At this time, since the float 28 descends to the position corresponding to the pumping water lower limit level detecting means 27, the photoelectric element sensor 1 as the detecting means 27 detects the float 28 and generates a lower level detection signal.

Abstract

Dispositif de pompage à vide capable d'accumuler de l'eau de façon stable et sûre dans un réservoir à eau et extrêmement efficace pour économiser de l'énergie électrique. Ce dispositif comprend essentiellement un tube de Geissler (31) servant de moyen d'indication du vide et situé sur la surface supérieure d'un réservoir de pompage à vide (2), dans lequel se trouve un conduit d'admission (22), ainsi qu'une pompe à vide (1) reliée au réservoir par l'intermédiaire d'un conduit d'aspiration (21). Sur une surface latérale du réservoir de pompage à vide (2) est situé un conduit (25) indiquant la surface de l'eau pompée, dans lequel est situé un flotteur (28), dont les extrémités supérieure et inférieure sont ouvertes vers un réservoir de pompage à vide (2) et dont une circonférence extérieure comporte des moyens de détection respectifs (26, 27) servant à détecter la position du flotteur. Les sorties des moyens de détection respectifs (26, 27) sont transférées vers un moyen de commande (29) de la pompe à vide (1). De plus, un conduit d'évacuation (23) dans lequel est situé un clapet de retenue (24), relie une partie inférieure du réservoir de pompage à vide (2) au réservoir d'eau (4), de manière à mettre en service une vanne de retenue et d'écoulement (43) du réservoir d'eau (4), ce qui permet à l'eau contenue dans ce réservoir de circuler à travers un conduit d'évacuation (42) en direction des usagers.
