Abstract (en)
[origin: EP0696480A1] The pump has a body (1) with a inlet (11) discharging into a measuring chamber (12). The measuring chamber has an inlet valve (20) and a piston (3) with a plunger (30) which has an axial jet (31). The jet enlarges in its lower part into a corolla (32) receiving a flexible membrane lining (4). The jet internal channel (31a) leads to an outlet valve (40). The outlet valve is part of a single deformable piece forming the membrane constituted from a lower U collar (42), assembled on the corolla of the plunger. At the top is fastened an external cylindrical sealing skirt (43) and the piston back, in its rest position, extends an annular flange (44) at the membrane junction on the body. At the upper narrow end of the conical outlet valve a cut-out (4) in the membrane is edged by a lip opening onto the outlet orifice.
