Abstract
PURPOSE: To prevent a strong impulsive force, by slowly increasing oil pressure when it is applied to a PTO clutch cylinder.
CONSTITUTION: A pressure rise control valve 7 has a return port 10 for returning to a tank the pressurized oil introduced from an oil passage 9 and has a shutoff part 11 for hindering the return to the tank. The pressurized oil from the oil passage 9 is conduted to a return-hindering-side valve chamber 15 through a valve chamber 13 and an orifice 14 at the return side of a valve element 12. The valve element 12 is energized by a spring 16 so that the valve element is pushed and moved toward the valve chamber 13 to help the pressurized oil to act. The pressurized oil supplied to the valve chamber 15 is also conducted to a temporarily release valve 17 to push and move the valve rod 20 of the valve 17 against a spring 19 until the rod 20 comes into contact with a stopper 18. The position of the stopper 18 can be optionally changed by an adjusting screw 22 to control the rate of increase in the oil pressure.
