CONTROLLER FOR LIQUID PRESSURE BUFFER OF VARIABLE DAMPING FORCE TYPE

摘要

PURPOSE:To decide whether a contactor is contacting correctly with each conductive pattern and providing regular rotary angle position detecting signal by considering the shape of conductive pattern in rotary angle position detector. CONSTITUTION:In a rotary angle position detector to be employed in buffer controller, a contactor 34 rotatable synchronously with motor is slided against first and second conductive patterns 31A, 32A formed in rotary angle regions (a)-(c) of motor splitted into three. Here first conductive pattern 31A is formed across the starting position a1 in first rotary angle region (a) to the end position (b2) of second rotary angle region (b). While second conductive pattern 32A is formed across the start position (b1) of second rotary region (b) to the end position (c2) of third rotary angle region (c). Then a circular common conductive pattern 33A is formed between both patterns 31A, 32A.
