ELECTROHYDRAULIC MOTOR Russian patent published in 1997 - IPC

FIELD: mechanical engineering; transport; high voltage discharge in liquid medium with subsequent conversion of this energy into rotation energy. SUBSTANCE: electrohydraulic motor has hydraulic cylinder with rotor and end face covers with channels to feed and let outworking medium, and high pressure pulse shaper. High pressure pulse shaper has two chambers. High pressure discharge chamber with flexibly deformable walls and electrodes installed for interaction is placed between chambers of pulse shaper. Hydraulic cylinder has support partitions mated with its inner surface. These partitions divide hydraulic cylinder into two working chambers. Compassing members are mounted on rotor in each chamber. Compassing members are made in form of sectors with shaped slots at rotor side filled with equal-size metal ball adjoining each other over entire length of rotor. Shock absorbing arrangement, for instance, pull-back spring, is installed between partitions and compassing members of rotor. EFFECT: enlarged operating capabilities. 2 cl, 2 dwg
