The invention relates to a device (8) for arranging in a liquid conduit for limiting a liquid flow in this conduit, which device comprises a base part (9, 10) with a through-flow opening and a closing part which is arranged on the base part via spring means and which is displaceable with at least a substantial axial component for partially closing the through-flow opening against a closing surface (13) on the base part, wherein the device can be fixed at a fixed position i n the conduit by means of fixation means such that the liquid can pass through the device only via the through-flow opening and wherein th e base part and the closing part (13) are arranged relative to each other such that in a rest position defined by the spring means a gap (1 2) is formed between the base part and the closing part, which gap is made smaller counter to the spring action by bending under the influence of the liquid pressure difference over the device.
