Claim:
1. A flow test machine comprising: a test piston, a test channel, a test weight, and a drive unit, wherein the drive unit is connected to a bracket that is configured for being switched into a closed position and a release position; and wherein a weight force of the test weight is applied to the test piston and the test piston is moved through the test channel with the aid of the weight force, wherein in a drive state, the drive unit is configured for raising or lowering the test weight, and wherein, on at least one stretch along the test channel between a first, starting position of the test piston and a second, end position of the test piston the weight force is applied to the test piston in combination with an additional actuating force by the drive unit during a movement of the test piston in a first direction of the weight force, said movement being accelerated in comparison to movement of the test piston under an effect of the weight force alone.
