  • Patent number: 10900478
    Abstract: A pump diaphragm for a diaphragm pump for conveying a fluid includes a solid core with a connection device for a drive rod of the diaphragm pump, and a plate-shaped elastic diaphragm body made of rubber having a peripheral clamping edge. The solid core is embedded at least partially in the diaphragm body and the solid core is produced from a thermoplastic and forms covalent bonds with the elastic diaphragm body made of rubber without adhesive. For this purpose, the thermoplastic, for example polyamide 612 or polyphenylene ether, and the rubber, a periodically cross-linked rubber such as EPDM, are selected in such a way that they are covalently cross-linked with one another at the boundary layer. In this way, a bonding layer that is susceptible to weakening or destruction is not present between the core and the diaphragm body.

  • Patent number: 10830184
    Abstract: A control diaphragm for controlling fuel supply in a carburetor of an internal combustion engine includes a functional region enclosing a sensing region concentrically and a peripheral fastening border for fastening the control diaphragm in the diaphragm carburetor. The control diaphragm closes a control chamber of the diaphragm carburetor and is operatively connected via the central sensing region to a control lever in the control chamber and senses the axial deflection of the sensing region in a manner dependent on operation-induced pressure change in the control chamber. The control diaphragm consists in one piece of temperature-resistant and fuel-resistant, non-elastomeric plastic and the functional region is configured by way of a multiplicity of concentric corrugations. The outermost corrugation directly adjoins the fastening border, and the radius of the outermost corrugation corresponds substantially to the radius of the control chamber.

  • Publication number: 20200307065
    Abstract: The invention relates to a method for forming a dimensionally stable three-dimensional shape into a sheet-like substrate (3) of thermoplastic material comprising the steps of: a.) providing a mould including a first die (1) with a first template surface (11) for contacting an upper surface (31) of the substrate (3) and a second die (2) with a second template surface (21) for contacting a lower surface (32) of the substrate (3) opposite the upper surface (31) of the substrate (3); each template surface (11, 21) having an inverse of a desired shape to be transformed to the upper and lower surfaces (31, 32) of the substrate (3); and at least one of the first die (1) and the second die (2) being transparent to electromagnetic waves of a predetermined wavelength; b.

  • Patent number: 10233870
    Abstract: A control diaphragm for controlling a fuel feed in a diaphragm carburetor of an internal combustion engine, includes a central, substantially flat feeling region, a functional region circumferentially extending around the feeling region in a concentric manner, and a peripheral fastening border for fastening the control diaphragm. The control diaphragm closes off a control chamber of the diaphragm carburetor in a sealing manner in the installed state and is operatively connected by the central feeling region to a controlling lever of the diaphragm carburetor arranged in the control chamber, which controlling lever feels the axial deflection of the feeling region in accordance with an operating-related pressure change in the control chamber.
