Description

活塞阀
技术领域
本发明涉及一种用于控制流体流的阀以及一种用于车辆的转向系统。
背景技术
在现有技术中已知在液压或气动系统中切换/控制/引导流体流的阀。
发明内容
为了引导流体流,使用包括内套筒、中套筒和阀壳体的阀。内套筒能相对于中套筒扭转,由此可实现阀的不同的切换状态。在阀壳体上设置用于将流体导入和导出的接头。因为中套筒可以相对于外套筒/阀壳体旋转超过360°,所以流体的导入和导出通过环形槽进行。为了能保证无问题的功能,过渡部构成为例如倒圆的。为此,除径向加工之外也需进行轴向加工。将轴向槽加工到中套筒的内壁上与复杂加工工艺相关。在制造技术方面,该加工工艺是复杂的,在该中套筒构成为非常小的情况下尤其如此。此外,在配套/组装/装配时对阀的“液压中心”进行调节是有问题的。为此需要耗费的控制。所述“液压中心”构成各套筒的相对设置的初始状况。在该初始状态中流体流例如直接导向到导出部中。
因此任务在于提供一种阀,该阀可简单地制成和/或其“液压中心”可简单地调节或者该阀可自动调节其“液压中心”。
作为本发明的第一实施形式提供一种用于控制流体流的阀,所述阀包括内套筒和中套筒,所述内套筒具有控制面,所述内套筒能相对于中套筒进行第一运动,所述阀具有控制活塞,通过所述第一运动实现控制活塞的第二运动,由此将阀转换到切换状态中。
通过控制活塞的设置可以省去用于引导流体流的内壁的轴向加工,由此明显简化阀的制造工艺。
作为本发明的第二实施形式提供一种用于车辆的转向系统,该转向系统包括按权利要求1至8中任一项所述的阀。
示例的实施形式在各从属权利要求中描述。
按本发明的一种示例的实施形式提供一种阀,其中,在所述切换状态中,流体流引导到第一或第二方向上,或者流体流被中断。
在按本发明的一种另外的实施形式中提供一种阀,其中,所述第一运动是扭转运动/旋转运动/轴向移动,和/或所述第二运动是扭转运动/旋转运动/轴向移动,所述轴向移动是在阀的纵轴线方向上的移动。
按本发明的一种另外的实施例提供一种阀,所述阀具有用于将控制活塞压向控制面的构件。
按本发明的一种示例的实施形式提供一种阀,其中,所述构件构成为沿着阀的纵轴线起作用。
通过将控制活塞压紧到控制面上,在控制面相对于纵轴线倾斜的合适的实施方案中,所述阀可在扭转之后自动地回到其初始状况中。所述可自动调节的初始状况可定义为“液压中心”。
按本发明的一种示例的实施形式提供一种阀,其中,所述构件是弹簧。
通过使用弹簧可以用简单的方式产生到控制活塞上的压紧力。
在按本发明的一种另外的实施形式中提供一种阀,其中,所述控制面倾斜于阀的纵轴线,和/或所述控制面通过所述第一运动为控制活塞在纵轴线方向上释放更多或更少的空间。
按本发明的一种另外的实施例提供一种阀,所述阀具有1、2、3、4、5、6、7、8个或任意多个控制活塞。
不仅通过使用任意数量的控制活塞,而且通过各个控制活塞的设计/机械构造,所述阀可以在其流体流方面根据要求被标定。
可作为本发明的构思的是,提供一种阀,该阀能通过控制活塞切换。为此可以省去阀的套筒内壁的耗费的加工。
显然各个特征也可以相互组合,由此也可部分地出现超过各单个效果总和的有利效果。
附图说明
借助在附图中示出的实施例说明本发明的其它细节和优点。附图如下:
图1示出现有技术的阀;
图2示出按本发明的阀;
图3在分解图中示出按本发明的阀;
图4示出按本发明的阀的区段的纵剖视图;
图5示出按本发明的阀的横剖视图;
图6示出用于描述扭矩和压力之间的关系的曲线。
具体实施方式
图1示出现有技术的阀,该阀包括中套筒2和内套筒1,所述内套筒1可相对于中套筒2扭转。中套筒2具有纵向槽15,这些纵向槽为了流体无问题地流入和流出而需要。纵向槽15除了需要径向加工中套筒2的内壁之外也需要中套筒2的内壁的轴向加工,这构成制造技术方面的高的费用。
图2示出按本发明的阀,该阀包括可扭转的内套筒5并且包括中套筒14。在阀壳体7上设置用于流体的导入部6和导出部12。在中套筒14中可支承控制活塞10,这些控制活塞通过弹簧9可以在轴向方向上、即在阀的纵轴线20的方向上保持在压力下并且贴靠在控制面19上。通过内套筒15的扭转/旋转,控制面19可例如在其在控制活塞10支承位置上的斜度方面发生变化并且控制活塞10可在轴向方向20上移动。通过控制活塞10的轴向移动可得到阀的切换。
图3在分解图中示出按发明的阀,该阀包括内套筒5和中套筒14,其中,在中套筒14中设置控制活塞10。这些控制活塞10通过弹簧9保持在机械压力下并且被压向控制面19。通过内套筒15的转动,控制面19也扭转并且控制活塞10可在轴向方向上移动。
图4在纵剖视图中示出按本发明的阀的区段,其包括内套筒5、中套筒14和控制活塞10。控制活塞10通过弹簧9压向内套筒5的控制面19。如果内套筒5转动,那么控制面19也移动并且控制活塞10可被朝下挤压,或者控制面19可朝上释放空间/地方并且控制活塞10可通过弹簧9被朝上挤压。因此,由此得到控制活塞的轴向移动。该轴向移动可以用于环形槽或槽11、21的连接/断开,由此可实现阀的各切换状态。在扭转之后,由于控制活塞10压紧到控制面19可实现扭转的复位,阀由此自动地转换到初始状态中。
图5在横剖视图中示出按本发明的阀,该阀包括支承在中套筒14内的控制活塞10。此外示出机械的止挡件13,该止挡件保证控制面19的最大扭转不被超过。
图6示出曲线图,该曲线图示出施加到内套筒5上的扭矩M与由此产生的在系统内的压力P之间的关系。该系统可构成为气动的或液压的。示出的是,有利地通过弹簧特性的变化(软/硬弹簧)可选择不同的特征曲线23、24。在选择特征曲线23(“软”弹簧)时通过内套筒5上的小的扭矩已经可得到高的压力变化。如果使用的是“硬”弹簧,那么通过小的扭矩只能在系统中得到小的压力变化。
值得注意的是,概念“包括”不排除其它的元件或方法步骤,并且概念“一个”也不排除多个元件和多个步骤。
使用的附图标记仅用于提高可理解性并且应在任何情况下都不视为是限制性的,其中,本发明的保护范围由权利要求书描述。
