FIELD: technological processes.
SUBSTANCE: in design of casing for device with working medium under pressure there is filter (12) which forms unit part with working medium under pressure, device contains first body (20), unit of casings (22) connected to lower part of first casing (20) and filtering unit (24) mounted inside unit of casings (22). Unit of casings (22) consists of external casing (40) which is made in the form of cylinder with bottom made from transparent material, and inner casing (42) fitted inside outer casing (40). Besides, when inserting unit of casings (22) in mounting opening, which is open in lower part of first casing (20), and rotating unit of casings (22), projections (58) and fixing partitions (56), available on outer peripheral surface of unit (22), are engaged with support elements arranged in mounting opening, thus connecting unit of casings (22).
EFFECT: increased service life of casing.
