<p>The control device (H) has pressure source tank assemblies (P,R) that are connected with hydraulic motor (M) through working lines (9,10). The piloted pressure holding valves (3,4) are respectively provided in working lines. The control pressure are supplied to piloted pressure holding valves from pressure controllers through control lines (24,25) based on position of a slider (31) in three-way valve (W). The control pressure in control lines are respectively controlled based on current supplied to magnets (18,20) of pressure controllers, when three-way valve is in neutral position.</p> |
