Control device for slanting plate type variable capacity pump |
摘要 |
A control device is herein disclosed which comprises a drive piston 12p for changing the position of a slanting plate in a variable capacity pump 11, an electromagnetic proportional valve 13 for driving the drive piston, and a position detector 14 for detecting a position of the slanting plate. The control device performs a flow rate control of operating oil by controlling the electromagnetic proportional valve in accordance with a difference between a flow rate instruction value Fr for the operating oil and a position detection value from the position detector so as to change the position of the slanting plate. The control device further includes a pressure detector 18 for detecting a pressure of the operating oil supplied to an injection cylinder 10, and correcting means for correcting the flow rate instruction value on the basis of a pressure detection value from the pressure detector to output a corrected flow rate instruction value.
