Abstract

Improvements in fluid regulation systems of internal combustión engines of the type comprising a detector device for detecting the relationship between an existing condition of the fluid and a demand signal, and a regulation device controlled by an output signal of the detector device, to regulate the condition of the fluid if it deviates from a predetermined relation with the demand signal, in order to re-establish in this way said predetermined relation, characterized in that the means detecting device is provided to derive a fluid control pressure indicative of the relationship between an existing condition of the fluid or a demand signal; a control chamber in which the fluid control pressure acts in position at a thrust pressure on a mobile control element, whose control element is part of a transducer, whereby the sensing device continuously produces an electrical signal of representative output of the instantaneous position of the control element, and the regulation device is designed to be controlled by said electrical output signal in order to regulate the existing condition of the fluid in such a way as to maintain the fluid control pressure practically at a constant value.
