For the reduction and throttling of quantities of liquids, especially in outflow fittings, showers, sprays, etc, by means of an elastic component which can be inserted into any pipe cross-section and can be actuated in dependence on pressure and which forms, with a number of slits, part regions which open and close in dependence on pressure. As a result of the closing of the slits, the throughflow cross-section is narrowed and less liquid can flow through.
