ABSTRACT:
A machine for the compression or expansion of a fluid comprising a multi-thread screw having opposite low and high pressure ends, the screw being mountable for rotation about an axis to cooperate in substantially fluid-tight manner in a cylindrical bore of a stationary casing, at least one pinion having teeth disposed for meshing engagement with the screw threads and rotatable about an axis transverse with respect to the axis of screw rotation. The screw is carried by a shaft supported by two sets of bearings respectively disposed on each end of the screw. The casing bore is open at both ends and the high pressure end of the casing includes a hoop having an internal bore diameter substantially smaller than the diameter of the bore. The low pressure end of the casing bore is of a diameter at least equal to the diameter of the screw for introduction of the screw into the casing bore during assembly of the screw and casing.
