Abstract

A pump (10, 10') for the circulation of a cooling fluid into a device such as an internal combustion engine or a fuel cell and provided with a magnetic-actuated flow regulator, said pump comprising an impeller (12) keyed to the end of a rotation shaft (14) connected to a means suitable for transmitting the rotary motion to the shaft itself and turnably arranged, by means of one or more bearings or brasses (20), relative to a container body (18) suitable for allowing the steady and safe fixing of the pump relative to the internal combustion engine or to the fuel cell, with said pump further comprising means for enabling/disabling the cooling fluid circulation with said magnetically-actuated means.
