FIELD: engines and pumps.SUBSTANCE: invention relates to peristaltic pump (1) for medium supply through a hose. The pump comprises a housing (2) and several squeezing elements (3), pressing the hose simultaneously with its swaging to the working surface (4a) of the counter-support (4) and thus moving the device in the hose towards the feeding. The distance (d) between the squeezing elements (3) and working surface (4a) of the counter-support (4) is variable. The invention provisions, that the counter-support is designed as a ring segment and comprises a conical mounting surface (4b), which rests on the counter supporting surface (5) of the housing (2). The distance (d) between the squeezing elements (3) and the working surface (4a) of the counter-support (4) can be adjusted by displacement of the counter-support (4) with reference to the housing (2) using the supporting surface (5).EFFECT: maximum compensation of defects of manufacture of the pump and inhomogenuities of the hose material and ensuring of minimum mechanical load of the pump on the hose.14 cl, 9 dwg |
