Patent number: 9341103Abstract: The present invention refers to a device (1) for water circulation in a cooling circuit of an internal combustion engine (3). The device comprises a pump and a suction chamber (8) which develop in a circular way around the axis of the pump impeller. The device comprises also a water manifold (50) that can be connected to the outlet of a radiator (40) of said cooling circuit. The device comprises a first duct (5) connected to the manifold and a first opening (5?) which defines an axial inlet for said first flow in said chamber (8). The device comprises also a second duct (6) connected to the manifold (50) and to the suction chamber (8?) by means of a second opening (6?). The latter defines a tangential intake for water, so that it is subject to a rotation around the axis of the impeller. The device further comprises flow rate partition means (9) suitable to vary the flow rate of the water circulating in both ducts (5,6) as a function of the operating conditions of said engine.Type: GrantFiled: December 18, 2012Date of Patent: May 17, 2016Assignee: FPT INDUSTRIAL S.P.A.Inventor: Clino D'Epiro
