a combustion chamber and the piston head body (4), comprising an upper face (7) facing the piston head body (4) and an opposite lower face (8) to be arranged facing the combustion chamber and being attached on the piston head body (4), the piston head body (4) being made from a material with a density and hardness that is less than those of the material constituting the flange (5). The flange (5) and the body (4) are assembled by bolts (12) for fastening the flange (5) on the piston head (4) located towards the edge of the flange (5) and of the body (4) and by at least one part (16) for fastening the piston head (4) on the flange (5) comprising a threaded end (17) for fastening in a corresponding hole (18) of the flange (5), said hole (18) being situated closer to the centre of the baseplate (5) than the fastening bolts (12).

Culasse, element et semelle de moteur a piston.

Abstract: La presente invention concerne une culasse, un element et une semelle de moteur a piston s'etendant longitudinalement comprenant un corps (4) de culasse et une semelle (5) en au moins un element (6), la semelle (5) etant a interposer entre une chambre de combustion et le corps (4) de culasse, comportant une face (7) superieure en vis-a-vis du corps (4) de culasse et une face (8) inferieure plane opposee a disposer face a la chambre de combustion et etant rapportee sur le corps (4) de culasse. Le corps de culasse est en un materiau d'une masse volumique et d'une durete plus faibles que celles du materiau constitutif de la semelle (5). La semelle (5) et le corps (4) sont assembles par des vis (12) de fixation de la semelle (5) sur la culasse (4) situees vers la peripherie de la semelle (5) et du corps (4) et par au moins une piece (16) de fixation de la culasse (4) sur la semelle (5) comprenant une extremite (17) filetee de fixation dans un orifice (18) correspondant de la semelle (5), ledit orifice (18) etant situe plus proche de la semelle (5) que les vis (12) de fixation.
