Description

具有柱塞的泵体
技术领域
本发明涉及用于净水器的高压液泵。
背景技术
通常作为柱塞而为人所知的这些泵具有一泵头、一与所述泵头分开的本体和用来将所述泵体固定在驱动马达体上的装置，管道在所述泵头中形成，并且进气阀和排气阀位于所述泵头中，一个或多个活塞的促动装置位于所述本体中。
特别是，马达的驱动轴插入泵体中从而扭转地锁定外周上的旋转倾斜板中心(hub)的中空突出部分(tang)，活塞的端部在该外周中滑动。
为了避免摩擦，活塞的端部位于旋转环中，同时辊子置于倾斜板中。
倾斜板中心的中空突出部分通过滚动球轴承依次由泵体支撑。
在公知的泵中，由一成形盖在马达侧将泵体封闭，所述成形盖承载着马达体的连接壁，并起着支承倾斜板中心的中空突出部分的轴承座的作用，并用作油密封垫的座。
然后通过外周的螺栓将盖连接在泵体上。
公知的技术方案具有许多缺陷，这些缺陷为结构的复杂性和泵组装的困难。
发明内容
本发明的目的是用一种简单、节约成本并可靠的技术方案来克服所述的缺陷。
该目的通过由本发明的具有柱塞的泵的技术方案来实现。
本发明提供了一种具有柱塞的泵，其包括泵头、与所述泵头相关的泵体，进气和排气管道和相应的进气和排气阀在泵头中形成，至少一个活塞的驱动装置和驱动马达体上的所述泵体的连接支承装置位于所述泵体的外周面上，其中，所述泵体在底壁上具有用于活塞滑动的座，并且所述泵体直接承载驱动马达体上的所述连接支承装置，其在面向马达的边缘上完全开放。
本发明的具有柱塞的泵阐明了有利的结构上的详细特征。
基本上，该目的通过直接承载驱动马达体的所述连接支承装置的泵体来实现的，这就使得能够去掉盖。
参照附图，通过以下详细地描述，本发明的优点和结构及功能特征将变得清楚，图中示出了一个优选实施例作为非限定性示例。
附图说明
图1为泵的轴向截面图。
具体实施方式
在图中，能够看到泵的泵头1，其中液体的进气和排气管道2、3及相应的进气和排气阀的阀座22、23在泵头中形成。
泵体4为杯状，并直接承载着例如为吸热型或燃烧型的驱动马达体的连接支承装置，图中未示出。
在示例中，所述连接支承装置的形式为靠近本体4的开放端而设置的三个间隔120°的支架5。
本体4的底壁40具有用于活塞6的滑动座41，这些滑动座在泵头1内伸展，用于容纳在泵头1的凹槽21中的部分61。
底壁40还包括用于将泵头1固定在本体4上的接收螺栓44(receiving bolt)的外周座43。
每个活塞座包括一个容纳在泵头1的凹槽21中的密封垫62、一个容纳在泵头1中的杯状罩63和一个容纳在泵体4中与所述罩63邻近的油密封件64。
在本体4中伸展的活塞6的端部60放置在环7上，由于插入辊子71，环7在旋转倾斜板8上自由旋转。
弹簧65与盘状物66使活塞与环7保持接触。
旋转倾斜板8具有一个中空突出部分81，该中空突出部分81通过轴承与泵体4连接，轴承通过弹性圈91保持在适当的位置上，弹性圈91在轴向上相对于泵体4锁紧轴承9。
垫10将本体4的内部与外部隔开。
突出部分81的凹槽82通过键的插入(图中未示出)容纳电机轴。
前述的结构还允许进行有益的组装过程。
除了阀之外，密封垫62和罩63也可以预先安装在泵头1中。
另一方面，按照图中从右方开始的顺序，泵体4容纳活塞6、弹簧65、相对的盘状物66、包括旋转倾斜板8和环7的组、轴承9、弹性圈91和垫10。
在安装油密封件64之前，通过螺栓44将泵头1固定在本体4上，并且所有的部件都准备好以便通过支架5固定在电机的本体上。
如从所描述的内容中可以清楚地看出的那样，按照本发明的具有柱塞的泵体能够满足需要，并且能克服说明书的引言部分中所提到的现有技术的缺陷。
实际上，本发明的具有柱塞的泵体非常容易制造，并且相对于现有技术的泵体具有非常少的组装难度。
当然，本领域普通技术人员可以对上述具有柱塞的泵体作出许多变化或改动以满足可能的和特定的需要，所有的这些变化或改动都落入权利要求书所限定的保护范围内。
