Claim:
An apparatus for degassing oil in an oil system, the apparatus ( 20 ) comprising: a room ( 30 ) for receiving oil that is to be subjected to degassing; an inlet ( 31 ) for feeding oil into the room ( 30 ); an outlet ( 32 ) for feeding oil out of the room ( 30 ); a suction arrangement ( 40 ) connected to said outlet ( 32 ) for sucking out oil from the room ( 30 ) via the outlet; a non-return valve ( 33 ), which is connected to the upper part of the room ( 30 ) and which is arranged to allow gases and water vapour to flow out of the room ( 30 ) and thereby allow an underpressure that promotes separation of gas from the oil to be generated in the room ( 30 ); and a regulating device ( 50 ) for regulating the feeding of oil into the room ( 30 ) via said inlet ( 31 ), characterized in: that said room ( 30 ) comprises a first chamber ( 30 a ) and a second chamber ( 30 b ), which is connected to the first chamber, smaller than the first chamber and arranged above the first chamber, said inlet ( 31 ) and outlet ( 32 ) being arranged in the first chamber ( 30 a ) and the non-return valve ( 33 ) being connected to the second chamber ( 30 b ); that the regulating device ( 50 ) comprises a float ( 51 ) and a valve member ( 52 ) actuated by the float; that the float ( 51 ) has a lower section ( 51 a ) located in the first chamber ( 30 a ) and an upper section ( 51 b ) extending into the second chamber ( 30 b ), the upper section ( 51 b ) of the float ( 51 ) delimiting a flow passage ( 63 ; 64 ) extending between the first chamber ( 30 a ) and the second chamber ( 30 b ); and that the valve member ( 52 ) is arranged to open said inlet ( 31 ) when the float ( 51 ) assumes a lower first position in the room ( 30 ) and close said inlet ( 31 ) when the float assumes an upper second position in the room ( 30 ).
