POWER ACCUMULATOR Russian patent published in 2010 - IPC H01H9/00 H01F29/04 

FIELD: electrical engineering.

SUBSTANCE: invention relates to power accumulator for step switch operated at load with lengthwise-travel winding slides and lengthwise-travel jumping slides which, when unlocked, repeat the motion of winding slides and convert their translation into rotation of output shaft that actuates loaded step switch. Said jumping slides accommodate two guided rollers arranged in particular-geometry link. Note here that during first part of every stroke of jumping slides only one roller in guided in said link with geometrical tangenting (jointing), while, during second part of stroke, second roller moving free is guided in said link with geometric tangenting, while roller guided previously in said link moves free. Finally, during third part of stroke, roller moves again with geometrical tangenting in said link.

EFFECT: possibility to vary torque at output shaft and to produce high torque that allows reliable reach of final position and repeated interlocking of power accumulator.
