FIELD: heating systems. ^ SUBSTANCE: suction orifice tube intended for refrigerating device includes suction tube (13) routed parallel to suction tube (13), orifice tube (14) and adhesive tape (19), the middle strip (20) of which is bonded to orifice tube (14), and two side strips (21, 22) enveloping middle strip (20) are bonded to suction tube (13) and covered on suction tube (13) from the side opposite to orifice tube (14). Free end of side strip (21, 22) is sealed with plastic or elastic mixture. Suction orifice tube manufacturing device has at least the first and the second roller (1, 2; 3, 4; 5, 6; 7, 8), the circles of which face each other and form clearance (15, 24); at that, at least on circumferential surface of the first roller (1; 3; 5; 7) there is slot (10, 25) for suction tube for directing suction tube (13) through clearance (24), and at slot bottom (10, 25) for suction tube there formed is slot (12) for orifice tube for directing orifice tube (14) in contact with suction tube (13). ^ EFFECT: use of invention will allow increasing resistance of suction orifice tube. ^ 9 cl, 8 dwg |
