Abstract
PURPOSE: To make setting of high injection speed sure and easy by providing a stop valve for improving rise characteristics, and a throttle valve for improving handle opening and flow rate linearity in series in a communicating passage from an accumulator to an injection cylinder.
CONSTITUTION: First, a check valve 9 is closed and low speed injection is carried out without emitting the working fluid from an accumulator 8 to the injection cylinder side. Thence, a 4-way changeover valve 13 is changed over by the signal of a limit switch to communicate a port P and a port B. When a pilot check valve 15 opens, the rear end part of the check valve 9 connects to a tank 16. The accumulator pressure is acting upon the surface 9a of the check valve 9, and since a beveled part 9b is provided in the leading end part of the valve 9, the valve 9 opens instandaneously. On the other hand, a throttle valve 11 for flow rate control is beforehand held open at a prescribed opening, and therefore the working fluid from the accumulator 8 is conducted immediately to the injection cylinder 7 side at the flow rate corresponding to said opening, and high-speed injection is carried in an extremely short time.
