Abstract (en)

[origin: WO8502659A1] Improvement to pneumatic sensors for the control of pneumatic cycles wherein a fluid jet pump is supplied at the inlet by a compressed air circuit and is connected at the outlet to a nozzle the stopping of which causes a pressure rise in the fluid jet pump, said rise being used as a control signal of a pneumatic component. The space (4) comprised between the jets (2, 3) of the fluid jet pump is connected on one hand to an outlet orifice (14) emitting the control signal and on the other hand to an air vent valve (13b) which, open during the ejection escape, lets the atmospheric pressure into the space (4), the outlet (14) and the conduit (15) preventing the formation of a depression, and which is closed during the obturation of the escape. The invention is used for the control of pneumatic cycles.
