MAGNETORHEOLOGICAL DRIVE FOR DIRECT ELECTROMAGNETIC CONTROL OF FLOW CHARACTERISTICS OF HYDRAULIC SYSTEM UPPER CIRCUIT OF SLIDE VALVE (VERSIONS) Russian patent published in 2017 - IPC F15B13/43 F15B21/06 

FIELD: machine engineering.

SUBSTANCE: magnetorheological drive of direct electromagnetic control of flow characteristics of hydraulic system upper circuit of the slide valve is designed for automatic control of the next hydraulic or pneumatic lower circuit of the system by means of the slide valve. The principle of direct electromagnetic control of the flow characteristics is based on magnetorheological effects of internal energy variation of magnetite particles and interaction energy of particles with each other in magnetic field, and the interaction of particles with magnetic field, and the laws of hydrodynamics.

EFFECT: increased speed, accuracy, reliability and durability of the upper circuit of the system, hence the hydraulic system as a whole due to application of hydraulic equipment with structure excluding movable mechanical elements.
