    • A gas supply (30) supplies pressurised gas to a nozzle (1) such that a flow of gas is discharged through an aperture (77) defined between a lip (3) of the nozzle and a vibrating diaphragm (9). A liquid dispenser (42) introduces a metered quantity of liquid into the gas flow such that the liquid droplets are atomised by the vibrating diaphragm. The diaphragm is held under tension so that it is vibrated by the gas flow. The supply of gas may be a manually operated displacement or diaphragm pump or may be a pressurised gas container. Metered doses may be dispensed for oral inhalation without providing external energy source for the vibration of the diaphragm.
    • 气体供给装置(30)向喷嘴(1)供应加压气体,使得气体流通过限定在喷嘴的唇缘(3)和振动膜(9)之间的孔(77)排出。 液体分配器(42)将计量的液体引入到气流中,使得液滴被振动膜片雾化。 隔膜保持在张力下,使其由气流振动。 气体的供应可以是手动操作的位移或隔膜泵,或者可以是加压气体容器。 计量剂量可以分配用于口腔吸入,而不为隔膜的振动提供外部能源。

    • A two-stage pump (9) for a continuous ink jet printing system comprises a first stage (A) which includes a chamber (91, 92) having an inlet (93) and an outlet (94) via a non-return valve (115) to a channel (95). The first stage chamber (91, 92) is divided by a dished diaphragm (101) movable by a first cylinder (97) mounted on a pump shaft (98). The pump (9) has a second stage (B) comprising a chamber (104, 105) having an inlet (106) from the channel ((95) and an outlet (107). The second stage chamber (104, 105) is divided by a rolling diaphragm (116) movable by a second cylinder (108) mounted on a pump shaft (98). The cylinders (97, 108) are arranged to be driven, and thus drive their respective diaphragms (101, 116), 180 DEG out of phase so that ink and air enter the first stage chamber (91, 92), are pressurised by the first cylinder (97) and passed through the channel (95) to the second stage chamber, and are further pressurised and passed out of the outlet (107) of the second stage chamber (104, 105).
    • 用于连续喷墨打印系统的两级泵(9)包括第一级(A),其包括具有入口(93)和通过止回阀(93)的出口(94)的腔室(91,92) 115)到通道(95)。 第一级腔室91,92被安装在泵轴(98)上的第一气缸(97)可移动的碟形隔膜(101)分开。 泵(9)具有第二级(B),其包括具有从通道(95)和出口(107)的入口(106)的室(104,105),第二级室(104,105) 由通过安装在泵轴(98)上的第二气缸(108)可移动的滚动隔膜(116)分开,气缸(97,108)被布置成被驱动,从而驱动它们各自的隔膜(101,116), 180度异相,使得油墨和空气进入第一级室(91,92),由第一缸(97)加压并通过通道(95)进入第二级室,并进一步加压并通过 离开第二级室(104,105)的出口(107)。
