专利汇可以提供METHOD AND APPARATUS专利检索,专利查询,专利分析的服务。并且In a fuel vapour recovery system, fuel vapour is drawn off and converted to liquid fuel. The system comprises a compressor (34), individually closable inlets (30,30a,30b...) for the fuel vapour and leading to an inlet duct (12) of the compressor (34), a return duct by way of which an outlet of the compressor (34) communicates with the inlet duct (12), and a control device (66) which controls communication between that outlet and the inlet duct (12) via the return duct in dependence upon the number of the inlets (30,30a,30b...) which is open. The system further comprises a tank (52), a first sensor (82) which serves to detect when liquid water in the tank (52) attains a predetermined height in the tank, a second sensor (80) which serves to detect when liquid fuel in the tank (52) attains a higher, predetermined height in the tank, a first device (58) responsive to the first sensor (82) and serving to cause removal of at least part of the liquid water from the tank when the liquid water attains the first-mentioned predetermined height, and a second device (58) responsive to the second sensor (80) and serving to cause removal of at least part of the liquid fuel from the tank (52) when the liquid fuel attains the higher, predetermined height.,下面是METHOD AND APPARATUS专利的具体信息内容。
