Abstract

Fluid conveyance apparatuses for freezing liquids having a pump must be able to be emptied. A direction reversal valve can be provided therefor on the pump for the purpose of reversing the conveyance direction. In the fluid conveyance apparatus (2) proposed here, the possibility for a direction reversal of the conveyance direction (41A, 41B, 42A, 42B) is achieved by a simple construction measure using the valve apparatus (30), which can be produced easily. The fluid conveyance apparatus is provided in particular for vehicles which are naturally subjected to significantly varying temperatures.
