Abstract

A double circuit is proposed. The main circuit comprises a power unit (8), a main switch (1) connected in series, flow stabiliser (2) and hydraulic motor (9). The auxiliary circuit is also equipped with a power unit (8) connected in series with a multi-port valve (7), hydraulic cylinders and flow stabiliser connected to the power unit through the multi-port valve. In the proposed arrangement the main and auxiliary circuits are connected in parallel. The connection between the two circuits is provided with a pressure regulator and a check valve between two pressure gauges.
