Abstract

The displaceable cone (3) works in conjunction with a tubular seat (2), the throughflow channel of which has a wall (8) which is rotation symmetrical in relation to the movement axis of the cone, and has a successively reducing throughflow area. - The seat (2) has an outer wall (9) parallel with the displacement axis (5), and both come and seat comprise a porous, sound-damping body pressed out of unburnable fibre material.
