<p>Hydraulic device fitted with a regulable pump (2), said pump serving to create pressure chiefly in a control circuit (4) provided with a control valve (7), and fitted also with at least one further hydraulic working circuit (5) with a flow control valve (3), which secures priority in the control circuit, and with a reverse valve, which regulates the pump according to whether hydraulic pressure is greater in the control circuit or the working circuit. A regulating valve (25) is fitted to the feed pipe to the working circuit, said valve maintaining a balance between the working pressure in the working circuit (5), together with a switch spring (28), and the flow pressure in the feed pipe (16).</p> |
