Title
(EN) HAND OPERATED PUMP
(FR) POMPE À MAIN
Abstract
(EN)
A hand operated pump of an internal combustion engine fuel system comprising an outer casing (1) and in its cavity (4) a slidably disposed piston (2), wherein between the outer casing (1) and the piston (6) is mounted at least one locking ring (6), which is fixed in the outer casing (1), while the outer casing (1), the piston (2) and the locking ring (6) are made of the same type of plastic, when disposed between the outer casing (1) and the piston (2) is mounted at least one sealing cuff (5) which is fixed in the piston (2) and which is made of fluorine silicone.
(FR)
Cette invention concerne une pompe à main d'un circuit d'alimentation de moteur à combustion interne, comprenant un boîtier externe (1) et, dans sa cavité (4), un piston disposé de manière coulissante (2). Entre le boîtier externe (1) et le piston (6) est monté au moins un anneau de verrouillage (6) qui est fixé dans le boîtier externe (1). Le boîtier externe (1), le piston (2) et l'anneau de verrouillage (6) sont constitués du même type de plastique. Entre le boîtier externe (1) et le piston (2) est monté au moins un manchon d'étanchéité (5) qui est fixé dans le piston (2) et qui est constitué de silicone fluorée.
