ROLLER-BLADE HYDRAULIC MACHINE Russian patent published in 2006 - IPC F01C1/14 

FIELD: general engineering.

SUBSTANCE: invention relates to roller-blade hydraulic machines operating as pump or hydraulic motor. In proposed roller-blade hydraulic machine blades of rotor are displaced relative to each other through angle equal to 60°, section of angular contact interaction of inner surface of stator housing with blades of rotor has length found from equation L=2/3·π(R+δ₁) where R is radius of rotation of rotor blades; δ₁ is value of guaranteed radial clearance between blades of rotor and inner surface of stator housing. At implementing the invention, optimum in parameters premeditated compression space is formed in stator housing which contributes to uniformity of passing of working medium from suction space into delivery space when hydraulic machine operates as pump, or uniformity of rotation of output shaft of rotor, when hydraulic machine operates as hydraulic motor.

EFFECT: improved reliability of operation.
