【発明の名称】比例弁制御装置
Document Type and Number:
Japanese Patent JP2722058
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To cope by a common constitution with a change in the amplitude of the maximum driving current which can be supplied to a proportional valve. SOLUTION: The power source voltage Vp' of a proportional valve control circuit 20 for generating the proportional valve driving current at the time according to a current control signal Vi can be altered by a variable switching power source 50. The power source 50 alters the power source voltage Vp' according to the value indicated by the power source voltage specified signal Pv generated from a microcomputer 10, and applies it to the circuit 20.
