Abstract
A fluidic device comprises an inlet and an outlet connected by a body forming a channel between the inlet and the outlet. The fluidic device further comprises a non-return valve shaped to prevent a fluid from passing from the outlet to the inlet, and a flow restrictor shaped to allow a fluid to pass from the inlet to the outlet at a first flow rate when the differential pressure between the outlet and the inlet is below a threshold(S). Fluid passes from the inlet to the outlet at a second flow rate, significantly lower than the first flow rate, when the differential pressure between the outlet and the inlet is above the threshold.
