METHOD OF AND DEVICE FOR CREATING UNIFORM FLOW OF WORKING LIQUID Russian patent published in 2007 - IPC F04C2/344 F04C14/00 

FIELD: mechanical engineering.

SUBSTANCE: invention can be used to reduce level of vibrations and noise caused by fluctuations of liquid flow in operation of rotary guide-vane-machines. Method includes rotation of rotor of rotary guided-vane machine, filling of machine intake space with working liquid at intake pressure, separation of working liquid is transfer spaces separated from outlet space with outlet pressure non-equal to intake pressure by gates from intake space, transfer of working liquid is transfer spaces to outlet space, connection of transfer spaces with outlet space and forming working liquid into outlet space of machine. Each transfer space includes intervene space which is separated from intake and outlets spaces within the limits of preset range of rotor turning angles, and at least one variable-capacity power chamber made in rotor and communicating with intervene space of said transfer space. In process of transfer, volumes of transfer spaces and working liquid pressure in said spaces are changed by changing capacities of said power chambers to equalize pressure with outlet pressure to moment of connection of said transfer spaces with outlet space.

EFFECT: reduced level of liquid flow fluctuations.
