GRAVITY HYDRAULIC MACHINE Russian patent published in 1998 - IPC

FIELD: mechanical engineering. SUBSTANCE: gravity hydraulic machine has frame with two working sections installed coaxially relative to each other on machine frame. Each working section has housing with working medium inlet and outlet channels. Stator installed with clearance inside housing has circular case mated through outer surface with roller wheels coupled with outer drive arrangement and circular frame. Circular high pressure chamber with radial slots is located in clearance on outer surface of circular frame. Chamber is filled with high pressure liquid or gas and in provided with movable radial blades installed in radial slots. Blades form working sections coupled through radial channels with working medium inlet and outlet channels. Housing has rotor with movable frame accommodating movable device and eccentric ball with movable shaft mated with movable device. Hydraulic machine has magnetic control system with electromagnets on stator and electromagnets with control windings on rotor. Collectors for energizing electromagnet control windings from external power source are installed on movable frame rotation shaft. EFFECT: enlarged operating capabilities. 4 cl, 3 dwg
