An infusion machine includes a base receiving a collecting tray formed with
a bottom and a side wall and provided with a cover forming a support for
an infusion receptacle, as well as a device for producing infusion having
a head for an infusion outlet, overlying the support by a distance. The
support is movably mounted as to height relative to the tray by an
adjustment device to cause the distance to vary. The adjustment device
includes nesting members adjustable in height by sliding and distributed
over at least two opposite regions of the sidewall of the well and of the
periphery of the support.
