  • the forced opening of the venting element 45 leads to the advantage that a defined opening and closing can be achieved.
  • a pressure loss is avoided when sucking liquid 2 from the container 3, which could arise from the fact that in the container 3 nachströmende air must first open a valve. Accordingly, such a rapid return of the section 6 is supported in the unfounded starting position during suction.
  • the proposed pump 1 preferably has three valves, so the inlet valve 9, the outlet valve 10 and the vent valve 45, which are preferably all formed by the upper part and / or lower part.
  • the pump 1 is preferably made exclusively of plastic, in particular at least substantially (with the exception of the suction line 26) of injection molded parts.
  • the pump 1 is preferably constructed of less than ten, in particular of the highest five components, in particular in the illustration only from the actuator 32, the lower part 4 for mounting the actuator 32, the section 6 forming the upper part 5, the nozzle insert 21 and / or Suction line 26.
  • the rigid portion 14 is preferably made of the same material or a similar material as the lower part 4.
  • the soft plastic which forms the section 6 and in particular also the edge 7, the outlet valve body 15, the holding section 16, the valve flap 11, the biasing element 13, the holding section 47 and / or the sheath 49, most preferably by integral formation and / or one-piece injection, is preferably a thermoplastic silicone or other suitable material that can be firmly and / or tightly connected in particular by bi-injection with the rigid portion 14.
