- Each pin 25 engages and slides transversely along a respective track 27 formed along a first arm 28 of a respective rocker arm 29, which is located between longitudinal walls 9 and 10, and is connected to relative longitudinal wall 9, 10 to rotate with respect to it about a fixed axis 30 perpendicular to axis 8, parallel to axis 26, and located between plate 18 and transverse wall 12.
- Each track 27 extends in a respective plane perpendicular to axis 30, and comprises two branches 31 and 32 connected to form a V with its concavity facing substantially upwards, and of which branch 32, facing axis 30, is longer than branch 31 and has an axis 33 perpendicular to axis 30.
- Each pin 25 moves along respective track 27 from a rest position ( Figure 3) , in which plate 18 is in the withdrawn rest position contacting open end 15 of outer body 14, pin 25 occupies one end of respective track 27, and both branches 31 and 32 are located below the plane defined by axes 8 and 30.
- each pin 25 from the rest position described causes relative rocker arm 29 to rotate (clockwise in Figures 3 to 5) from a start position ( Figure 3) - in which axis 33 and the axis 33 of the other rocker arm 29 define a plane, which intersects, along axis 30, the plane defined by axes 8 and 30, and slopes downwards from axis 30 - to an end position ( Figure 4) - assumed upon pin 25 engaging branch 32 of respective track 27, and in which the plane defined by axes 33 is coplanar with the plane defined by axes 8 and 30.

- the end of each rod 44 facing transverse wall 11 is fitted with a sleeve 45, which clicks onto a respective bracket 46 projecting upwards from the top edge of relative longitudinal wall 9, 10, alongside outer body 14 of hydraulic cylinder 13.
- the end of each rod 44 facing transverse wall 12 engages a hole formed in a respective bracket 47 projecting upwards from the top edge of transverse wall 12.
- stop device 43 For each rod 44, stop device 43 comprises a rocker arm 48, in turn comprising a central portion defined by a sleeve 49 fitted in rotary and axially-sliding manner to relative rod 44; and two arms 50, 51 extending downwards.
- Arm 50 extends along through channel 42 and inwards of relative rocker arm 29; and arm 51 extends outwards of relative rocker arm 29, and is fitted on its free end with a follower mounted to slide along a track 52 formed on the surface of first arm 28 of relative rocker arm 29 facing relative longitudinal wall 9, 10.
- each track 52 comprises a first portion 53 closer to transverse wall 11 and located a first distance from axis 8; and a second portion 54 closer to transverse wall 12 and located a second distance, smaller than the first distance, from axis 8.
- the follower on each arm 51 is held contacting relative track 52 by a coil spring 55, which is fitted to relative rod 44, is compressed axially between relative sleeve 49 and relative bracket 47 to keep relative sleeve 49 in contact with the end of relative sleeve 45, and is * compressed torsionally to move relative arm 50 towards axis 8 and the other arm 50.
- each arm 50 has a sickle-shaped end portion 56, which extends, at rest, inside through channel 42, and has an appendix 57 projecting from sickle-shaped portion 56 towards transverse wall 11.
- arms 50 are positioned, inside through channel 42, facing and substantially contacting plate 18, and appendixes 57 are positioned, by springs 55, contacting the lateral wall of plate 18 to keep sickle-shaped portions 56 in such a position as to surround a capsule 2 fed downwards into through channel 42, and hold capsule 2 in the infusion position.
- Capsule 2 is fed downwards into through channel 42 by a tubular body 58, which is fitted to frame 7, over through channel 42, and defines a vertical feed channel 59 for feeding capsule 2 into through channel 42.
