Device for pressing the coffee powder within the filter holder |
| 摘要 |
A device for pressing coffee powder, characterised by comprising:;a lowerly open first hollow cylinder body (8),;a presser element (10) housed within said first hollow cylindrical body (8) and consisting of a lowerly open but upperly closed second hollow cylinder body, its lower edge being provided with an annular flange (28) of outer diameter D1,;a pressing member (60) slidable vertically within said second hollow cylindrical body, the head (34) of which, of diameter D2, where D2<D1, emerges from the base aperture of said second hollow cylindrical body,;elastic means (44) housed within said presser element (10) and acting on said pressing member (60) to maintain the pressing head (34) spaced from the annular flange (28) when the pressing device is not in use, said elastic means (44) being subjected to compression during coffee pressing by the pressing head (34),;means (18) for causing said presser element (10) to descend vertically relative to said first hollow cylindrical body (8),;the pressing member (60) being provided with a pin (38) transverse to the longitudinal axis of the presser element (10) and provided at its ends with at least one roller (40) guided along a helical groove (42) provided in the lateral surface of the presser element (10). |

1. A device for pressing coffee powder, characterised by comprising:
a lowerly open first hollow cylinder body (8), a presser element (10) housed within said first hollow cylindrical body (8) and consisting of a lowerly open but upperly closed second hollow cylinder body, its lower edge being provided with an annular flange (28) of outer diameter D1, a pressing member (60) slidable vertically within said second hollow cylindrical body, the head (34) of which, of diameter D2, where D2<D1, emerges from the base aperture of said second hollow cylindrical body, elastic means (44) housed within said presser element (10) and acting on said pressing member (60) to maintain the pressing head (34) spaced from the annular flange (28) when the pressing device is not in use, said elastic means (44) being subjected to compression during coffee pressing by the pressing head (34), means (18) for causing said presser element (10) to descend vertically relative to said first hollow cylindrical body (8), the pressing member (60) being provided with a pin (38) transverse to the longitudinal axis of the presser element (10) and provided at its ends with at least one roller (40) guided along a helical groove (42) provided in the lateral surface of the presser element (10). |
