Abstract

The invention relates to a railroad switch operating mechanism wherein there are a reversible electric motor, a volumetric pump coupled thereto a double acting hydraulic jack the action of which is transmitted to the operating rod of the switch by means of a bell crank axially secured in a sealed block containing oil which serves as lubricant and a fluid for the operation of the jack. The combined pump-jack-block forming a closed hydraulic circuit.
