IMPROVEMENTS TO BRAKING THE WAY WITH RECOVERY

摘要

Improvements introduced in devices unidirectional regenerative braking comprising a sliding plunger axially inteior a brake cylinder characterized in that said piston is fixed to the end of a stem on the other protrudes exteriro device which is connected to means external coupling devices is slow the rod comprises a portion of the threaded length with a thread long enough step to provide reversibility system cooperating with a similar thread provided in an opening of a part is provided fixed in relation the cylinder and a second portion of its length by a helical spring surro axial action to push the piston and rod assembly in the direction in which the latter is the braking resistor.
