Anti cavitation device for a hydraulic cylinder
Anti-cavitation device for a hydraulic cylinder, comprising: a first conduit (2) predisposed to connect a first chamber (C1) of a cylinder (C) with a distributor (D); a second conduit (3), predisposed to connect a second chamber (C2) of the cylinder (C) with the distributor (D); a control valve (4), arranged along the first conduit (2), which is predisposed to allow the flow of fluid from the distributor (D) towards the first chamber (C1) and to allow the flow of fluid from the first chamber (C1) towards the distributor (D) only if it is supplied with a pilot pressure over a minimum value; a third conduit (5), which connects the second conduit (3) with a tract of the first conduit (2) between the control valve (4) and the distributor (D); a shut-off valve (6), arranged along the third conduit (5), which is mobile, following a command, between an open configuration, wherein it allows the flow along the third conduit (5), and a closed configuration, wherein it prevents the flow along the third conduit (5); the activation valve (6) is configured to receive an opening command only if the control valve (4) is supplied with the pilot pressure.
