A filter holder including a housing with a bottom and an aperture through the bottom; a valve with a stopper for opening and closing the aperture, the stopper supported by a pivoting arm and biased towards a closed position; a cam arranged between the bottom and the pivoting arm, and having a cam profile co-acting with the pivoting arm, and being biased towards a first position wherein the cam profile prevents closing of the stopper and having a second position wherein the cam profile allows closing of the stopper; a slider which co-acts with the cam to move the cam from the first position towards the second position. The slider is biased in an inactive position and is moved towards an active position by co-action with a locking ring whereto the filter holder is attached. The slider when moved towards the active position pushes the cam towards the second position.

1. A filter holder comprising: a filter housing provided with a bottom and a dispensing aperture through said bottom;first, second and third resilient members;a valve with a valve stopper, arranged for selectively opening and closing the dispensing aperture, the stopper being supported by a pivoting arm and resiliently biased by the first resilient member towards a closed position;a cam arranged between the bottom of the filter housing and the pivoting arm, the cam having a cam profile co-acting with the pivoting arm, the cam having at least a first position wherein the cam profile prevents closing movement of the valve stopper and a second position wherein the cam profile allows closing movement of the valve stopper, the cam being resiliently biased by the second resilient member towards the first position;a slider which co-acts with the cam to move the cam from the first position towards the second position;wherein the slider is resiliently biased by the third resilient member in an inactive position and is forced to move towards an active position by co-action with an element of a locking ring in response to the filter holder being attached; and wherein the slider is arranged for pushing the cam towards the second position when the slider is moved towards the active position. 2. The filter holder of claim 1, wherein the cam is pivotally connected to the bottom of the filter housing around a first pivoting axis oriented at about 90° with respect to a second pivoting axis of the pivoting arm which supports the valve stopper. 3. The filter holder of claim 2, wherein the first pivoting axis is approximately orthogonal to the bottom of the filter housing. 4. The filter holder of claim 1, wherein the filter housing is arranged in a seat integral with a filter-holder handle, and wherein the pivoting arm and the cam are arranged between the filter housing and a bottom wall of the seat. 5. The filter holder of claim 4, wherein the first resilient member, which resiliently biases the valve stopper towards the closed position, is arranged between the bottom of the seat and the valve stopper. 6. The filter holder of claim 1, further comprising a guide whereon the slider is movably mounted. 7. The filter holder of claim 4, wherein the filter housing comprises a cam support mounted on the bottom of the filter housing between the filter housing and the seat, and wherein the cam is pivotally connected to the cam support. 8. The filter holder of claim 7, wherein the third resilient member is arranged on the filter housing, for resiliently biasing the slider in the inactive position thereof and is located between the filter housing and the cam support. 9. The filter holder of claim 1, further comprising an actuating ring arranged around the filter housing and co-acting with the slider; wherein the actuating ring has a limited angular movement with respect to the filter housing and wherein the actuating ring co-acts with the locking ring whereto the filter holder is attached. 10. The filter holder of claim 9, further comprising a latch mechanism for selectively constraining the actuating ring to the slider, and releasing the slider from the actuating ring such that the slider can move angularly with respect to the actuating ring. 11. The filter holder of claim 10, wherein the latch mechanism comprises a first tooth constrained to the slider and a second tooth constrained to the actuating ring, the first tooth and the second tooth co-acting with one another to selectively constraining the slider to the actuating ring and releasing the slider and the actuating ring from one another. 12. The filter holder of claim 11, wherein the second tooth is radially outwardly movable in a release position, where the first tooth and the second tooth are disengaged from one another, when the actuating ring and the filter housing have achieved a mutual angular shift. 13. The filter holder of claim 11, wherein the second tooth engages a cam profile constrained to the filter housing, the cam profile being configured such that when the actuating ring and the filter housing are displaced one with respect to the other by a predetermined extent, the second tooth moves radially outwardly disengaging from the first tooth. 14. The filter holder of claim 11, wherein an angular shift of the actuating ring with respect to the filter housing causes a corresponding movement of the slider from the inactive position to the active position and therefore a movement of the cam from the first position to the second position, and wherein upon angular release of the slider from the actuating ring the slider is resiliently pushed back towards the inactive position. 15. A beverage producing machine including a filter holder according to claim 1 and a locking ring, the filter holder being engageable to and disengageble from said locking ring.
