The invention claimed is: 1. A combination of a unit for the preparation of a beverage from a soluble product and a disposable cartridge containing said soluble product, said unit including a collecting device with a seat designed to receive said cartridge, said cartridge including at least one inlet port for a suspension fluid introduced into the cartridge and at least one outlet port for delivery of the beverage including said soluble product and said suspension fluid; and at least a throttling arrangement to give said beverage a laminar flow as it is released from the cartridge, wherein: said at least one throttling arrangement is formed between said unit and said cartridge, said at least one outlet port is defined by at least one breaking line on a bottom wall of said cartridge, said collecting device comprises at least one piercing member designed to pierce said cartridge at said breaking line, said at least one throttling arrangement includes at least one engaging portion of said piercing member that has a shape and dimensions substantially equal to those of said outlet port, and the piercing member has a height that allows an upper end of the piercing member to exert a pressure on the breaking line upon insertion of the cartridge in the seal of the collecting device. 2. A combination according to claim 1, wherein said engaging portion of said piercing member has a substantially cylindrical shape with circular section and wherein said breaking line in said cartridge has a substantially circular shape. 3. A combination according to claim 1, wherein said engaging portion of said piercing member has a diameter substantially equal to or slightly larger than that of said outlet port to form an interference fit between the outlet port of said cartridge and said piercing member. 4. A combination according to claim 1, wherein said collecting device comprises means for supporting said cartridge fitted in said seat. 5. A combination according to claim 4, wherein said supporting means comprise a supporting element provided with a surface designed to support at least part of the bottom wall of said cartridge. 6. A combination according to claim 5, wherein one or more passages are arranged between said supporting surface of said supporting element and the outer wall of said cartridge comprising said outlet port. 7. A combination according to claim 6, wherein said supporting element has a ring shape and wherein said passages are formed by a number of grooves arranged radially on the supporting surface of said supporting element. 8. A combination according to claim 6, wherein said passages are formed by a number of grooves arranged radially at least on the outer surface of the wall of said cartridge comprising said outlet port. 9. A combination according to claim 1, comprising at least one supporting element provided with a surface designed to support at least part of the wall of said cartridge which includes said outlet port, wherein said at least one throttling arrangement includes at least one rib protruding from the supporting surface of said supporting element and designed to abut against the wall of said cartridge comprising said outlet port and surround said outlet port. 10. A combination according to claim 1, comprising at least one supporting element provided with a surface designed to support at least part of the wall of said cartridge which includes said outlet port, wherein said at least one throttling arrangement includes at least one protruding rib which surrounds said outlet port in said cartridge, said rib being designed to abut against the supporting surface off said supporting element. 11. A combination according to claim 9, wherein said at least one protruding rib is continuous. 12. A combination according to claim 9, wherein said at least one protruding rib comprises one or more interruptions. 13. A combination according to claim 1, comprising at least one supporting element, provided with a surface designed to support at least part of the wall of said cartridge which includes said outlet port, wherein said at least one throttling arrangement includes the supporting surface of said supporting element and at least part of the wall of said cartridge comprising said outlet port. 14. A method for the preparation of a beverage from a soluble product contained in a disposable cartridge, the method comprising: fitting said cartridge in a preparation unit having a seat for said cartridge and a collecting device for said beverage, conveying a suspension fluid into said cartridge via an inlet port, delivering a beverage including said soluble product and said suspension fluid via an outlet port of said cartridge, throttling the beverage to give said beverage a laminar flow as it is released from the cartridge, creating said throttling by interaction between said unit and said cartridge, providing said outlet port with at least one breaking line on a wall of said cartridge, providing said collecting device with at least one piercing member designed to pierce said cartridge at said breaking line, and dimensioning the piercing member to have a height sufficient to exert pressure on the breaking line upon insertion of the cartridge in the seat of the collecting device. 15. A method according to claim 14, wherein said outlet port has a shape and dimensions substantially equal to those of said engaging portion. 16. A method according to claim 14, wherein said throttling is created between at least one rib protruding from the supporting surface of a supporting element of the cartridge present in said collecting device and the outer bottom wall of said cartridge, said at least one rib being designed to abut against the outer bottom wall comprising said outlet port of said cartridge and to surround said outlet port. 17. A method according to claim 14, wherein said throttling is created between at least one protruding rib which surrounds said outlet port in said cartridge and the supporting surface of a supporting element of said cartridge, said rib being designed to abut against the supporting surface of said supporting element present in said collecting device. 18. A method according to claim 14, wherein said throttling is created between the supporting surface of a supporting element of said cartridge present in said collecting device and at least part of the outer bottom wall of said cartridge comprising said outlet port.
