Title (EN) INJECTION VALVE DEVICE AND AEROSOL TYPE INJECTOR WITH THE DEVICE
(FR) DISPOSITIF A SOUPAPE D"INJECTION ET INJECTEUR DE TYPE AEROSOL UTILISANT CE DISPOSITIF
Abstract: front page image
(EN)An injection valve device of an aerosol type injector, wherein a tube part (23) is provided at the lower part of a stem (22) and a slidably contacting projected part (23a) is formed on the inner peripheral surface of the tube part, an adjusting member (14) is stored in the large diameter part (12) of a housing (10), the center axis part (17) of the adjusting member is inserted into the tube part (23), and the tube part is stored in the housing, a vertical groove (17a) is provided in the center axis part, the slidably contacting projected part (23a) is pressed against the portion of the center axis part having the vertical groove, and a recessed part (17b) is provided in the lower part of the vertical groove so that, when a stem (22) is pressed strongly, the slidingly contacting projected part (23a) can come into the recessed part (17b) with an allowance, whereby the amount of injection can be increased and decreased by the degree of depression of the stem without deteriorating the controllability by the wobble of the stem, making unstable the amount of injection, or noticeably deteriorating an assemblage.
(FR)L"invention concerne un dispositif à soupape d"injection du type injecteur à aérosol. Ce dispositif comprend un tube (23) situé sur la partie inférieure d"une tige (22), un élément saillant (23a) à contact coulissant formé sur la surface périphérique interne du tube et un élément d"ajustage (14) situé dans la zone de grand diamètre (12) d"un logement (10). L"élément d"axe central (17) de l"élément d"ajustage est introduit dans le tube (23) et le tube est placé dans le logement. L"élément d"axe central comprend une rainure verticale (17a). L"élément saillant (23a) à contact coulissant est appuyé contre la partie de l"élément d"axe central comprenant la rainure verticale. La partie inférieure de la rainure verticale comprend un évidement (17b) permettant, lorsqu"une tige (22) est appuyée fortement, de faire venir l"élément saillant (23a) à contact coulissant dans l"évidement (17b). Ainsi, on peut augmenter ou réduire la dose injectée en fonction du degré de dépression de la tige sans les problèmes de contrôlabilité induits par la souplesse de la tige, rendant instable la dose d"injection ou endommageant sensiblement l"ensemble.
