FIELD: engines and pumps. ^ SUBSTANCE: filter incorporates a housing accommodating tubular filter elements, a lower chamber with a contaminated medium inlet union and an upper cover with a purified liquid discharge union. The filter elements are arranged between the upper plate and the lower plate rigidly fitted on the rotary shaft mounted in the plates coaxial holes. The upper plate is furnished with blind holes to axially lock the said filter elements. The lower plate is furnished with through step-wise holes. The quantity and mutual arrangement of the said holes correspond to those of the filter elements, which, assembled with the shaft and the plates, make a rotary drum. The shaft supports a star-like filter elements positioning unit representing a plate with teeth the number and arrangement of which is subject to the number and arrangement of the filter elements. The upper cover is furnished with a pressure pickup and a support of the star teeth position pickup, its sensitive element being arranged in one horizontal plane with the said star and facing the star side surface. The lower chamber incorporates a re-washing union with a solenoid and pressure pickup connected thereto. ^ EFFECT: filtering process automation, higher efficiency of filter element recovery, longer life and lower costs. ^ 8 cl, 6 dwg |
