Abstract

<P>Cette pompe, comme les pompes connues, comporte deux membranes disposées chacune dans une enceinte respective, qu'elles divisent en une chambre d'entraînement 6, 7 et une chambre de pompage 8, 9 et reliées l'une à l'autre par un accouplement rigide 20 qui synchronise leurs mouvements et, un distributeur 10, dont l'obturateur est un tiroir-piston 23, est muni de billes d'arrêt 25, 26, est relié mécaniquement à l'accouplement rigide et, de ce fait, dirige le gaz comprimé servant de fluide moteur alternativement vers l'une et l'autre chambre d'entraînement dans les positions extrêmes de la course des membranes 4, 5. </P><P>Dans la pompe selon l'invention, la liaison mécanique entre l'origine rigide d'accouplement et le tiroir-piston est assurée par une barre formant ressort 11. </P><P>On obtient ainsi une pompe compacte, d'une grande sûreté de fonctionnement, pouvant etre utilisée, par exemple, dans des vêtements de protection.</P><P> This pump, like the known pumps, comprises two membranes each arranged in a respective chamber, which they divide into a driving chamber 6, 7 and a pumping chamber 8, 9 and connected to one another. other by a rigid coupling 20 which synchronizes their movements and, a distributor 10, whose shutter is a piston-slide 23, is provided with stop balls 25, 26, is mechanically connected to the rigid coupling and, of this fact, directs the compressed gas acting as the driving fluid alternately to one and the other drive chamber in the extreme positions of the stroke of the membranes 4, 5. </ P> <P> In the pump according to the invention the mechanical connection between the rigid coupling origin and the piston slider is ensured by a spring bar 11. </ P> <P> Thus, a compact pump with a high degree of operational safety can be obtained. used, for example, in protective clothing. </ P>

Description

распределительным устройством - золотником 13. Шарнирное крепление стержн  21 выполнено в виде отверсти  22 в корпусе 1. Сечение стержн  21 может быть круглым или пр моугольным . Насосные камерою 5 и 6 снабжены всасывающими 23 и 24 (фиг.2 и нагнетательными 25 и 26 клапагами соббщающими камеры соответственно со всасывающим 27 и нагнетательным 28 патрубками.the distributor is a spool 13. The hinged fastening of the rod 21 is made in the form of an aperture 22 in the housing 1. The cross section of the rod 21 can be round or rectangular. Pumping chambers 5 and 6 are equipped with suction 23 and 24 (figure 2 and pressure valves 25 and 26 with valves for the chambers with suction 27 and pressure pipes 28, respectively.

При подаче приводного газа под давлением в патрубок 17 или 18 он по осевому каналу 16 золотника 13 и каналу 10 или 11 поступает в приводную камеру 7 или 8 (например, в камеру 8 в исходном положении, изображенном на фигурах). Под действием давлени  газа мембраны 3 и 4 со штоком 2 начинают перемещатьс  и объем насосных камер 5 и 6 мен етс  . Перекачиваема  среда поступает в расшир ющуюс  камеру 5 через всасывающий клапан 23 и вытесн етс  из камеры 6 к потребителю через нагнетательный клапан 26.When supplying the drive gas under pressure to the nozzle 17 or 18, it passes through the axial channel 16 of the spool 13 and channel 10 or 11 into the drive chamber 7 or 8 (for example, into the chamber 8 in the initial position shown in the figures). Under the action of gas pressure, the membranes 3 and 4 with the stem 2 begin to move and the volume of the pump chambers 5 and 6 change. The pumped medium enters the expansion chamber 5 through the suction valve 23 and is expelled from the chamber 6 to the consumer through the discharge valve 26.

В процессе хода штока 2 вправо пружинный стержень 21 изгибаетс  и .стремитс ч переключить золотник 13 в левое по фиг. 1 положение. Однако последний удерживаетс  фиксатором 15 В определенный момент в конце хода штока усилие пружинного стержн  21 превышает усилие фиксации золотника 13 и он переключаетс  в противоположное левое по фиг. 1 положение. В этрМ положении приводной газ под давлением поступает по каналу 10 , в приводную камеру 7, а из приводной камеры 8 сбрасываетс  по каналам-12 и 20 в атмосферу. Мембраны 3 и 4 со штоком 2 движутс  в противоположную сторону (влево по фиг. 1) иDuring the stroke of the rod 2 to the right, the spring rod 21 is bent and it is time to shift the valve 13 to the left in FIG. 1 position. However, the latter is held by retainer 15 At a certain moment at the end of the stroke of the rod, the force of the spring rod 21 exceeds the force of fixing the spool 13 and it switches to the opposite left in FIG. 1 position. In the ePM position, the drive gas under pressure enters through channel 10, into the driving chamber 7, and from the driving chamber 8 is discharged through channels 12 and 20 into the atmosphere. Membranes 3 and 4 with stem 2 move in the opposite direction (to the left in FIG. 1) and

рабочие процессы в насосных камерах 5 и 6 мен ютс  местами. В конце хода штока возрастает сила, действующа  со стороны изогнутого стержн  21 на золотник 13, и он, преодолева  усилие фиксации фиксатора 14,переключаетс  в исходное, правое по чертежу положение.the work processes in pump chambers 5 and 6 are interchanged. At the end of the stroke of the rod, the force acting from the side of the bent rod 21 on the spool 13 increases, and overcoming the force of fixing the latch 14, it switches to the initial position right in the drawing.

Далее цикл работы насоса повтор ете  .Then repeat the cycle of the pump.

Простота конструкции управл ющего звена - пружинного стержн  21 обуслашливает упрощение конструкции всего насоса. The simplicity of the design of the control link - spring rod 21 explains the simplification of the design of the entire pump.
