摘要

The fuel dispenser (2) has a pump and a through-flow meter, at least one counter (3) and an indicator (4). The fuel flows through one or more hoses (5). At least one hose dispenses at least two types of fuel via a gun (6) connected to the hose. The hose is made of flexible material, especially rubber and contains at least two separate flow ducts separated by radial bridge pieces. At least one duct is for returning gas. Each flow duct has a constant cross-section although the cross-sectional shapes and surfaces of individual ducts may vary.
