PURPOSE:To simplify a link mechanism which is therefore hard to be failed, by connecting a valve plunger in a control valve directly with a control cable connected to a dump control lever. CONSTITUTION:Casings 4, 5, 6 respective for a PTO1, an oil pump 2 and a control valve 3, are formed separately from each other, but are integrally incorporated with each other by means of a bolt 7. A plunger 20 is born in the casing 6 in a valve 3, and a control link 25 which is rotatably supported by a support shaft 24 in a proximity position above a pump 2, has a plunger coupling arm 27 and a cable coupling arm 28, and a coupling pin 32 of the plunger 20 is fitted into the arm 27. Further, one end of a control cable 33 is connected to the arm 28, and the other end of the cable 33 is connected to a dump control lever. |
