摘要： PROBLEM TO BE SOLVED: To prevent a drop of operating fluid pressure by maintaining oiltightness at a connecting face of an operating fluid supply line in an internal combustion engine using a cylinder head cover made of resin and mounted with oil control valves (OCVs) for supplying the operating fluid to a valve timing adjusting mechanism.
SOLUTION: A connecting body 6 is integrated along the plate face of a cylinder head cover body 4 made of resin, to connect the OCVs 8, 10 to each other. The OCVs 8, 10 are thereby maintained firmly on the positions on the cylinder head cover body 4. Moreover, since the connecting body 6 is formed of a metallic material, rigidity of the cylinder head cover 2 made of resin can be enhanced to suppress deformation caused by a temperature change and an internal pressure change, particularly deformation around the mounted positions of the OCVs 8, 10. Consequently, oiltightness of the connecting face between the operating fluid supply line in the cylinder head cover body 4 and an operating fluid supply line on the cylinder head side for connection to ports of the OCVs 8, 10 is maintained to a high degree.

摘要： PROBLEM TO BE SOLVED: To reduce the number of parts in a resin-made cylinder head cover of an internal combustion engine and solve a problem of an oil seal. SOLUTION: Hydraulic fluid pressure supply oil passages 66, 67 and distribution oil passages 66a, 66b are formed by the same resin in a resin-made cylinder head cover main body 4 by integral molding. For this reason, since each oil passage 66, 67, 66a, 66b is completely integrated with the resin-made cylinder head cover main body 4 and has high affinity, each oil passage 66, 67, 66a, 66b is firmly fixed to the resin-made cylinder head cover main body 4 and is not lifted from a surface of the resin-made cylinder head cover. Consequently, special parts such as a union bolt and an oil joint are unnecessary to suppress the number of parts to the minimum number, and resonance phenomenon accompanying the operation of the internal combustion engine is effectively prevented to solve the problem of the oil seal.

摘要翻译：要解决的问题：为了减少内燃机的树脂制气缸盖的部件数量并解决油封的问题。解决方案：液压流体压力供给油通道66,67和分配油通道66a，66b通过一体成型在树脂制气缸盖罩主体4中由相同的树脂形成。因此，由于各油路66,67,66a，66b与树脂制气缸盖罩主体4完全一体化并且具有高亲合力，所以每个油路66,67,66a，66b牢固地固定在树脂上制造的气缸盖罩主体4，并且不从树脂制气缸盖罩的表面提升。因此，不需要诸如联合螺栓和油接头的特殊部件来将部件数量抑制到最小数量，并且有效地防止伴随内燃机的操作的共振现象来解决油封的问题。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a sleeve for mounting an oil control valve capable of facilitating highly precise machining and driving a variable valve train of an internal combustion engine and to provide a cylinder head cover using the sleeve.
SOLUTION: High machining precision becomes unnecessary in a resin-made cylinder head cover main body 4 and resin-made caps 14, 16 other than the sleeves 10, 12 by applying the sleeves 10, 12 provided with connection parts 26, 32 for supplying and exhausting hydraulic fluid pressure integrally to the cylinder head cover. Since the connection parts 26, 32 for supplying and exhausting hydraulic fluid pressure are integrally formed even in the sleeves 10, 12, only mounting holes 24c, 30c in which the oil control valve is mounted require, in particular, high machining precision. Consequently, burden by highly precise machining is further reduced. Influence among a plurality of precise machining sections is eliminated, and influence in dimensional precision on the mounting holes 24c, 30c due to cutting resistance is also eliminated. In this way, the sleeves 10, 12 facilitate highly precise machining.

摘要翻译：要解决的问题：提供一种用于安装能够促进高精度加工和驱动内燃机的可变气门机构的油控制阀的套筒，并且使用套筒提供气缸盖盖。
解决方案：通过施加设置有连接部26,32的套筒10,12，树脂制气缸盖罩主体4和除了套筒10,12之外的树脂制帽14,16，不需要高加工精度用于将液压流体压力一体地供给和排出到气缸盖罩。由于用于供给和排出液压流体压力的连接部26,32即使在套筒10,12中也一体地形成，因此仅安装有油控制阀的安装孔24c，30c特别需要高加工精度。因此，进一步降低了高精度加工的负担。消除了多个精密加工部的影响，也消除了由于切削阻力而对安装孔24c，30c的尺寸精度的影响。这样，套筒10,12便于高精度的加工。版权所有（C）2006，JPO＆NCIPI

In addition, the lateral movement of the float valve 50 is restricted by the lateral movement restricting pin 43P so that a top portion of an upper surface bulged portion 51 vertically constantly faces an inside area of a valve seat 33. Thus, the float valve 50 can be vertically miniaturized in a disc shape of functioning as a valve element and a floating body.
