带有改进的平衡活塞密封件的流体机械
摘要：
一种流体机械，具有：外部罩壳(2)，该外部罩壳(2)带有布置在其中的内部罩壳(6)、尤其为导叶承载件，和放置在其中的叶轮轴(10)；罩盖(4；8)，该罩盖(4；8)固定在外部罩壳(2)处并且将外部罩壳(2)内部中的输入压力(p1)与外部罩壳外部的环境压力(pu)分开；以及平衡活塞密封件(22)，该平衡活塞密封件(22)用于相对于输入压力(p1)无接触地密封在叶轮轴(10)和内部罩壳(6)之间限定的工作空间、尤其是压缩空间(16)中的输出压力(p2)，其中，平衡活塞密封件(22)固定在罩盖(4；8)处。
摘要（英）：

A turbo engine comprises: An outer housing (2) with an inner housing (6) arranged therein, in particular a guide vane carrier with an impeller shaft (10) arranged therein; a cover (4; 8) which is attached to the outer housing (2) and which separates an inlet pressure (p1) in the interior of the outer housing (2) from an ambient pressure (pu) outside of the outer housing; and a compensating piston gasket (22) for contactless sealing of an outlet pressure (p2) in a working chamber defined between the impeller shaft (10) and the inner housing (6), in particular a compression chamber (16), against the inlet pressure (p1), wherein the compensating piston gasket (22) is attached to the cover (4; 8).
