摘要： A double-acting or lift and force pump for ejecting a product from a container, with a housing in which a piston with an axial bore is axially slidable and sealed by a first housing portion, with a hollow piston rod which extends the axial bore of the piston and is slidable in an opening of a piston rod has at its free end a tightly fastened actuating head, wherein, when the actuating head is actuated, the piston builds up a pressure against the force of a restoring spring in a pressure chamber of the housing, wherein an outlet duct connected to the bore extends through the actuating head and through a check valve up to an ejection opening for the product, and with at least one opening in a second housing portion between the first housing portion and the closing cap. The piston in the non-actuated state thereof under the restoring spring force leaves a passage between the pressure chamber and the at least one opening in the second housing portion, wherein a section of the outlet duct adjacent the check valve has between two cup-shaped sleeves of the actuating head, which are laterally tightly placed against each other, a groove formed on the outer side of the inner sleeve, wherein the groove is covered by the outer sleeve and extends up to an expansion chamber formed in front of the outlet opening formed in the bottom of the outer sleeve, and wherein a germ-killing and bacteria-killing medium is arranged in the expansion chamber, wherein the medium permits flow of the liquid to the outlet opening, wherein the dispensing stroke volume of the piston corresponds to the volume of the drop of the liquid, and wherein the width of the outlet opening prevents a spraying effect.

摘要： A double-acting pump for ejecting a product from a container, with a housing in which a piston with an axial bore is axially slideable and sealed by a first housing portion, with a hollow piston rod which extends the axial bore of the piston and is slideable in an opening of a closing cap of the housing and container. When an actuating head is actuated, it presses the piston against the force of a restoring spring toward a connecting pipe portion for an immersion pipe provided in the housing, so that a pressure is built up in a pressure chamber of the housing which presses a first valve closing piece in the connecting pipe piece against a first valve seat. In the non-actuated state, the piston releases as a result of the restoring force of a spring a passage between a pressure chamber and at least one opening in a second housing portion, wherein the connecting pipe piece has a second valve seat and a second valve closing piece which, in a position of the double-acting pump in which an actuating head is lower than the connecting pipe piece, the second valve closing piece assumes its closing position at the second valve seat, and the second valve closing piece assumes its open position in an inverted position in which the actuating head is higher than the connecting pipe piece.
