| 摘要 |
The present invention relates to a device for controlling the recovery of vapour at stations for the dispensing of liquid fuels, e.g. petrol of various grades, from a first tank or container to a second tank or container by the intermediary of a pump and a line and/or hose with a nozzle, e.g. a pistol valve, and with a channel and/or hose for the recovery and recycling of vapour from the second tank or container to the first tank or container, or some other auxiliary aid for managing the vapour, a valve being disposed in the line or the hose between the pump and the nozzle and including at least one through flow channel (14-19) for the fuel and at least one through flow channel (13) for the vapour which is to be recovered and recycled the valve having a valve cone (12) and a valve seat (11) and the valve cone (12) being switchable against the action of a spring (9) from closure abutment against the valve seat corresponding to the fuel flow occuring in the through flow channel (14-19) so that vapour is recovered and recycled via the valve seat (11) in proportion to the fuel flow.
