| 102 | Pressure seal for a vacuum pump | US10110967 | 2002-04-18 | US20020155014A1 | 2002-10-24 | Pascal Durand; Emmanuel Bourgeois |
| The invention concerns a vacuum pump consisting in the assembly of two stator half-shells (101, 102) and two directly mounted end parts (31, 32) with an interposed single-piece continuous pressure seal (33). The pressure seal (33) comprises two annular end parts (34, 35) generally parallel to each other and connected by two side-members (36, 37) which are generally perpendicular thereto. Thus, the number of components to be assembled to produce an multistage dry vacuum pump is reduced, while providing satisfactory impermeability to outside atmosphere. | ||||||

Provided is a scroll fluid machine capable of effectively achieving performance of a tip seal installed in a tooth crest of a wall including an inclined portion. The inclined portion in which a distance between opposing surfaces of end plates facing each other gradually decreases from an outer peripheral side toward an inner peripheral side is provided. A tip seal (7) configured to make contact with a tooth base facing the tip seal (7) to perform sealing against fluid is provided in tip seal groove (3d) formed in a tooth crest of a wall (3b) corresponding to the inclined portion. In a stop state where a scroll (3) does not perform compression of fluid, an inclination height (Ls') of the tip seal (7) is smaller than an inclination height (Ls) of the wall (3b). |
