VARIABLE-CAPACITY POSITIVE-DISPLACEMENT ROTARY BLADE MACHINE Russian patent published in 2002 - IPC

FIELD: variable-capacity pumps and motors. SUBSTANCE: machine has housing with intake and exhaust ports, rotor with one or several blades secured immovably on rotor whose axis of rotation coincides with geometric axis of inner cylindrical surface of housing; machine is also provided with contactor which consists of segments whose number is equal to number of blades; contactor is revolving about geometric axis under action of blades; geometric axis is eccentric relative to axis of rotor. Contactor is mounted for change of eccentricity of its geometric axis relative to axis of rotor in direction perpendicular to straight line between intake and exhaust ports. EFFECT: enhanced controllability of machine. 6 dwg
