A fluid dispensing device (5, 105, 205, 305, 405, 505) is disclosed having a housing (9, 109, 209, 309, 409, 509) and a fluid discharge device (8, 108, 208, 308, 408, 508). The fluid discharge device (8, 108, 208, 308, 408, 508) is arranged to be actuated by one or more levers (20, 21; 120, 121; 170; 220, 221; 320, 321; 420, 421; 520) so as to apply a force transversely to the fluid discharge device (8, 108, 208, 308, 408, 508) which is used to move a container (30, 130, 230, 330, 430, 530) forming part of the fluid discharge device (8, 108, 208, 308, 408, 508) along a longitudinal axis of the fluid discharge device (8, 108, 208, 308, 408, 508) to cause actuation of a pump forming part of the fluid discharge device (8, 108, 208, 308, 408, 508).A pre- load means (28; 27, 28; 39,40; 41, 42, 44; 144, 47a, 47b; 150, 152, 153; 224, 227; 342; 424x, 446; 425a; 427, 428; 560, 561) is used to prevent actuation of the pump until a pre-determined force is applied to each lever (20, 21; 120, 121; 170; 220, 221; 320, 321; 420, 421; 520) of sufficient magnitude to guarantee the production of a well developed efficient spray from the fluid dispensing device (5, 105, 205, 305, 405, 505).

L'invention concerne un dispositif (5, 105, 205, 305, 405, 505) de distribution de fluide comprenant un logement (9, 109, 209, 309, 409, 509) et un dispositif (8, 108, 208, 308, 408, 508) d'évacuation de fluide. Ce dispositif (8, 108, 208, 308, 408, 508) d'évacuation de fluide est conçu pour être actionné par un ou plusieurs leviers (20, 21, 120, 121, 170, 220, 221, 320, 321, 420, 421, 520) de manière à appliquer une force de façon transversale sur le dispositif (8, 108, 208, 308, 408, 508) d'évacuation de fluide utilisé pour déplacer un récipient (30, 130, 230, 330, 430, 530) formant partie dudit dispositif (8, 108, 208, 308, 408, 508) d'évacuation de fluide le long d'un axe longitudinal de celui-ci afin d'entraîner l'actionnement d'une pompe formant partie dudit dispositif (8, 108, 208, 308, 408, 508) d'évacuation de fluide. Un moyen de précharge (28, 27, 39, 40, 41, 42, 44, 144, 47a, 47b, 150, 152, 153, 224, 227, 342, 424a, 446, 425a, 427, 428, 560, 561) sert à empêcher l'actionnement de la pompe jusqu'à ce qu'une force prédéterminée suffisamment élevée soit appliquée sur chaque levier (20, 21, 120, 121, 170, 220, 221, 320, 321, 420, 421, 520), pour assurer la production d'une vaporisation efficace et bien développée depuis ledit dispositif (5, 105, 205, 305, 405, 505) de distribution de fluide.
