Publication number: 20150330518Abstract: The invention relates to a membrane valve (10), in particular for fluid media, comprising a valve body (20), a membrane (22), a pressure piece (44), and a drive (14) for the pressure piece (44). The membrane (22) is coupled to the pressure piece (44) by means of a connecting element (24), said connecting element (24) having a wall (56) which projects from the membrane (22) in the direction of the pressure piece (44) and on which a laterally protruding latching hook (58) is provided on one side and a free space (50) is provided on the other side such that the wall (56) can be deflected in order to connect the latching hook (58) to a corresponding receiving portion (63) on the pressure piece (44). A stationary pin (74) is provided which engages into the free space (50) when the membrane (22) is raised from the valve seat (32) of the valve body (20) and which protrudes out of the free space (50) when the membrane (22) is resting on the valve seat (32).Type: ApplicationFiled: October 30, 2013Publication date: November 19, 2015Inventors: Fritz Müller, Raphael Flaig

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: 7360450Abstract: A flowmeter for measuring a flow velocity of a fluid in a pipeline includes a measuring tube having opposite ends. Two ultrasonic transducers are disposed respectively at the opposing ends of the measuring tube, and two connection pipes are provided for attachment of the flowmeter to the pipeline and extend in axial relationship to the pipeline.Type: GrantFiled: August 31, 2006Date of Patent: April 22, 2008Assignee: GEMÜ Gebrüder Müller Apparatebau GmbH & Co. KGInventor: Fritz Müller

Patent number: 7273072Abstract: A valve body for a valve assembly includes a main passageway in which a primary valve is received which has a weir constructed to define a valve seat and to interact with a valve element in the form of a diaphragm. Integrated in the valve body is a secondary valve having a weir which defines a valve seat and interacts with a second valve element in the form of a diaphragm. The secondary valve is constructed to allow establishment of a fluid communication upstream of the valve seat of the primary valve between the main passageway and a branch line, via which a medium sample can be extracted and/or steam and/or condensate can be, optionally, released.Type: GrantFiled: May 10, 2005Date of Patent: September 25, 2007Assignee: 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. KGInventors: Fritz Müller, Klaus Heger

Patent number: 4795694Abstract: A method for the manufacture of fine structures for semiconductors were in a photographic structuring is carried out on both sides of a smooth, non-stressed metal tape. The tape is etched from both sides. A single sided metal deposition than takes place by means of a float type electroplating. Stabilization of the fine structure is achieved by depositing a lacquer or resin by an electrophoretic deposition or by electro-immersion lacquering. The insulator carrier is applied as one of the final steps of the process.Type: GrantFiled: May 21, 1987Date of Patent: January 3, 1989Assignee: Siemens AktiengesellschaftInventors: Alfred Groeber, Hans Hadersbeck, Fritz Mueller, Hubert Zukier, Hans J.

Patent number: 4715580Abstract: A swinging device for controlling opening and closing of a shut-off valve or the like includes an oscillating crank which is pivoted with its one end to a nut reciprocating on a spindle driven by an electromotor via a gear transmission. The oscillating crank swings between two end positions and is provided with an elongated slot in which a prolongation of a coupling member projects in shiftable but non-rotational manner. In both end positions of the crank which correspond to the respective opening position and closing position of the shut-off valve, a maximum torque is exerted on the switch shaft because the distance of the point of articulation of the crank to the nut from the rotational axis of the switch shaft is at a maximum.Type: GrantFiled: February 17, 1987Date of Patent: December 29, 1987Inventor: Fritz Mueller

Patent number: 4705061Abstract: A drive mechanism for a spindle of a valve includes an electromotor with subsequently connected gear transmission which are arranged laterally offset to the axis as defined by the spindle to allow the latter to move in axial direction unimpeded from electromotor and gear transmission and to be adjustable to arbitrary strokes. The spindle is actuated by a nut which cooperates with the gear transmission and is locked in its quiescent stage to prevent a rotation thereof. The gear transmission is also manually actuatable via a crank handle whose grip portion in addition serves also a viewing glass when attaching the crank handle in elongation of the spindle at an appropriate location of the housing.Type: GrantFiled: May 19, 1986Date of Patent: November 10, 1987Inventors: Fritz Mueller, Lothar Pienta
