Valvular disposition for the activation of hydraulic cats, which is applicable to cats that are conventionally constituted by the association of two cylinders of different capacity whose pistons work in opposite directions, the smallest being capable of sucking from a reservoir full of hydraulic fluid and of driving the quantity of fluid drawn up to the cylinder of greater size, it is essentially characterized by comprising four valves, located two in the communication conduit of the small cylinder in the reservoir of hydraulic fluid and two others in the communication conduit between the two cylinders, of which the first ones open when the piston of the aforementioned, small cylinder performs the aspiration, while the second ones open when the piston carries out the impulsion.
