Abstract

Hydraulic system of low presid, that buy of a motor whose working means is controlled through a first and a second cases of that one by means of an activating valve, to move said motor in a first and a second directions, respectively, against a force external and with the collaboration of it; a discharge conduit associated with a discharge valve controlled by a pressurized medium, in which a supply side of said conduit is coupled to the first mentioned passage, while an ejection side is coupled to an expulsion side of said activator valve, characterized in that a control conduit (38) of said discharge valve (28) passes through a control valve (41) by virtue of which the control pressure from the second step (22) can be freely transmitted. Through said control conduit to an energy control chamber (35) of said discharge valve, the control valve (41) having a slider (42) which is driven at its end by the pressure from the first step ( 19, 20, 21) against an adjustable counterforce acting against said slider in the opposite direction, said slider forming an open connection between the first mentioned step (19, 20, 21) and the second step (22) in the open assumption. Away from the control conduit (38) and thus exerting an intermediate pressure on the force control chamber (35) which cant the opening of the said discharge valve for a full pass, the first step cited on the ejection side (29) of the activating valve (13) after an increase in pressure in a branched circuit (46) that connects said control valve to the supply side (26) of said conduit, at a higher level than the aforementioned adjustable counterforce, thus obtaining a limitation of pressure in the first step mentioned.
