Abstract (en)

Cooling fluid recirculating pump, comprising a fixed pump body (11) carrying a driven shaft (2) for actuating the impeller (1) of the pump and at least one friction coupling (30;130) arranged between the movement generating means (21) and the driven shaft (2) and comprising at least on fixed electromagnet (32) and at least one armature (33;133) which is mounted axially movable on a sleeve (35) integral with the shaft (2), axially thrusting resilient means (34;134) acting on the armature (33), said electromagnet (32) being axially arranged on the opposite side to the armature (33;133) in an axially outer position with respect to the movement generating means (21,21a).
