Description
技术领域
本发明涉及一种根据独立权利要求1前序部分所述的用于流体泵的脉动缓冲元件,以及相应的具有该脉动缓冲元件的流体泵。
背景技术
例如被实施为活塞泵的流体泵在具有车辆液压或电液制动系统的车辆中优选地被用作回油泵,以选择性地降低或升高在车轮制动缸中的制动压力,由此可调节车轮制动缸中的制动压力。例如可以在防抱死系统(ABS)中、在驱动防滑控制系统(ASR系统)中、在行驶动力学控制系统中执行这种调节。
例如在公开文献DE 10 2007 047 417 A1中描述了一种传统的活塞泵,其包括活塞组件、吸入阀、排出阀及缸体。吸入阀通常是止回阀。排出阀也同样是被弹簧加载的止回阀并且设置在活塞泵的盖元件中。当在压缩室中的压力大于排出阀弹簧作用在排出阀的排出阀密封元件上的弹簧力时,由此排出阀密封元件从设置在缸体的出口上的排出阀座上被压开,排出阀被打开。
为了减小压力脉动,传统的活塞泵可以配备有脉动缓冲元件,该脉动缓冲元件具有由橡胶制成的膜或被实施为橡胶/钢部件。
发明内容
与此相对地,具有独立权利要求1特征的根据本发明的脉动缓冲元件的优点为,通过提出的构造方式,压力峰值可以最优地在小的结构空间内被吸收,从而能够以有利的方式在低压范围内以及在高压范围内减小压力脉动。在压力很低时根据本发明的脉动缓冲元件已经变形,因此在压力脉动很小时反应快速且精确。然而,通过波纹管基体,根据本发明的脉动缓冲元件的实施方式也可以在强度/蠕变强度方面经受住高压范围,其中最优地设计波纹管基体的弹性特性以吸收压力脉动。总的来说,以有利的方式实现根据本发明的脉动缓冲元件的小的安装空间和成本低且简单的制造。
用于流体泵的根据本发明的脉动缓冲元件包括具有波纹管基体的盆状减振器,在该波纹管基体中设置有以弹性的填充物填充的间隙,所述填充物执行弹簧元件的功能,从而可在波纹管基体因压力脉动而产生运动时压缩所包围的空气容积以吸收压力脉动。通过间隙的数目和/或大小或通过所使用的弹性填充材料的种类能够以有利的方式预先设定所述盆状减振器的弹性特性。
根据本发明的脉动缓冲元件例如可以被安装在流体泵的泵壳体中或盖件中,优选地是安装在排出阀盖件中。
通过在从属权利要求中描述的措施和改进方案可以有利地改进在独立权利要求1中所述的脉动缓冲元件和在独立权利要求9中所述的流体泵。
特别有利的是,波纹管基体在一端由盆底部封闭以形成盆状减振器。盆底部能够以有利的方式被实施为用于密封元件的支撑件和/或被实施为流体泵的优选为流体泵的排出阀的密封元件。密封元件例如可以是密封球和/或密封球冠和/或密封板。在此处,密封元件可以固定地或可运动地与被实施为支撑件的盆底部连接或者模制在盆底部上。这种措施能够以有利的方式实现流体泵的特别紧凑的结构,因为脉动缓冲元件例如可以被集成在流体泵的排出阀的结构空间中。当脉动缓冲元件还执行用于流体泵的排出阀的复位弹簧的功能时,实现了对以供使用的结构空间的进一步优化的利用。
在根据本发明的脉动缓冲元件的有利设计方案中,波纹管基体在另一端具有稳固的端部区域,该端部区域在安装脉动缓冲元件时能够以有利的方式作为有效直径用于压入过程和/或密封填密过程。
在根据本发明的脉动缓冲元件的另一有利的设计方案中,盆状减振器由合成材料注塑而成,或由优选为钢的金属成型而成。可以使用优选为三元乙丙橡胶的弹性的合成材料作为在波纹管基体的间隙中的填充物。
在根据本发明的流体泵的一种有利的设计方案中,脉动缓冲元件为流体泵的排出阀的复位弹簧元件。
脉动缓冲元件可以作为用于吸收压力脉动的单纯的减振器元件来使用或者用作复位弹簧、减振器和/或密封元件,该密封元件可以被安装在排出阀盖件中。因此脉动缓冲元件可以完全直接安装在流体泵内或者在外部安装在壳体或泵盖件中。
附图说明
本发明的有利的实施方式在附图中示出并在以下进行说明。在附图中,相同的附图标记表示执行相同或相似功能的组件或元件。
图1示出了具有根据本发明的脉动缓冲元件的第一实施方式的流体泵在排出阀区域中的示意性剖视图。
图2示出了图1中根据本发明的脉动缓冲元件的第二实施方式的示意性剖视图。
图3示出了图1中根据本发明的脉动缓冲元件的第三实施方式的示意性剖视图。
具体实施方式
如图1所示,根据本发明的用于流体泵1的脉动缓冲元件3包括盆状减振器10,该盆状减振器具有波纹管基体14,在该波纹管基体中根据本发明设置有用弹性填充物20填充的间隙14.1。在此处,填充间隙14.1的填充物20执行弹簧元件的功能,使得在波纹管基体14因压力P的脉动而产生运动时压缩所包围的空气容积18以吸收压力脉动。
在示出的实施方式中,脉动缓冲元件3被集成在流体泵1的排出阀的盖件5中并附加地执行用于排出阀的密封元件9的复位弹簧的功能,其中密封元件9封闭或打开流体泵1的泵缸7的出口。
如图1进一步所示出的,波纹管基体14在一端由盆底部16封闭以形成盆状减振器10,该盆底部是用于流体泵1的排出阀的密封元件9的支撑件16。在示出的第一实施方式中,所述密封元件9为球体,其中盆底部16例如可以具有相应的凹部用于可运动地为球状的密封元件9导向。
波纹管基体14在另一端具有稳固的端部区域12,该端部区域在安装脉动缓冲元件3时可以作为有效直径12.1用于压入过程和/或密封填密过程。在此处,例如为突出的凸缘的稳固的端部区域12在排出阀盖件5的压入区域5.1中流体密封地被压入。代替地,稳固的端部区域12可以在与排出阀盖件5的填密区域流体密封地被填入。
图2示出的脉动缓冲元件3′的第二实施方式与图1的脉动缓冲元件3的第一实施方式的区别之处仅在于,被实施为密封球冠的密封元件9′与盆状减振器10′的被实施为支撑件的盆底部16′固定地连接。因此,在此处可以略去对功能相同的部件的重复说明。
图3示出的脉动缓冲元件3″的第三实施方式与图1的脉动缓冲元件3的第一实施方式的区别之处仅在于,盆底部16″本身为密封板形式的密封元件9″。因此,在此处可以略去对功能相同的部件的重复说明。
盆状减振器10、10′、10″可以例如由合成材料注塑而成,或由优选为钢的金属成型而成。例如可以使用优选为三元乙丙橡胶的弹性的合成材料作为在波纹管基体14的间隙14.1中的填充物20。
本发明的实施方式通过使用具有间隙的波纹管基体既在低压范围又在高压范围内减小了压力脉动,所述间隙由弹性填充材料填充并可实现波纹管运动。在压力脉动很小时这种脉动缓冲元件的反应快速且精确,并且由于其结构在高压范围也被保护免于损坏。因此,压力峰值可以最优地在小的结构空间内直接在泵中或在外部被吸收。
