本申请要求在2006年12月7日提交韩国知识产权局的韩国专利申请10-2006-0124072的优先权和权益，其全部内容在此引用作为参考。
技术领域
本发明涉及一种用于停缸系统的供油管路。更具体地，本发明涉及一种通过在凸轮轴的空腔中形成油路的用于停缸系统的供油管路，其具有简单的结构且能够安装在气缸盖上而无需附加的外部元件。
背景技术
停缸系统是根据驾驶条件停止不必要气缸的系统。该停缸系统可以通过停止不必要气缸而改善燃料消耗率。
根据该停缸系统，通过根据驾驶条件向控制进入和排放门(intakeand exhaust valves)开度的支顶件(tappets)提供高压油或低压油而控制进入和排放凸轮的操作。
即，当向支顶件提供高压油时，凸轮旋转但气门不操作。另一方面，当向支顶件提供低压油时，凸轮旋转且气门也操作。
根据传统的停缸系统，用于向支顶件提供高压油或低压油的供油管路可以比较复杂，且可以需要额外的外部元件，从而将供油管路安装在气缸盖上。
上述在该背景技术部分公开的信息仅用于加深对发明背景的理解，因此它可能含有不构成在该国中本领域普通技术人员已知的现有技术的信息。
发明内容
本发明的目的是提供一种用于停缸系统的供油管路，以通过在始终装在气缸盖上的凸轮轴空腔中形成油路而简化其的结构。

所述第一油路可以包括：用于向第一和第二气缸的支顶件提供高压油的第一高压供油管路；和用于向第三和第四气缸的支顶件提供高压油的第二高压供油管路。
所述第一高压供油管路可以通过从供油管路分支的油岐管(oilbifurcation line)连接至所述第二高压供应管路。
所述第一高压供油管路可以包括：第一控制阀，其连接至供油管路并控制油供应；第一排放侧(a first exhaust-side oil supply)供油管路，其连接至所述第一控制阀并向所述第一和第二气缸的排放侧支顶件供油；和第一进入侧供油管路，连接至所述第一控制阀并向所述第一和第二气缸的进入侧支顶件供油。
所述第二高压供油管路可以包括：第二控制阀，其连接至油岐管并控制油供应；第二排放侧供油管路(a second exhaust-side oilsupply)，其连接至所述第二控制阀并向所述第三和第四气缸的排放侧支顶件供油；和第二进入侧供油管路，其连接至所述第二控制阀并向所述第三和第四气缸的进入侧支顶件供油。
从第一油路向支顶件提供的油可以通过节流孔(orifice)向油路提供。

具体实施方式
下面将结合附图，详细说明根据本发明一个实施例。
图1是表示根据本发明实施例用于停缸系统的供油管路安装在气缸盖上的顶视图。
如图1中所示，根据本发明一个实施例用于停缸系统的供油管路被安装在气缸盖100上。凸轮轴110和多个支顶件130被安装在气缸盖100的上表面上。凸轮轴110旋转并控制支顶件130的运动。支顶件130垂直地往复运动并控制进入和排放门(图中未表示)的开度。
图2是根据本发明实施例用于停缸系统供油管路的示意图，图3是图2中第一高压供应管路的放大视图，而图4是图2中第二高压供应管路的放大视图。
如图2中所示，根据本发明一个实施例用于停缸系统的供油管路包括液压泵240，多个支顶件130，第一油路280，和第二油路270(如图1中所示)。
液压泵240通过第一油路280和第二油路270向支顶件130供油。液压泵240通过供油管路250连接到第一油路280。此外，液压泵240通过供油管250向张紧装置(tensioner)210、可变气门正时装置(variable valve timing apparatus)220和轴承(bearing)230供油。
支顶件130从液压泵240接收油并控制进入和排放门的开度。
第一油路280通过供油管路250连接至液压泵240。第一油路280向支顶件130提供高压油。第一油路280包括用于向第一和第二气缸的支顶件130提供高压油的第一高压供油管路290，及用于向第三和第四气缸的支顶件130提供高压油的第二高压供油管路300。
此外，第一高压供油管路290通过从供油管路250分支的油岐管170连接至第二高压供油管路300。
第一高压供油管路290，如图2和图3中所示，包括第一控制阀140，第一排放侧供油管路150，和第一进入侧供油管路160。
第一控制阀140连接至供油管路250并从供油管路250接收高压油。第一控制阀140根据发动机控制单元(图中未表示)的控制信号控制第一和第二气缸的排放侧和进入侧支顶件130的油供给。
第一排放侧供油管路150连接至第一控制阀140并接收油。此外，第一排放侧供油管路150向第一和第二气缸的排放侧支顶件130供油。
第一进入侧供油管路160连接至第一控制阀140并接收油。此外，第一进入侧供油管路160向第一和第二气缸的进入侧支顶件130供油。
第二高压供油管路300，如图2和图4中所示，包括第二控制阀180，第二排放侧供油管路190，和第二进入侧供油管路200。
第二控制阀180连接至从供油管路250分支的油岐管170并接收油。第二控制阀180根据发动机控制单元(图中未表示)的控制信号控制向第三和第四气缸的排放侧和进入侧支顶件130提供的油。
第二排放侧供油管路190连接至第二控制阀180并接收油。此外，第二排放侧供油管路190向第三和第四气缸的排放侧支顶件130供油。
第二进入侧供油管路200连接至第二控制阀180并接收油。此外，第二进入侧供油管路200向第三和第四气缸的进入侧支顶件130供油。

油路120通过节流孔260向支顶件130供油。
此外，当油流过节流孔260时，从第一油路280向支顶件130提供的高压可以在油压降低后向油路120提供。
根据本发明，形成在凸轮轴中的油路始终安装在气缸盖上，从而供油管路的结构可以简化。
此外，由于油路形成在凸轮轴中，供油管路可以安装在气缸盖中，而无需附加外部元件。
尽管已经结合一个实际实施例对本发明作了说明，但可以理解的是，本发明并不局限于公开的实施例，相反，本发明涵盖各种包括在文中所附的权利要求的精神与范围中的改进和等价的布置。
