Problems solved by technology

However, most of the plug is moved by the product pressure generated during actuation, and actuations with different strengths and axial forces may cause changes in the injection characteristics
Especially in pumps - in which the obturator moves axially away from the dispensing orifice on pump action, too much movement of the obturator may result in a loss of spray quality and thus poor dosing

Embodiment Construction

[0030] [30] Referring to the drawings, a dispensing pump according to the present invention includes a pump body 10 in which at least one first piston 72 slides. The first piston 30 forms partly a pump chamber 20 and pump action causes a dose of product contained in the pump chamber 20 to be dispensed through a dispensing orifice 45 preferably formed in a dispensing head 40 . The pump comprises a stopper 38 which is arranged directly upstream of the dispensing orifice 45 and which is compatible with the dispensing orifice 45 since it can be moved and / or deformed between a position which blocks the dispensing orifice 45 and a position which opens said dispensing orifice. The dispensing holes 45 fit together. The pump chamber includes an inlet valve 70 which may be embodied in the form of a small ball 75 forming a valve member and cooperating with a valve seat 71 . The pump body 10 is preferably formed from a member that is integral with the obturator 38 within the pump body 10...

Abstract

The invention concerns a pump for distributing a fluid product comprising: a pump body (10); a pump chamber (20); at least one first piston (72) sliding inside said pump chamber (20) for distributing the fluid product; a distribution orifice (45); an obturator (38) that can be displaced and / or deformed between a closed position of the distribution orifice (45) and an open position of the distribution orifice (45), said chamber comprising an inlet valve (70) separating the pump chamber (20) from a dip tube (18) extending toward a fluid product reservoir (60), and; a bypass passage (74) provided between said dip tube (18) and the pump chamber (20), said bypass passage (74) being placed upstream from the inlet valve (70) and connecting the pump chamber (20) to the dip tube (18) when the pump is primed.

Description

technical field [0001] [01] The present invention relates to a fluid dispensing pump and a fluid dispensing device including such a pump. Background technique [0002] [02] Fluid product dispensing pumps are well known in the prior art, especially for dispensing products in the cosmetic, perfume or pharmaceutical fields. These pumps generally comprise a piston which slides in a pump body, in particular a pump chamber provided in the pump body, and which is capable of dispensing a dose of fluid product with each actuation of the pump . The pump chamber generally includes an inlet valve so that the dose expelled per actuation can be established. Also, especially with pharmaceutical products, some pumps sometimes include a stopper at the dispensing orifice in order to avoid contamination of the product between actuations. [0003] [03] One problem that arises with this type of pump is priming. In practice, before the first pump actuation, the pump chamber is filled with air...
