| 摘要 |
<p>The invention relates to a spray head (100) for a liquid-product distributor, comprising an expulsion channel (1) ending in a spray hole (9) and a plug (10) which can be moved from a position in which it closes said hole (9) to a spray position. The plug (10) is moved elastically into its closing position and displaced towards the spray position by the pressure of the product. The spray head comprises a swirl chamber (20) of variable volume, the volume of said swirl chamber (20) being greatest when the plug (10) is in the spray position and substantially zero in the closed position. The invention is characterized in that the plug (10) comprises the spray hole (9) and swirl channels (30) which in the spray position link the expulsion channel (1) with the swirl chamber (20), where the volume and geometry of said channels (30) remains the same regardless of the position of the plug (10).</p> |
