VALVE WITH MATERIAL HAVING MODIFIABLE DEGREE OF PENETRABILITY

摘要

PROBLEM TO BE SOLVED: To provide a valve to control a passage of particles from a first region to a second region with a less complex arrangement.SOLUTION: The invention relates to a valve 2 for controlling a passage of particles from a first region 6 to a second region 7. The valve 2 comprises a valve material 4 having a modifiable degree of penetrability and a valve region comprising the valve material 4, where the valve region and the valve material 4 are adapted such that the particles have to penetrate the valve material 4 if the particles pass the valve 2 for being transferred from the first region 6 to the second region 7. The degree of opening of the valve 2 can easily be controlled by modifying the degree of penetrability of the valve material 4 by modifying the temperature of the valve material 4. By penetrating the valve material 4, the particles can be separated from other elements such as a fluid containing the particles.SELECTED DRAWING: Figure 2
