Abstract
The invention relates to a backflow preventer () integrateable into a gas or liquid pipeline (). The inventive backflow preventer consists of a closing body () which is embodied in the form of a hollow body which is open on a drainage side thereof and defines a passage channel () between itself and the central counterpart () opposite thereto. Said closing body () is displaceable by a flow medium flowing through the passage channel () in a flow direction (Pf) from a sealing contact thereof with said counter part () of the closing body to the open position thereof against the opposing force of elasticity and o r stability thereof. Said backflow preventer () is easily producible even with a small number of components and is characterised by a high flow and low pressure loss.
