Abstract
PURPOSE: To eliminate any link mechanism for switching by following one valve plate with the other valve plate manually switched by means of an oil path provided at a section where the two valve plates face each other.
CONSTITUTION: When a control lever 9 is turned clockwise, a valve plate 5 is rotated clockwise through a shaft 7 to displace a through hole of the valve plate 5. At this point, through holes 15 and 16 of the valve plate 5 are opened to a through hole 29 of a valve plate 6 while the through hole 15 is opened to a groove 28. A through hole 14 separates from a groove 32, and cut off the side of a tank to communicate a through hole 17 of the valve plate 5 to the groove of the valve plate 6. A through hole 19 of the valve plate 5 is opened to a groove 30 of a valve plate 6 to communicate a through hole 18 to a groove 32. Likewise, a through hole 22 of the valve plate 5 communicates to a groove 31 of the valve plate 6. With such an arrangement, a feed back arm 12 is fed back and hydraulically turned in the same direction as a control lever 9 thereby eliminating any link mechanism.
