<p>The reflector has a tank (R) which is connected to the hydraulic cylinder-free switching valve (36). The switching valve for few interconnected 5/2-way valve and 3/2-way valves (38,39), each in working lines (17,18,20,21) is arranged between the hydraulic cylinder with one-directional valves (43,44) connecting the passage switching position and separating hydraulic cylinder from directional valve without leakage. A hydraulic cylinder connected to the tank is operable in activation switch position, so that the 3/2-way valves share a common actuator (37) for one switching direction.</p> |
