1. A unit for filling containers with a dose of product, comprising:
a line for transporting containers along a movement path and provided with a plurality of supporting seats for the containers arranged in succession along the movement path;
a filling station for filling the containers with a dose of the product;
the filling station comprising:
a containing seat in a containing element and configured to receive a dose of the product;
a movement device configured to move the containing element about a rotational axis for moving the containing seat along a closed path;
an adjusting device configured to move the containing element radially relative to the rotational axis, for adjusting the position of the containing seat between a receiving position for receiving the dose of the product and a releasing position for releasing the dose of the product from the containing seat into one of the containers transported by the transport line;
a forming substation where the dose of the product is formed inside the containing seat, provided with a releasing device for feeding the dose of the product inside the containing seat, when the containing seat is at the receiving position;
a compacting substation where the dose of the product is compacted inside the containing seat, provided with a compacting element movable along a compacting axis, parallel to the rotational axis, between a raised position in which the compacting element is outside the containing seat and a lowered position in which the compacting element is inside the containing seat, the compacting element moving from the raised position to the lower position when the containing seat is at the receiving position; and
a releasing substation where the dose of the product is released by an ejection device from the containing seat into said one of the containers transported by the transport line, when the containing seat is positioned in the releasing position,
the adjusting device being driven to place the containing seat in the receiving position at the forming substation and in the releasing position at the releasing substation,
wherein the forming substation comprises a hopper containing the product and the releasing device extends along a longitudinal axis between a first end cooperating with the containing seat when the containing seat receives the dose of the product and a second end communicating with the hopper for creating a feeding flow of the product from the second end towards the first end, for feeding the product into the containing seat in the receiving position,
wherein the longitudinal axis of the releasing device is at an oblique angle of inclination to a horizontal plane, whereby the first and second ends are offset from a common axis which is parallel to the rotational axis; and
wherein the compacting substation is located along the closed path between the forming substation and the releasing substation, and the releasing device is removed from the containing seat when the compacting element moves from the raised position to the lowered position, whereby the compacting element does not interfere with the releasing device.
