スクロール型流体機械
Document Type and Number:
Japanese Patent JP7233935
Kind Code:
B2
Abstract:
To reduce energy loss, and to reduce load imbalance in a thrust direction of a scroll.SOLUTION: In a scroll-type fluid machine 100, a back pressure chamber H3 is partitioned into a plurality of regions (H3a, H3b, H3c) by a back face 3a1 of a movable scroll 3, a thrust receiving face 24c, and a plurality of annular seal members 19 (19a, 19b, 19c) disposed into a multiple annular shape between the back face 3a1 and the thrust receiving face 24c, and blocked in communication with the region having a pressure lower than the pressure in the back pressure chamber H3. Through holes 3d penetrated through a second bottom plate 3a of the movable scroll 3 in a plate thickness direction, are opened corresponding to each of the regions (H3a, H3b, H3c) of the plurality of regions. Each region of the plurality of regions is communicated with a sealed space S to which the through hole 3d is opened, among the plurality of sealed spaces S through the through hole 3d corresponding to the region.SELECTED DRAWING: Figure 1
