A water hammer arrester comprises a cylindrical body housing a piston for free sliding reciprocal movement and a connector for connection to a water conduit system which carries water under pressure. An abutment-bumper combination is interposed between piston and connector to avoid the ping which would be produced is these two elements of the assembly were to collide during reciprocation of the piston.
Cette invention concerne un anti-coup de bélier formé d'un corps cylindrique à l'intérieur duquel est logé un piston à mouvement alternatif et un raccord pour son raccordement à une tuyauterie d'eau sous pression. Une butée/pare-choc est interposé entre le piston et le raccord pour prévenir le bruit qui se produirait si ces deux éléments s'entrechoquaient pendant le va-et-vient du piston.
