Abstract: A valve including a shutter placed in a chamber which is arranged in the valve body and whose end is provided with a seat against which a plug-forming part of the shutter is pressed in the closed position of the valve and is remote in the open position thereof. The inventive valve also includes a magnetic control device provided with the shutter magnetic drive device disposed outside the chamber and displacing the shutter in the closed or open position thereof. The valve is characterized in that the magnetic control device includes at least one ball which is made of a magnetic material, disposed in the chamber and is coupled with an external magnetic drive device, wherein the ball is associated with the shutter in such a way that the shutter is driven in the chamber when the ball is moved by a magnetic drive device.

Abstract: The invention concerns a weight-filling machine wherein a force sensor consists of a deformable component having a base end (16) linked to a frame and an interface end (18) whereon is fixed a device for gripping (50) the container. The invention is characterised in that the gripping device (50) is coupled to the interface end by elastic means (72) urging the gripping device (50) towards a normal position wherein it is supported on a support surface (78) linked to the interface end (18), and the gripping device (50) is mobile relative to the interface end (18) along a protective direction, countering the elastic means (72), up to a stop position wherein it comes in contact with a stop surface (90) linked to the frame (86).
