#This is a 371 filing of International Patent Application No. PCT/SE2003/001295 filed Aug. 20, 2003 and published on Mar. 4, 2004 under publication number WO 2004/018345 A and claims priority benefits from Swedish Patent Application No. 0202487-5 filed Aug. 21, 2002.

#The present invention relates to a device for compensating for pressure drop in a product pipe through which a liquid flows, and a system for filling containers comprising such a device. The invention concerns more specifically such a device comprising a collapsible tube portion which is connectible to a product pipe.

#A device for compensating for pressure drop in a product pipe through which a liquid flows is used, for instance, in the food industry for filling containers in a filling machine.

#The invention will now be described in more detail by way of non-limiting embodiments and with reference to the accompanying drawings. Equivalent components in both embodiments have been given the same reference numerals.

#FIG. 1 is a side view of a device according to the invention in an unaffected state.

#FIG. 2 is a side view of a device according to the invention in a state affected by pressure drop.

#According to the present invention, a device for compensating for pressure drop in a product pipe is provided. Such a device is extremely advantageous in a system for filling of containers with liquid food contents, the contents being supplied through said product pipe.

#Subsequently some preferred embodiments of the present invention will be described, components having an equivalent and similar function being throughout given the same reference numerals.

#FIG. 1 to which reference is made, illustrates a first embodiment of an inventive device 1.
