ABSTRACT:
Arrangement for controlling and regulating a liquid (2) flowing through a line (3). The arrangement comprises a valve body (9) provided with a press-on or deforming element (11) moveable along the line and designed to cooperate with the said line for regulating the flow of the liquid (2), by means of restriction thereof to varying degrees. In the line (3) there is fitted a continuous hollow element (4) having a number of openings (8) through which the said liquid can flow. The press-on element (11) moveable along the hollow element (4) is designed to press the line (3) against the said element (4). By this means a shifting of the press-on element can be carried out such that an optional area of the openings can be uncovered for throughflow since that part of the hollow element where the said area is located is situated on the outlet side in relation to the press-on element. The openings of the hollow element can be uncovered to varying degrees by means of the press-on element arranged in the valve body, the line being pressed against the openings of the hollow element in such a way that the flow is restricted to varying degrees.
