Controlling device for adjusting circulation of gaseous or liquid fluid through opening or passage through pipe by comparing indicated positions of movable element obtained from reference signal and from signal delivered by sensor

摘要

A control device (5) indexes during consecutive running of an operating cycle. Open/closed state of an adjusting component (1'') is set under a control of the reference signal (SIGN). The control signal (IN) is applied according to the result of comparing the indicated positions of the movable element (1''), obtained firstly from the SIGN and secondly from a signal (OUT) delivered by a sensing device (4). Independent claims are included for: (a) an adjusting device (b) a circuit for circulating a fluid in motor vehicle
