WIPO Patent Application WO/2019/035276
Kind Code:
A1
Abstract:
In this scroll fluid machine, a tip seal (7) that is in contact with facing end plates (5a) and that is for sealing in a fluid is provided to a tip seal groove (3d) formed on the tooth tip of a wall (3b). The tooth bottoms of the end plates (5a) have a shape in which a central section is deeper than a side section (5d3) in a width direction orthogonal to the spiral direction of a wall (5b). During operation, the protrusion amount (δ) when the tip seal (7) protrudes from the tooth tip of the wall (3b) in an inclined section and is in contact with the facing end plates is greater than the protrusion amount (δ) when the tip seal (7) protrudes from the tooth tip of the wall (3b) in a flat section and is in contact with the facing end plates.
