FIELD: pump engineering. SUBSTANCE: distant end of a hose is provided with one-way valve. The diametric plane of the valve housing is provided with two axles parallel to each other and to the base. Pair tabs are movably coupled with the bottom axle. The tabs are plates with openings for axles at one end and loop corresponding to the loop at the place of a contact with the housing that bears on the top axle when it is in the middle position. The axle serves as a stop to avoid one- way turning over of the opposite tabs. As the tabs are not sealed, the remainder liquid ingresses into the initial tank. EFFECT: improved design. |
