Optical sensor has translucent element, which is arranged in mouth of channel open out in pressure chamber arranged in wall of pressure chamber and translucent element is arranged at support surface

摘要

The optical sensor (1) has a translucent element (13) for analysis of position or motion of a component (6), which is arranged in a pressure chamber (3) filled with a fluid or with a fluid-gas mixture or with a gas, particularly in a jet pump of an injection system of a vehicle. The translucent element is arranged in a mouth (10) of a channel (2) open out in the pressure chamber arranged in wall (8) of the pressure chamber. The translucent element is arranged at a support surface (12) for receiving active forces for the pressure chamber over the translucent element firmly.
