Abstract

An apparatus for compensating pressure inside a circuit travelled by a fluid, in particular a coolant fluid, comprises a chamber (2; 202) flowingly connected to said circuit by means of an inlet (30; 230) and an outlet (31; 231), said chamber (2; 202) comprising wall means (3; 203) that is movable for varying a volume of said chamber (2; 202) so as to compensate for a variation in said pressure in said circuit, said apparatus comprising a further chamber (22; 222) flowingly connected to said circuit, said further chamber (22; 222) being provided with transparent wall means (23; 223) to enable the possible presence of air inside said circuit to be visually checked and provided with closing means (24; 224) that is openable so as to enable said air to exit said circuit.
