    • The present invention relates to a set (1) of plates (2, 3; 12, 13; 21, 22; 41) or parts obtained by cutting a block (4, 4'', 4''', 35) of metal or composite material extending around a plane (5) comprising a first plate (2, 12, 21, 41) or part having an upper face (7, 33) and a second plate (3, 13, 22) or part having a lower face (8). The upper face (7, 33) of the first plate (2, 12, 21, 41) or part has a surface (7, 330) having at least two lines of inflection or changing slope with respect to said plane (5), and the lower face (8) of the second plate (3, 13, 22) or part has a surface (8) with a shape complementary to the upper face (7, 33) of the opposite first plate (2, 12, 21, 41) at a more or less constant height, corresponding to the height of the cutting line (34) in the block (4,35).
    • 本发明涉及板的一组(1)通过切割金属或复合材料的块(4,4”,4" ”,35)中获得或部件(2,3; 41 12,13; 21,22) 材料的平面(5),包括第一板(2,12,21,41)或部分上具有上表面(7,33)和周围延伸的是第二板(3,13,22)或具有下表面部分( 8)。 所述第一板(2,12,21,41)或部分的上表面(7,33)具有一个表面具有拐点的至少两行或改变相对于坡所述平面(7,330)(5) 和第二板(3,13,22)或部分的下表面(8)具有一个表面(8)具有一个形状与所述相对的第一板(2,12的上表面(7,33)互补, 21,41)在或多或少恒定的高度,相应的,在块(4.35)的切割线(34)的高度。

    • 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).
    • 本发明涉及一种纵向延伸的活塞式发动机的汽缸盖,元件和法兰,其包括位于至少一个元件(6)上的活塞头本体(4)和法兰(5),法兰(5)用于 其设置在燃烧室与活塞头本体(4)之间,该活塞头本体(4)包括面对活塞头本体(4)的上表面(7)和面对燃烧室布置且相对的下表面(8) 所述活塞头本体(4)由密度和硬度小于构成所述凸缘(5)的材料的密度和硬度的材料制成。 法兰(5)和主体(4)通过螺栓(12)装配,用于将法兰(5)固定在朝向法兰(5)和主体(4)的边缘定位的活塞头(4)上,并且 通过用于将活塞头(4)紧固在法兰(5)上的至少一个部分(16)包括用于紧固在法兰(5)的对应孔(18)中的螺纹端部(17),所述孔(18) 比紧固螺栓(12)更靠近底板(5)的中心。
