  • Control Of Positive-Displacement Pumps (AREA)

Abstract

PURPOSE: To give the equivalent control function to an electricity-oil servo valve to an electricity-oil servo mechanism for an inclination-angle controller of an oil pump motor by using a two-position control valve without using any electricity-oil servo valve.
CONSTITUTION: When an input signal is given from an input terminal 1a, the output is partly used for feedback by a deviation amplifier 1, and on the other hand, a deviation output voltage is taken out as a deviation amplified in a deviation amplifier 1 to be compared with the command signal from a command input 1. The value of this deviation signal is compared with the peak value of the saw tooth voltage taken out in adaptation to each servo mechanism by giving the saw tooth voltage generated in a saw tooth like signal generator 2 to a proportional band setter 3 in comparators 4a and 4b, and on/off widths of output transistors 5a and 5b are controlled in proportion to the value of the peak value for controlling an electricity-oil servo mechanism to control the inclination angle of a pump motor.
