FILTERING APPLIANCE Russian patent published in 2016 - IPC B01D46/24 

FIELD: process engineering.

SUBSTANCE: invention relates to filtration. Claimed filtering appliance comprises body (20) with channels to feed pressurised working fluid therein and to discharge it therefrom, cylindrical jacket (22) with bottom to be coupled with and uncoupled from said body. Note here that the jacket inside communicated with said channels while said filtering unit (24) is arranged inside said jacket. Filtering unit (24) has the filtering element (80) for removal of dust, foreign particles and other impurities contained in working fluid. Filtering element holder (82) and coupling mechanism are meant for connection between the jacket and filtering unit and for adjustment of relative axial shift between the jacket and filtering unit. Coupling mechanism comprises the first coupling element (64) arranged at the jacket exposed end and the second coupling element (94) located at holder (82). The first coupling element (64) and the second coupling element 94 are coupled by fitting the second coupling element (94) from the side of open end in the jacket and joint revolution of the jacket and filtering unit. The first coupling element extends outward radially relative to exposed end while the second coupling element extends radially inside toward the holder.

EFFECT: easy and reliable coupling and removal of the filter.
