摘要: Disclosed is a flow force compensating spool valve having a flow force compensating protrusion ring at a supply channel of a sleeve on an outer circumference portion of a spool rod, and a hydraulic valve, a pneumatic valve, a three-way valve, and a four-way valve using the spool valve, in which the flow force can be compensated by a simple structure change of the spool without changing a structure of the sleeve.

摘要: A method is proposed for characterizing a totality of particles (318). The method can be used in particular for charactering microparticular or nanoparticular aerosols. The method comprises the following steps: a) in a classification step, a class of the totality is selected, wherein the particles (318) of the selected class have a prespecified mobility dm; b) in a counting step, a number N of the particles (318) of the selected class is determined; c) in a charge determination step, a charge Q of the particles (318) of the selected class is determined; and d) in an evaluation step, at least one morphological parameter is determined from the charge Q, the number N and the mobility dm, wherein the morphological parameter comprises at least one item of information about an agglomerate state of the particles (318).
