The machine (10) has two gear wheels disengaged with each other. The tooth edges are surrounded by a main body (31) and lids with a low pressure connection (32) and a high pressure connection (33). Each gear wheel has bearing pins, which are rotatably mounted in bearing bodies (50). The bearing bodies are slidingly movably accommodated in the main body relative to rotational axis of one of the toothed wheels. A piezo film (70) is arranged between the bearing bodies and the main body. A sensor directly measures a force acting on the gear wheels. |
