Abstract:
This invention relates to a breathing sensing device for detecting a pressure drop due to breathing. The device includes a diaphragm (100) having a first pressure chamber (120) on one side and a second pressure chamber (121) on a second side within an actuator housing. The first and second pressure chambers (120,121) are connected to a system pressure (L1) by flow passages (143, 153) having different cross sectional passage area (Ar, Af) arranged to facilitate detection of a pressure drop due to breathing.
