    • This invention provides a cylinder head capable of efficiently cooling the portion at which a large number of valve ports gather. The present invention provides a cylinder head (20) of an engine equipped with suction and exhaust valve ports (3a, 5a) inside a cooling jacket (8), characterized in that a drain port (11) allowing the cooling water jacket (8) to communicate with the outside of the cylinder head (20) opens in a corner portion at one end portion of a side wall (1a) of the cylinder head, water feed ports (10a) extending along the side wall (1a), opening to the cooling water jacket (8) and communicating with the cooling water jacket of the cylinder block are formed in a cylinder head bottom wall (1c), and a partition is so disposed as to divide the portion at which the water feed ports (10a) are open and the portion at which the suction and exhaust valve ports (3a, 5a) are disposed and to guide cooling water from the water feed ports (10a) round the suction and exhaust valve ports (3a, 5a).

    • A ceramic valve supporting structure comprising in use for internal combustion engine; a ceramic valve (1) having an integral stem (1b), the upper portion of which is provided with a circular groove (2); a cotter (3) the outer surface of which is tapered, and formed by butting a pair of semi-cylindrical pieces, and having a lock projection (3a) placed into the groove (2) when secured concentrically to the outer surface of the stem, a cylindrical retainer (4) concentrically secured to the cotter surface of the cotter so as to support the valve (1) through the cotter (3); the retainer (4) being provided with the inner surface tapered in a direction so as to make the cotter (3) tightly engage with the outer surface of the stem (1b) by means of wedge effect against the tapered cotter (3) due to the urging force of a coil spring member (6) axially exerted to the retainer (4); and a stress relief means provided so as to avoid the predetermined portion of the cotter from locally engaging against the outer surface of the stem. Stress relief is provided by a bevelled portion (4c) at the end of the retainer (4) adjacent the valve head to provide a clearance between the retainer (4) and cotter (3) at the end of the cotter.
    • 一种用于内燃机的陶瓷阀支撑结构, 陶瓷阀(1),其具有一体的杆(1b),其上部设有圆形槽(2); 其外表面是锥形的,并且通过对接一对半圆柱形件形成,并且当与所述杆的外表面同心地固定时,具有放置在所述槽(2)中的锁定突起(3a) 同心地固定在开口的开口表面上以便通过开口(3)支撑阀(1)的圆柱形保持器(4); 所述保持器(4)具有沿着使所述开口(3)通过对所述锥形开口(3)的楔形作用与所述杆(1b)的外表面紧密接合的方向成锥形的所述内表面, 螺旋弹簧构件(6)的作用力轴向地施加到保持器(4)上; 并且设置有应力消除装置,以避免开口器的预定部分局部地接合在杆的外表面上。 应力释放由邻近阀头的保持器(4)的端部处的倾斜部分(4c)提供,以在保持架(4)和开口(3)之间在孔口端部提供间隙。
