Abstract
A diaphragm poppet valve has a control diaphragm which is resilient in shape and separates a control chamber from a working chamber. The control diaphragm is designed as a single piece on the side thereof facing the control chamber or the working chamber of the diaphragm poppet valve with a hollow portion and on the side thereof facing the working chamber with a diaphragm valve seat. The interior of the hollow portion issues into the diaphragm valve seat and the hollow portion is connected to a fluid channel in the diaphragm poppet valve. The diaphragm poppet valve is easy to clean because the interior of the hollow projection and the diaphragm valve seat formed by the control diaphragm can easily be flushed.
