HYDRAULIC CLUTCH WITH ROTARY VANE PUMP Russian patent published in 1999 - IPC

FIELD: mechanical engineering. SUBSTANCE: hydraulic clutch includes housing and rotor with spring-loaded blades coaxially relative to housing forming the high-pressure and low-pressure working fluid zones between housing and rotor. Clutch is also provided with spool valve having rod and piston. Spool valve is mounted for separation of high-pressure and low-pressure zones. Clutch is provided with mechanism for retraction and fixation of blades of rotor in inoperative position and cylindrical member located at eccentricity relative to rotor for radial motion between housing and rotor. Rotor blades are in contact with above-mentioned cylindrical member. mechanism for retraction and fixation of rotor blades in inoperative position is made in form of hydraulic drive. EFFECT: enhanced operational reliability; increased service life of clutch; improved mass and dimensional characteristics; possibility to change sense of shaft rotation. 3 dwg
