Abstract (en)

A variable output pump device, comprising a movable component capable of displacing a liquid fluid, said movable component being driven at constant speed by a motor, a similar actuating means or a means of transmitting movement, said movable component being mounted in a chamber of a housing comprising a supply passage or orifice and an outlet passage, the output of the pump device being variable according to the temperature of the liquid fluid aspirated and delivered by said device, at least within a certain temperature range. <??>The pump device (1) also comprises a heat-sensitive component (8) mounted in the supply passage or orifice (6) or in the outlet passage (7), the apparent surface in a projection plane perpendicular to the direction of the fluid flow of said heat-sensitive component (8) being a function of the temperature of said fluid with which it is in direct contact. <IMAGE>
