AN INTEGRATED ASPIRATOR WITH VACUUM SENSOR

Aspirators and Vacuum sensors are an integral part of Brakes system. Aspirators help in boosting up the vacuum by speeding up the air speed through an orifice by Bernoulli's principle. This works by supplementing the Engine vacuum with an air flow from the AIS system. Some of the aspirators are inline while others are inbuilt into the booster. Vacuum sensors on the other hand sense a loss of vacuum and use hydraulics to provide failed boost assist. In addition vacuum sensors can be used for various other functions like providing vacuum only when needed. In most cases, the vacuum sensors and aspirators are separate entities. They are typically plugged into different ends of the booster. For this invention, it was felt that it is possible to combine both of them. This helps in optimizing the package space and reducing labor time in the plant. In the diagram below the old method shows an aspirator which is plugged to the booster on its own and the vacumm sensor is somewhere else on the booster shell. The New method shows the integrated sensor with the aspirator.

     Conclusion By combining the aspirator and vacuum sensor, it is possible to improve package space and reduce labor time.
