摘要 |
The present invention provides a piston pump for liquid in which a sump is defined in a chamber into which sump liquid in the chamber flows due to gravity. A passageway leads from an outlet of the sump out of the chamber to a dispensing outlet. The dispensing outlet is at a height below the height of the sump outlet and fluid to exit the sump flows from the sump outlet upwardly in a first portion of the passageway to a height above the sump outlet then downwardly to the dispensing outlet. The chamber and its sump is defined between a piston chamber-forming member defining the chamber to be downwardly opening and a piston forming element axially slidable in the chamber. |
