Title (EN) MANUAL DEVICE FOR CLEARING BLOCKED WASTE PIPES
(FR) DISPOSITIF MANUEL POUR DEBOUCHER LES EGOUTS
Abstract:
(EN) The device has a flexible suction bell (2) fitted to a hand-pump (1), the bell being secured by a screw system (6) to a longitudinal end of the pump case (3). Inside the hand-pump (1) are arranged a piston rod (7) with a piston (8) and reversible seals (17, 19, 21) acting as valves. When the piston rod (7) is moved, depending on the valve setting, a vacuum or compressed air is produced. The device thus ensures perfect clearing of the blockages in waste pipes and offers excellent handling characteristics.
(FR) Le dispositif décrit possède une cloche d'aspiration souple (2) montée sur une pompe à main (1), la cloche étant fixée par un système à vis (6) à une extrémité longitudinale du boîtier (3) de la pompe. A l'intérieur de la pompe à main (1) sont disposés une tige (7) de piston ainsi qu'un piston (8), et des joints réversibles (17, 19, 21) servant de valves. Selon le réglage des valves, le déplacement de la tige de piston (7) produit soit une dépression soit de l'air comprimé, ce qui permet d'assurer un débouchage parfait des égouts tout en offrant une excellente maniabilité.
