The pump (1) consists of a cylindrical housing (3) containing a pumping chamber (2) with an inner piston (7) linked to an actuator (6) and equipped with a return spring (9). It also has a precompression chamber (5) with a second piston (10) and return spring (11), a feed channel (4) and a dispensing nozzle (17) with a jet (20). The precompression chamber is situated in an extension of the pumping chamber so that the liquid inside the pumping chamber passes directly into the precompression chamber when the actuator is operated. The nozzle jet is fixed relative to the body of the pump and has an outlet aperture (21) situated on an axis (Z) which is orthogonal to the axis (X) of the pump housing. |
