Abstract

1. Способный к расширению фильтр, включающий опорную трубу с прорезями и размещенную на ней фильтрующую оболочку из проволоки, отличающийся тем, что фильтрующая оболочка изготовлена из проволочной спирали, спрессованной в толстостенные цилиндры.2. Способный к расширению фильтр по п.1, отличающийся тем, что толстостенные цилиндры состыкованы между собой с помощью кольцевых выступов и ответных кольцевых канавок, сформированных на их сопрягаемых торцах.1. An expandable filter comprising a support pipe with slots and a filter shell made of wire placed on it, characterized in that the filter shell is made of a wire spiral pressed into thick-walled cylinders. 2. The expandable filter according to claim 1, characterized in that the thick-walled cylinders are joined together by means of annular protrusions and reciprocal annular grooves formed at their mating ends.
