Abstract: In a dry vacuum pump including: a casing having an inner cylinder (1a) communicating with an inlet (6) and an outlet (7) of the pump; shafts (15b) supported by the casing; spiral toothlike parts (15a) formed on the shaft (15b); a plurality of screw rotors (15), each of which includes the shaft (15b) and the spiral toothlike parts (15a) received in the inner cylinder (1a) intermeshing with each other; timing gears (16, 19), each of which is attached to the respective shafts (15b) of the screw rotors (15) and intermeshes with each other; and locking mechanisms (17), each of which for fixing the timing gear (16, 19) to the shaft (15b), both of the shaft (15b) and the toothlike part (15a) made of spheroidal graphite cast iron containing 20 to 30 wt % of nickel are casted integrally. With the construction described above, a problem such that a degree of vacuum deteriorates due to peeling of a resin coating is solved as to a dry vacuum pump pumping corrosive gas. A tapered face of 1/(20L) is formed with respect to the toothlike part (15a) so that an outer diameter of the toothlike part (15a) is shortened from the center of the toothlike part (15a) to the outlet side of the fluid, L being a length of the toothlike part, and a aground finish-surface is formed with respect to the toothlike part (15a) so that a diameter of the toothlike part (15a) is shortened by 3/100 to 4/100 mm from a position, where is about 10 mm offset toward the inlet side from the center of the toothlike part (15a), to the outlet side. With this construction, a seizure of the toothlike part (15a) is prevented from occurring. Nitrogen gas is supplied into the casing and an outlet path (20) connecting the outlet (7) with a scrubber (11) is a straight pipe, in which a silencer is removed. With this construction, heat capacity of the gas discharged from the outlet (7) is increased and reaction products are prevented from depositing in the outlet path (20).

Abstract: A scroll type apparatus for fluid displacement is disclosed. In one embodiment, the apparatus includes an adjustment mechanism capable of being adjusted after assembly of the apparatus to close an axial gap between scroll members and account for manufacturing tolerances in apparatus components. In another embodiment, the apparatus includes an orbital scroll of two portions, with a supporting portion surrounding an eccentric bearing of higher density than that of a scroll portion. The center of mass of the orbital scroll is thus moved towards the eccentric bearing to reduce torquing of the scroll as it orbits. In a further embodiment, the apparatus includes an orbital scroll having two portions, a supporting portion surrounding an eccentric bearing having a lower coefficient of thermal expansion than that of a scroll portion, to reduce thermal expansion of the supporting portion, reducing misalignment of the eccentric orbital scroll on the bearing.
