摘要

Hydraulic steering device for a piston capable of being driven alternately in both directions at high number of strokes, which at one end hits against a stop to produce a job, characterized by that for the inversion of the plunger, in order to actuate it alternatively in either direction, it comprises a main slide or valves, and for the initiation of the actuation of said slide or of said valves comprises a pre-steering slide that is operated at the end of each stroke, by means of mechanical transmission elements, by its own piston, reversing the main slide or the valves for the idle stroke of the plunger without any delay, while the inversion for the working stroke of the plunger is carried out with delay, so that the inversion of the plunger itself is it starts before the beating, but it is not done until after the beating.
