A filling machine for filling a container with a pourable food product, comprising: - a tank which may be filled with said pourable food product; - a support structure; - a first fluidic line through which said pourable food product may flow, connected with said tank and fluidically connectable in a selective manner with the inner volume of said container; - at least one filling valve movable between a closed configuration in which it prevents said pourable food product from flowing along said first fluidic line and an open configuration in which allows said pourable food product to flow along said first fluidic line; and - at least one distributor comprising at least one duct (21, 22, 23, 24) defining, with a cavity of filling valve, at least partially a second fluidic line along which a fluid different from said pourable food product may flow towards the inner volume of said container; said distributor further comprising at least a first and a second control valve (25, 26, 27, 28) each displaceable between a first configuration in which said fluid is prevented from flowing along said second fluidic line towards the inner volume of said container and a second configuration in which said fluid is allowed to flow along said second fluidic line; at least one of said control valves (25, 26, 27, 28) may either be left in said respective first configuration over the whole operation of said filling machine or be displaced between respective said first and second configuration during at least one step of the operation of said filling machine on the basis of at least one parameter between the type of container and the type of pourable food product; said distributor comprising a first body housing said control valves (25, 26, 27, 28); said filling valve comprising a third body connected to said first body and said cavity is comprised in said third body; said first fluidic line comprising a duct connected to said tank and engaging a hole defined by said first body, and said cavity; characterized in that said distributor is connected in a releasable manner with said filling valve; said distributor is suitable for several types of said containers and pourable food products; said filling valve is specific for a particular type of said container and pourable food products; said distributor comprises a pressure sensor sensible to the pressure inside said cavity; said pressure sensor is fluidically connectable to the inside of said cavity in a selective manner. - a tank which may be filled with said pourable food product; - a support structure; - a first fluidic line through which said pourable food product may flow, connected with said tank and fluidically connectable in a selective manner with the inner volume of said container; - at least one filling valve movable between a closed configuration in which it prevents said pourable food product from flowing along said first fluidic line and an open configuration in which allows said pourable food product to flow along said first fluidic line; and - at least one distributor comprising at least one duct (21, 22, 23, 24) defining, with a cavity of filling valve, at least partially a second fluidic line along which a fluid different from said pourable food product may flow towards the inner volume of said container; said distributor further comprising at least a first and a second control valve (25, 26, 27, 28) each displaceable between a first configuration in which said fluid is prevented from flowing along said second fluidic line towards the inner volume of said container and a second configuration in which said fluid is allowed to flow along said second fluidic line;
