发明名称 OIL PRESSURE PUMP CONTROLLER
摘要 PURPOSE:To provide such an oil prossure pump controller that can provide the maximum drive speed suited to respective hydraulic actuators. CONSTITUTION:The swash plate 1a of an oil pressure pump 1 is controlled by a regulator comprising an oil pressure cylinder 2 and spools 3, 4. When a boom cylinder 6 is operated, the operation quantity is detected by a pressure sensor 18 (19) so as to by inputted into a controller 22. Similarly, when a rotary motor 8 is operated, the operation quantity is detected by a pressure sensor 20 (21) so as to be inputted into the controlling 22. Function generators for extracting tilt rotation amount according to each operation quantity are provided for every hydraulic actuator in the controller 22 and the maximum value of the tilt rotation amount is set to an optimum value obtained by taking the mechanism, etc., of respective hydraulic actuators into consideration.
