Title (EN) DISCHARGE PUMP
(FR) POMPE À DÉCHARGE
(JA) 吐出ポンプ
Abstract:
(EN) This discharge pump (2) is provided with: a stationary suction part (A) which is equipped with a cylinder (A1) having a first check valve (V1) provided to a lower part thereof and a mounting member (A3) to be mounted to the neck part of a container; and an actuating member (B) which is equipped with a discharge head (B4), a stem (B2), a piston guide (B1) and an annular piston (B3), and which has a second check valve (V2) formed between the lower end of the annular piston and the lower part of the piston guide, wherein provided to a part where the stem and the piston guide are fitted to each other is an engagement means (E) to restrict the stem and the piston guide from rotating in an un-engaged manner with respect to each other when the actuating member is unscrewed and lifted from the stationary suction part.
(FR) L'invention concerne une pompe à décharge (2) comprenant : une partie d'aspiration fixe (A) qui est équipée d'un cylindre (A1) ayant un premier clapet de non-retour (V1) disposé sur une partie inférieure de celui-ci et un élément de montage (A3) à monter sur la partie col d'un récipient ; et un élément d'actionnement (B) qui est équipé d'une tête de décharge (B4), d'une tige (B2), d'un guide de piston (B1) et d'un piston annulaire (B3), et qui a un second clapet de non-retour (V2) formé entre l'extrémité inférieure du piston annulaire et la partie inférieure du guide de piston, un moyen de mise en prise (E) étant prévu sur une partie où la tige et le guide de piston sont ajustés l'un sur l'autre, afin d'empêcher la tige et le guide de piston de tourner d'une manière non engagée l'une par rapport à l'autre lorsque l'élément d'actionnement est dévissé et soulevé de la partie d'aspiration fixe.
(JA) 吐出ポンプ(2)は、下部に第1逆止弁(V1)を備えたシリンダ(A1)と、容器体の口頸部へ装着される装着部材(A3)と、を備える固定吸引部(A)と、吐出ヘッド(B4)と、ステム(B2)と、ピストンガイド(B1)と、環状ピストン(B3)と、を備え、環状ピストンの下端部とピストンガイドの下部との間に第2逆止弁(V2)が形成される作動部材(B)と、を備え、ステムとピストンガイドとの嵌合部分には、作動部材の固定吸引部への螺合を解除して、作動部材を固定吸引部から上昇させる際に、ステムとピストンガイドとが相互に空回りすることを規制する係合手段(E)が設けられている。
