Embodiment Construction

[0015] With reference to the above figures, reference numeral 1 generally designates a pump set for a cooling system of an engine, preferably a cooling system of an internal combustion engine. Said pump unit 1 is of the duplex or hybrid type, as described below, comprising specific command means comprising electric drive means 5 and mechanical drive means 10 .

[0016] The pump unit 1 that is the object of the present invention comprises an impeller 3 rotatable about an axis X-X, such that the rotation of the impeller 3 corresponds to a predetermined amount of movement of the coolant in the circuit.

[0017] Preferably, the impeller 3 is of the radial type, that is to say it is such that the cooling liquid flow at the cooling inlet has a substantially axial general direction and the liquid flow at the outlet has a radial direction.

[0018] According to the invention, the pump unit 1 also comprises a shaft 2 extending in length along said axis X-X. An impeller 3 is operativel...

Abstract

A pump group (1) for a cooling system of an engine of a vehicle, of the dual type is provided. The pump group (1) comprises an impeller (3) mounted on a shaft (2) that is operable in rotation by an electric drive (5) and a mechanical drive (10). Said mechanical drive (10) comprises: a rotating member (11), that is operable in rotation by mechanical movement means comprised in the vehicle; a rotarydrum (12), operatively connected to the shaft (2); a centrifugal clutch device (15) comprising: m) a central body (151) integrally attached to the rotating member (11); n) a plurality of engagement elements (152) movably fixed on the central body (151) suitable to translate in a radial direction with respect to the axis (X-X) to engage the rotary drum (12).

Description

technical field [0001] The invention relates to a pump unit for a vehicle cooling system, preferably for cooling an engine, such as an internal combustion engine. In particular, the invention relates to a pump unit with double actuation means, ie comprising electric drive means and mechanical drive means. Background technique [0002] It is well known that during normal use of the engine it is appropriate to vary the intensity of the cooling effect. Intense cooling is required, for example, when the engine is running at full speed or in traction or on an uphill slope or in high ambient temperatures. In other conditions of use, on the other hand, cooling is not recommended, for example when the engine is started or when its use is over. [0003] Cooling pumps are known in the prior art, in which this need is met by having a double drive. In other words, cooling pumps are known in which the rotational speed of the impeller comprised therein is regulated by specific command ...
