Abstract

A test stand for testing a fluid injection pump and/or a fluid injector has a device for conditioning a test fluid used for the testing. The device has a tank to accommodate and store the test fluid, a first fluid removal line to withdraw test fluid from the tank and to convey it to the fluid injection pump, and a cooling circuit for cooling the test fluid stored inside the tank. The cooling circuit has a second fluid removal line and a return line. The fluid removal line is to withdraw test fluid from the tank and is connected to a heat exchanger, which cools the test fluid withdrawn from the tank. The return line is connected to the heat exchanger and returns the test fluid from the heat exchanger back into the tank.
