Passively controlled automatic valve, especially a pump valve |
| 摘要 |
The valve body (9) is designed in such a way, being provided, for example, with helical ribs or grooves (14, 15), that, during the opening stroke, it is turned by the flow of fluid passing through the valve and, accordingly, sets down on the associated seat in a different rotational position during the following closing stroke. <IMAGE>
