    • A hand operable pump device for pumping fluids includes a hollow body and an oval piston. The hollow body includes an inlet port and an outlet port. The inlet port is provided with a one-way valve permitting fluid flow into the pump. The outlet port is provided with a one-way valve permitting fluid flow out of the pump. The oval piston is designed to be pressed inwardly from an initial position by the hand, decreasing the volume of an oval chamber with a corresponding oval cross-section. The chamber is located within the pump and is fluidically connected with the inlet and outlet ports. The oval piston is further designed to return to the initial position when released, increasing the volume of the chamber.
    • 用于泵送流体的手动泵装置包括中空体和椭圆形活塞。 中空体包括入口和出口。 入口端口设置有允许流体流入泵的单向阀。 出口端口设有允许流体从泵中流出的单向阀。 椭圆形活塞被设计成从手的初始位置向内压,减小具有相应的椭圆形横截面的椭圆形腔的体积。 腔室位于泵内,并与入口和出口流体连接。 椭圆形活塞进一步设计成在释放时返回到初始位置,增加了腔室的体积。
