エレクトロハイドロリック式の調整装置
Document Type and Number:
Japanese Patent JP4283958
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To avoid a reduction characteristic line of an adjusting device from drastically falling to zero carrier at the same time as it reaches a pressure target value and to eliminate a defect caused by it. SOLUTION: This adjusting device 14 has a signal feedback line 43 connecting a position adjusting device 30 to a pressure adjusting device 34 to generate a reduction characteristic line 60b having a slope having a value being smaller than zero at least in the area of a pressure target value 62, the signal feedback line 42 respectively has at least one amplifier element 40 and one subtraction element 38, and the element 38 calculates a corrected control value for the device 34 from the difference between an amplified position signal of a control device 18a and an externally suppliable pressure target value.
