Adjustable cooling pump group (1) for a cooling system of an internal combustion engine comprising a pump body (2), a rotor (3) and a shaft (5) connected to the rotor (3) suitable to move it in rotation around an axis (X-X). The pump group (1) comprises adjustment means (10) suitable for adjusting the quantity of liquid moved by the rotor (3) comprising: i) an obturator member (100) translatable along the axis (X-X), between a closed position, in which it surrounds the rotor (3) and obstructs the passage of cooling liquid, and an open position, translated in relation to the closed position, in which it permits the passage of liquid; ii) a cam element (200), housed in the pump body (2), in such a way that said translation of the obturation member (100) corresponds to a movement thereof. |
