Description

旋转容积式机构
技术领域
本发明涉及一种旋转容积式机构，尤其是使用于热泵中但不仅限于热泵的旋转容积式机构。
背景技术
传统小型热泵中没有从经过压缩器到蒸发器的蒸汽中回收能量。
所以有必要从处在热泵循环的压缩器和蒸发器之间的液体中回收能量。
有必要提供一种能使从压缩器中出来的蒸汽在膨胀时做功的机构。
还有必要提供一种既能完成压缩也能完成膨胀的机构。
发明内容
本发明以一种旋转容积式机构为基础，其包括：
由其圆柱体内壁面限定工作腔且具有流体进口/出口的定子；
位于工作腔中的转子，其装配成相对于定子沿上述内壁面的轴可以转动，转子具有圆柱形外壁面，上述轴通过转子，外表面的母线与所述内壁面相邻，并且沿直径相对方向的母线与上述内壁面间隔开；
沿径向突出通过定子上的槽进入到工作腔中并且可以沿径向移动的密封件，其与上述轴平行延伸且与转子的长度相同；和
使密封件的径向内端面与转子的外壁面保持相邻的装置。
本发明的一个方面是提供一种如权利要求1所述的旋转容积式机构。
本发明的另一方面是提供一种如权利要求11所述的旋转容积式机构。
附图说明
下面，参照附图并通过实施例对本发明进行进一步地描述。其中：
图1是旋转容积式机构的端面示意图，作为一个膨胀器，为简明起见，图中省略了部分视图。
图2是转子、密封件和机构相关部分的透视图；
图3是本机构中定子外壁的透视图；
图4是转子及相关部分的透视图；
图5是沿图4中V-V线的剖面图。
具体实施方式
前述旋转容积式机构具有定子或壳体1，其包含圆柱体内壁面3的外壁2。在定子1内的转子4的各个端面形成有法兰盘或圆盘形式的闸板6，圆盘6具有一个和内壁面之间仅具有很小间隙的圆柱体周缘7。圆盘6与在其之间延伸的内壁面3的部分限定成一个圆柱体工作腔，在其内部转子4可以沿内壁面3的轴8转动。转子4设置有安装在定子1端面的轴承上(未示出)的耳轴9。
转子4具有一圆柱体外壁面11，其轴12与定子1内壁面3的轴8偏心设置。轴8穿过转子4。外壁面11的母线13(包括轴线8和13的平面)与内壁面3相邻，并且具有很小的间隙。沿直径相对方向的母线与内壁面3间隔开。
在每个圆盘6附近和具有相同周缘的位置，定子1具有沿周边圆弧延伸的槽形进口14。在工作腔附近与进口14相间隔的圆周位置，定子1具有轴向槽形式的出口16。在两个口14和16之间并与它们紧邻的是密封件17，其从定子1中的槽18中径向突出以便可以在径向相对于轴8移动。密封件17平行延伸至轴8并具有与转子4实质相同的长度，在密封件17的端面和圆盘6之间仅具有很小的间隙。
为了使密封件17的径向内端面与转子4的外壁面11相邻，且不会产生过多的摩擦。一连杆19(起到连接杆的作用)一端在与轴12重合的第一接合轴处与形成转子4的延伸部分的销21活动连接，其另一端与一固定在密封件17一端的平行销22活动连接，并确定了与第一活动接合处平行的第二接合轴。通过槽18的壁面在与槽18壁上密封件17的径向导向作用下，此连接机构(19，21，22)在沿轴8旋转时，使密封件17的内端部紧随转子4的外壁面11。为达到运行平衡，在机构的另一端也设置相似的连接机构。
每个圆盘6具有进口通孔23，其在周缘7处具有第一端部23a和向工作腔内部开口的第二端部23b。这样，当第一端部23a与进口14重叠时进口14只与工作腔相连；否则，进口14被圆盘6封闭。
上述机构可以被用作热泵(未示出)中的膨胀器，所述热泵包括顺次相连的压缩器、冷凝器、膨胀器和蒸发器。从冷凝器中回收的蒸汽再次被加入到进口14中。选择构成口14的槽的圆周长度以使通孔23通过定量蒸汽所需要的时间长度符合要求。参考图1，来自通孔23的蒸汽作用在密封件17和母线13之间的转子4上的压力，促使转子4沿箭头24所示的方向转动，当转子旋转将近360°时蒸汽膨胀。同时，先前膨胀的蒸汽通过出口16被排出。
可以理解到，此机构也可以用作压缩器。而且，此机构也能用致冷剂之外的液体操作，如蒸汽、气体，特别是空气。
压缩器和膨胀器的组合可以包括两个首尾固定相接并共轴的定子和两个以可操作方式连接从而同步旋转的转子。
本领域的专业技术人员应当理解在此基础上可以作出各种变更形式而不会脱离本发明的保护范围。比如，可以省略其中一个圆盘和用形成工作腔一端的固定壁面封闭定子的端部。用弹簧代替连接机构促使密封件和转子接触。转子可以是任何适宜的圆柱形状。出口通过与进口方式相似的圆盘中的通孔来实现开启和闭合。
