FIELD: machine building. ^ SUBSTANCE: air-hydraulic pulsed wrench contains casing with handle, located in it air actuator output shaft of which is connected to hydraulic pulsing booster implemented in the form of bushing with eccentricity, inside which it is located rotor with blade, rigidly connected to spindle of wrench. Internal surface of bushing allows compacting grips, forming with rotor and blade of high-pressure chamber and low-pressure chamber with openings for overflow of working liquid from high-pressure chamber into low-pressure chamber, constant magnet. Mentioned magnet is installed in bushing and creates effort pressing blade to internal surface of bushing at rotation of bushing relative to spindle. ^ EFFECT: reliability growth of wrenches. ^ 2 dwg |
