<p>The device has penetration spikes (1,2) diametrically opposed on an axis, in which two flow channels (12a,12b,13a,13b) are available. The two spikes evolve into a rotation symmetrical body (3,4), the bodies being centrally insertable one in the other. The one flow channel guarantees in an axial direction a straight-lined through-flow, whilst the other flow channel, which in the area of the point of the penetration spike has a capillary-type narrowing, is formed as recesses (14,15) between the two penetration spikes within the rotation-symmetrical bodies. <IMAGE></p> |
