のねじ状軸流回転ピストン。[Claims for Utility Model Registration] (1) A threaded axial flow rotary piston consisting of a central threaded rotary piston and two pairs of oppositely arranged threaded rotary pistons meshing with the central threaded rotary piston,
Each of the screw-shaped rotary pistons is formed in the respective casing so that each tooth portion in the axial direction is twisted in a spiral shape by at least one lead (pitch) to the right and left without changing the cross-sectional shape perpendicular to the axis. , and a threaded shaft characterized in that only the lead (pitch) of each threaded wire is gradually changed as much as possible, and the volume closed along the threaded line within the casing is formed so as to gradually change. Flow rotating piston. (2) The leads of the threaded wires of the central screw-shaped rotary piston and the two sets of oppositely arranged screw-shaped rotary pitons that mesh with the central screw-shaped rotary piston are connected to the rotation angle Θ of the central screw-shaped rotary piston and the pitch. By forming the relationship = kΘ 2 (k: constant), the volume closed along the thread line within the casing changes linearly with respect to the rotation angle θ. A threaded axial flow rotary piston according to claim 1, which is characterized by:
