Brew unit - mouting pieces

I've just cleaned my Nespresso but during drying process, two pieces has been removed from brew unit. I'm sure that the little plastic pipe is from the brew unit but have a doubt about the little black plastic piece with the copper spring.

Does anyone knows how to mount these pieces into the brew unit please ?

As you can see here, the brew unit piece (I've unmounted all the parts after the pieces came out of here) and the two little pieces

And here is the hole where the one or two pieces came from

These parts are the non-return valve of the brewing unit. It ensures that water flows only into the brewing unit, but not out the wrong way back into the water hose.

The black pin with the spring and also the little pipe part belong in the hole at the back of the brewing unit, where the water hose enters the brewing unit.

I am referring to the hole which can be seen in the center of your second photo.

First, put the black pin (with the spring around it) into that hole, holding it by the bigger end, and its smaller end facing downwards into the hole.

Then, put the little pipe part into that hole. Be aware it has got two different side: One is cylindrical inside, the other is conical inside.

The conical should face down, i.e. go in the hole first. So that afterwards, when you put the water supply hose it it, it will be inserted into the cylindrical end of the little pipe part.
