Abstract

It comprises a pair of hydraulic cylinders 1, 2 arranged in parallel, machined in a common casing 3, the pistons (plungers) 4, 5 of which are each integral with racks 6, 7 which transmit the movement to a pinion 8. The cylinders 1, 2 comprise a common cylinder casing 9 provided with orifices 10, 11 for conveying the hydraulic fluid. The mechanism of the invention comprises a damping device associated with a piston 4, 5 which consists of a pin integral with the piston and provided with a helical groove of decreasing width in the direction of advance. By virtue of the arrangement of the cylinders, the dimensions of the mechanism are made smaller and the pinion works in a more regular fashion. Tubes for connection between cylinders are also eliminated. It applies especially to the actuation of automatic doors.
