Use the frontal algorithm for meshing that seems to solve the problem.
You can add the option in your geo file:
Mesh.Algorithm3D = 4 ;

Dear all,

I can not understand why the volume(1) in the attached filed is not the one I am expecting to define:
it should be the union of the three extruded quarter of circle and of the part of the ball.

When commenting the current surface(1) and uncommenting all the other things, everything is ok.

Maybe it is because of an orientation problem, but I've checked twice, and this does not explain that doing the union of the four volumes works perfectly.

I thank you for all your great work, and thank you in advance for your answers,

Best regards,

Alex
