Abstract: A manually-actuated fluid dispenser pump including a pump body (10) containing a pump chamber (20), said pump chamber (20) being defined between an inlet valve (30) and an outlet valve (40), a piston (50) being mounted to slide in said pump body (10) between a rest position and a dispensing position for dispensing the fluid contained in the pump chamber, said piston (50) being connected to, and in particular integral with, an actuating rod (60) provided with an expulsion channel (65), said inlet valve (30) including an inlet valve element (31) mounted to move in the pump body (10) and co-operating with said pump body (10) or with an element secured to or integral with said pump body to define the open and the closed positions for said inlet valve (30), said outlet valve (40) including an outlet valve element (41) mounted to move in the pump body (10) and co-operating with said actuating rod (60) or with an element secured to or integral with said actuating rod to define the open and the closed positions for said outlet valve (40), said fluid dispenser pump being characterized in that, during actuation, said outlet valve (40) is urged into its closed position by the pressure from the fluid contained in the pump body (20), said outlet valve element (41) being moved into the open position of the outlet valve (40) by said inlet valve element (31) when the piston (50) reaches its dispensing position.

Abstract translation: 一种手动驱动的流体分配器泵，包括一个容纳泵室（20）的泵体（10），所述泵室（20）被限定在入口阀（30）和出口阀（40）之间，活塞（50） 被安装成在所述泵体（10）中在静止位置和用于分配容纳在所述泵室中的流体的分配位置之间滑动，所述活塞（50）与致动杆（60）连接并且特别地与致动杆（60）连接， 设置有排出通道（65），所述入口阀（30）包括入口阀元件（31），所述入口阀元件（31）安装成在所述泵体（10）中移动并与所述泵体（10）配合或者与固定到 或与所述泵体整体形成以限定所述入口阀（30）的打开和关闭位置，所述出口阀（40）包括安装成在所述泵体（10）中移动并与之协作的出口阀元件（41） 与所述致动杆（60）或固定到所述致动杆或与所述致动杆一体的元件以限定所述致动杆（60） e）所述出口阀（40）的关闭位置，所述流体分配泵的特征在于，在致动期间，所述出口阀（40）被来自容纳在泵体（20）中的流体的压力推动到其关闭位置， 当所述活塞（50）到达其分配位置时，所述出口阀元件（41）通过所述入口阀元件（31）移动到所述出口阀（40）的打开位置。
