摘要

A vapour recirculating device for a fuel filling installation, said fuel being liquid and highly volatile, such as petrol, and said device comprising a vapour pumping means (11) for recirculating fuel vapour. Said vapour pumping means (11) has at least two vapour pumps (10) with separate inlets (9) and outlets (9) arranged in a pump housing component. The vapour pumps (10) are interconnected by means of a common drive shaft (14) and have an overflow valve (21) to allow common operation. <IMAGE>
