| 摘要 |
The present invention is related to a battery-operated liquid dispensing device comprising a valve which is operated by the trigger (4), and which comprises a valve body (22) with a resilient dome-shaped portion (24), which closes off the valve by being biased against the valve seat (25). By pulling the trigger (4), the dome-shaped portion (24) is pushed away from the seat (25), thereby creating a passage for the liquid to pass to a gear pump and nozzle (5). <IMAGE>
