Abstract:
The device includes a membrane slidably mounted in a metering chamber, the membrane including a first sealing element forming a check valve, and a second sealing element enabling the membrane to slide in a leaktight manner relative to the metering chamber. The first and second sealing elements are made of a material that is relatively flexible, the membrane also including a rigid portion made of a material that is more rigid than the material of the first and second sealing elements.
