Abstract:
A metering pump assembly includes a metering space (6) and a displacement body (8) which is linearly movable via a conrod (10). A helical spring (20) designed as a compression spring (20) impinges the conrod (10) with a force in a movement direction. The helical spring (20) at at least one axial end (24) is designed such that in a relaxed condition an end (26) of a spring wire projects axially with respect to a connecting winding (28).
