Title (EN) PULSATOR
(FR) GENERATEUR DE PULSATIONS
Abstract:
(EN) A pulsator has two valve devices (1, 2) each of which is adapted to alternately subject a pulsation space to two different pressures. In order to avoid the two valve devices (1, 2) from disturbing each other during the alternations between the two pressures a third valve device (23) is arranged, for closing communication between one of the valve devices and the lower one of said two pressures, when the other valve device is operated to alternate the pressure in the pulsation space from the lower one to the higher one of said two pressures.
(FR) Générateur de pulsations comprenant deux dispositifs à soupape (1, 2) qui sont prévus pour produire de façon alternée, deux pressions différentes dans un espace de pulsation. Afin d'éviter que les deux dispositifs à soupape (12) se perturbent entre eux au cours des alternances des deux pressions, un troisième dispositif à soupape (23) est prévu pour empêcher qu'un des dispositifs à soupape ne soit en communication avec la plus basse des deux pressions, lorsque l'autre dispositif à soupape fonctionne pour faire alterner la pression dans l'espace de pulsation, en partant de la pression la plus basse pour passer à la pression la plus élevée.
