Abstract:
The present invention relates to a metering pump for a metering device, the metering pump being connectable to a storage container. The metering pump thereby comprises a non-return valve which has sealing elements on the base-side, which sealing elements enable internal sealing of the metering pump. In addition, the present invention relates to a metering device in which the metering pump according to the invention is connected to a storage container.

Claim (Index 1):
A metering pump for a metering device for metered dispensing of a liquid which is connectable to a storage container, the metering pump comprising:\n a cylindrical pump body which comprises a first hollow cylindrical pump body portion which is open in the direction of the storage container and a second hollow cylindrical pump body portion which is open in the direction of an actuation body; an inner hollow cylinder which is open at both ends which is mounted on the first pump body portion and is arranged concentrically to the latter; a plunger which has a thoroughgoing channel which is mounted concentrically in the pump body and moveably in the inner hollow cylinder, and is configured to form a seal with an inner wall of the inner hollow cylinder; an actuation body which is connected to the pump body and mounted moveably relative to the pump body, which actuation body has, on an upper end, an outlet for liquid and a recess which is open in the direction of the second pump body portion, wherein a liner is received inside the recess, which liner has a recess which is open in the direction of the second pump body portion, the liner being disposed to form a fluidic seal relative to the plunger and having a liquid channel through which a liquid can be guided from the recess of the liner to the outlet of the actuation body; and a non-return valve which is mounted moveably and configured to form a fluidic seal relative to the recess of the liner being disposed inside the recess of the liner, which non-return valve, in the unactuated state of the metering pump, fluidically seals the channel of the plunger relative to the recess of the liner and opens the channel of the plunger and also the liquid channel of the liner during actuation of the metering pump, the non-return valve having at least one sealing element which enables fluidic sealing of the non-return valve relative to the plunger.
