Description

用于凸轮轴调整器的控制阀
技术领域
本发明涉及一种依照权利要求1前序部分的用于如下装置的控制阀，该装置用于对内燃机中的换气阀的配气相位进行可变调整。
背景技术
由DE 102005052481A1例如公知了类属的控制阀。在这里，对压力介质的过滤借助配属于输入通道的单独的过滤器来进行和/或通过使用分油套管来进行。这些解决方案的不利之处在于，由于另设的分油套管，在装配分油套管时使得碎屑风险有所提高，其中，这些碎屑可能进入压力介质引导通道或者以如下方式妨碍部件彼此相对运动，即，阀不再能够实现其功能。另外，单独的过滤器的应用在制造和装配中是很昂贵的。
发明内容
本发明的任务在于，实现一种有待成本低廉地制造和装配的控制阀，该控制阀具有改善的功能可靠性。
根据本发明，该任务通过具有权利要求1特征的控制阀来解决，其中，有利的构造方案和改进方案在从属权利要求中给出。
根据本发明提出：压力介质引导插入件具有引导套管，控制活塞在该引导套管内引导，该引导套管具有塑料包铸部，在该塑料包铸部中布置有压力介质引导通道中的至少两个，并且在塑料包铸部与引导套管之间设置有滤网。
本发明的基本设想在于，带有引导套管和包铸部的压力介质引导插入件具有两件式的结构并且在这两个部件之间设置有滤网。由此，对于压力介质所需的过滤器已整合到压力介质引导插入件中，从而取消了基于迄今所需的单独部件的碎屑风险以及制备开支和装配开支。另外，本发明提供如下优点，即，过滤器尽可能接近于压力介质引导插入件的控制边缘地布置，从而该控制边缘尽可能好地受到保护以免于污染颗粒的损害。
另外设置为：将滤件配属于至少两个压力介质引导通道，其中，还提出：将所述滤网配属于至少一个流入通道和流出通道。由此，能够以非常低的开支在压力介质引导通道中仅利用单个的滤网对压力介质进行过滤。因此，与现有技术相比，实现了明显增大的滤面，由此实现了对压力介质更好的净化。
滤网可以在包铸之后分区段地在两侧由包铸部包围，由此，两个部件的连接得到强化。
滤网还可以呈软管状地构造，从而该滤网在固定于引导套管上并且在进行包铸之后自动地配属于压力介质引导通道的所有外周侧开口。由此实现了尽可能大的滤面并且利用仅一个滤网来保护所有的控制边缘。
控制阀的结构可以进一步得到简化，方法是：包铸部在其朝向凸轮轴的端部上具有用于止回阀的引导部。由此，取消了控制阀内迄今所需的插件并且控制阀的部件数目得到进一步降低。
引导套管可以构造为钢制件，并且一方面用作布置于其中的控制活塞所用的引导元件，以及另一方面用作包铸而成的两件式压力介质引导插入件中的形状稳定部件。
滤网能够以可弹性扩展的方式构造，从而滤网在扩展的情况下可以套装到引导套管上。另外，滤网由此可以接纳来自变换的压力介质流的可能的负载，而不会存在突然的不可预见的断裂的危险。
滤网可以由成本低廉的塑料制成，从而可以利用塑料包铸来熔制滤网。
另选地，同样可以应用由不锈钢制成的钢网，这在压力介质的温度以及所出现的持续荷载方面是有利的。
另外提出，所述网具有菱形的开口。由此，该网的可扩展性不依赖于该网的材料特性地给出。
附图说明
下面，结合优选实施例来详细介绍本发明。附图分别为：
图1示出一种装置，该装置用于对带有根据本发明的控制阀的内燃机的换气阀的配气相位进行可变调整；
图2示出控制阀，该控制阀具有带整合的过滤器的压力介质引导插入件；
图3示出带整合的网的压力介质插入件。
具体实施方式
在图1中示出用于对内燃机的换气阀的配气相位进行可变调整的装置，该装置具有传动轮6，该传动轮6与定子7抗扭地连接。另外，设置有转子8，转子8与凸轮轴4抗扭地连接。传动轮6直接或间接地由内燃机的曲轴驱动。接着，传动轮6的转动运动通过定子7传递到转子8，从而与转子8抗扭地连接的凸轮轴4同样发生转动。于是，转动的凸轮轴4对内燃机换气阀的开启时间和关闭时间进行控制。于是，对换气阀控制时间的调整就通过转子8相对于定子7的相对转动来进行，该相对转动通过控制阀1来控制。
在图2和图3中，可以看到控制阀1和控制阀1的压力介质引导插入件10。控制阀1包括凸轮轴侧的压力介质输入部“P”和布置在背向凸轮轴4的端部上的压力介质输出部“T”。另外，设置有两个工作接口“A”和“B”，这两个工作接口“A”和“B”同转子8与定子7之间的压力室连通。在控制阀1中布置有压力介质引导插入件10，该压力介质引导插入件10具有压力介质引导通道11、12、13、14，所述压力介质引导通道11、12、13、14在流体技术上与输入接口“P”、输出接口“T”以及工作接口“A”和“B”连接或者能够与它们连接。控制活塞3在压力介质引导插入件10中可推移地引导。于是，根据控制活塞3的位置，而产生压力介质输入部“P”与工作接口“A”和“B”或压力介质输出部“T”之间的连接。在这里不应进一步关于控制方案进行详细探讨，这是因为该控制方案属于现有技术并且例如在DE 102005052481A1中已充分介绍。由此，对于本发明的理解直接参引DE 102005052481A1的公开内容。
压力介质引导插入件10具有两件式的结构，包括引导套管15和包铸部16。引导套管15设有开口14，开口14能够通过在引导套管15内侧引导的控制活塞3来进行封闭。包铸部16在外侧设有压力介质引导通道11、12和13。全部压力介质引导通道11、12、13以及开口14都设有滤网17，将滤网17整合到压力介质引导插入件10中。滤网17在包铸之前布置在引导套管15上，从而在包铸之后，滤网17自身便是压力介质引导插入件10的组成部分。滤网17呈软管状地构造并且由此在扣到引导套管15上并且进行包铸之后自动地遮盖所有在外周侧布置于压力介质引导插入件10中的压力介质通道11、12、13以及遮盖开口14，其中，这与所述压力介质通道及开口的数目、几何形状及布置方案无关。滤网17在其朝向凸轮轴4的端部19上在两侧由包铸部包住，从而在这里实现了包铸部16与滤网17之间特别强的型体连接。
另外，在所述压力介质引导插入件10上，在其朝向凸轮轴4的侧上设置有用于输入通道“P”中的止回阀5的封闭体21的引导部18。引导部18通过从外部可触及的开口来形成，可以将封闭体21引入该开口中。在将封闭体21导入之后，密封部件21从外部与包铸部16连接。封闭体21在止回阀5关闭的情况下以用弹簧加载的方式贴靠在密封部件20上。关于如何产生弹簧负载的作用与类型，参引DE 102005052481A1。由此，控制阀1的零件数目再次得以减少，其中，附加地实现了如下优点，即，止回阀5连同压力介质引导插入件10一起可以作为结构组件以预装配的方式制造和装配。引导部18在其具有弹簧穿过部的端部变细，从而封闭体21在引入引导部18后并且固定密封部件20之后防脱失地接纳在引导部18中。
