The present invention relates to a dispensing device comprising an expandable buffer reservoir (16) having an inlet and an outlet, a dispensing mechanism (2) of constant volume having an inlet and an outlet, a liquid reservoir filled with pressurized liquid (16), which is connected to the inlet (6) of the expansion reservoir (16) and is configured so that liquid can only flow from the liquid storage portion (6) to the expandable buffer reservoir (16) An outlet of a buffer reservoir (16) expandable so that the liquid flows only from the expandable buffer reservoir (16) to the dispensing reservoir (2) is connected to the dispensing reservoir An outlet valve (8) connected to the inlet of the expansion valve (2), and a volume changer (4) arranged to change the volume of the expandable buffer reservoir (16), the expandable buffer reservoir Expanding the current volume of (16) to expanded volume is an expandable Causing the liquid to be drawn from the liquid storage part (6) into the expandable buffer reservoir (16) until the buffer reservoir (16) is filled with liquid, Compressing the expansion volume causes the discharge of liquid from the expandable buffer reservoir (16) to the dispensing reservoir (2) until the dispensing reservoir (2) is filled with liquid. In addition, the dispensing reservoir (2) is configured to release its liquid contents during a single puff of the user.BACKGROUND OF THE INVENTION本発明は、吸込み口および出口を有する拡張可能な緩衝貯蔵部(16)と、吸込み口および出口を有する一定容積の分注機構(2)と、加圧された液体で充填された液体貯蔵部分(6)に接続されて液体が液体貯蔵部分(6)から拡張可能な緩衝貯蔵部(16)へのみ流れることができるように構成された、拡張可能な緩衝貯蔵部(16)の吸込み口に接続された吸込み弁(18)と、液体が拡張可能な緩衝貯蔵部(16)から分注貯蔵部(2)までのみ流れるように拡張可能な緩衝貯蔵部(16)の出口を分注貯蔵部(2)の吸込み口に接続する出口弁(8)と、拡張可能な緩衝貯蔵部(16)の容積を変更するよう構成された容積変更器(4)とを備え、拡張可能な緩衝貯蔵部(16)の現在の容積を拡張容積に拡張することは、拡張可能な緩衝貯蔵部(16)が液体で充填されるまで、液体貯蔵部分(6)から拡張可能な緩衝貯蔵部(16)への液体の引込みを生じさせ、拡張可能な緩衝貯蔵部(16)の拡張容積を圧縮することは、分注貯蔵部(2)が液体で充填されるまで、拡張可能な緩衝貯蔵部(16)から分注貯蔵部(2)への液体の排出を生じさせる。さらに、分注貯蔵部(2)は、ユーザの一度の吸煙中にその液体内容物を放出するよう構成される。【選択図】図1
