A second cylindrical cavity is fluidly connected and coaxial with the first cylindrical cavity. The second cylindrical cavity has a smaller diameter than the first cylindrical cavity. A second opening is also provided in the solid body which opens into a third cylindrical cavity. The third cylindrical cavity has a diameter that is larger than the diameter of the second cylindrical cavity but smaller than the diameter of the first cylindrical cavity.
