Abstract (en)
[origin: EP0437131A1] The pump (1) comprises: a body (4) fitted with an end piece (9) for connecting to a plunger tube (13), equipped with an inlet valve (15); a cylinder (16) suitable for sliding in the body through the action of a push button (17) pushed in by the user, in opposition to elastic return means (18); a lower piston (34) linked to the cylinder. The lower piston (34) comprises a central passage (35) in which, approximately at mid-height, arms (36) extend radially and form a kind of star, these arms (36) carrying a central rod (37) which is coaxial with the piston (34) and of smaller diameter, elastic means for returning the cylinder (16) and the lower piston (34) being constituted by a helical spring (18), one end of which is engaged in the central passage of the piston (34) and bears against the radial arms (36) and the other end of which bears against a stop (s) integral with the internal wall of the body (4). <IMAGE>
