ROTARY MACHINE Russian patent published in 1997 - IPC

FIELD: mechanical engineering; pumps and engines. SUBSTANCE: rotary machine has housing with cylindrical bore and working medium inlet and outlet channels, stator rings installed coaxially in housing. Rotor with diametrically profiled slots accommodating rods with separating plates on ends is also installed in housing. Plates can move radially in rotor slots to form working chambers in stator rings. Both ends of each rod are rigidly connected with adjacent plates. Inner surface of stator ring is made in form of polygon coaxial with stator ring outer surface with number of working faces equal to number of plates. Length of faces is made to satisfy the condition L>2E+T, where L - length of working face of polygon; E - eccentricity of rotor setting relative to stator ring; T - width of contact surface of plate radial end. Contact surface of radial end of plate is made at right angle to rod axis. Width of contact surface of plate radial end exceeds thickness of plate. Longitudinal slot is made in central portion of each contact surface of plate. Resilient sealing member in form of plate bent in cross section to arc of circumference is placed in longitudinal slot. Rotor and stator ring are mechanically connected by gear train with gear ratio 1:1. EFFECT: enlarged operating capabilities. 5 cl, 4 dwg
