1-10. (canceled)
A method for testing a high-pressure pump, comprising:
- filling the high-pressure pump with a fluid prior to switching it on.
An apparatus for testing a high-pressure pump, comprising:
- a fluid reservoir designed to make a fluid available;
- a low-pressure pump designed to convey fluid from the fluid reservoir into a high-pressure pump to be tested;
- a high-pressure accumulator connected to a high-pressure output of the high-pressure pump;
- a pressure regulating valve designed to regulate pressure in the high-pressure accumulator;
- and
- a control device designed to control the low-pressure pump, the high-pressure pump to be tested and the pressure regulating valve, wherein the control device is designed to control the low-pressure pump, the high-pressure pump to be tested and the pressure regulating valve in such a way that the apparatus causes the high-pressure pump to fill with a fluid prior to switching it on.
