Patent number: 7458560Abstract: A diaphragm valve includes a valve body defining a passageway constructed to form a valve seat, and a diaphragm. A compressor moves the diaphragm between a closing position in which a flow of fluid through the passageway is barred as the diaphragm is caused by the compressor to seal the valve seat, and an open position in which at least part of a cross section of the passageway is bounded by the diaphragm to thereby enable a flow of fluid through the passageway substantially without narrowing the cross section of the passageway.Type: GrantFiled: April 10, 2006Date of Patent: December 2, 2008Assignee: GEMÜ Gebrüder Müller Apparatebau GmbH & Co. KGInventor: Fritz Müller

Patent number: 6988419Abstract: A flowmeter includes a floating body which floats freely in a stream in a measuring tube, and is acted upon by a flowing force, buoyancy and a weight. In order to generate a counterforce, a measuring spring is fixedly connected to the floating body. The floating body is preferably self-stabilized through a selection of corresponding geometrical relationships. The measuring spring can optionally be rotatably supported on the floating body and/or the measuring tube. The floating body is suitably made of light weight plastic material, so that the density (mass/volume) of the floating body matches the density of the flowing medium.Type: GrantFiled: November 19, 2002Date of Patent: January 24, 2006Assignee: GEMÜ Gebrüder Müller Apparatebau GmbH & Co.
