  • Thermostatic working element and method for manufacturing a thermostatic working element
    Publication number: 20110197579
    Abstract: A thermostatic working element has a housing that contains an expansion material, the volume of which is dependent on temperature, and which is used as a means for expelling a working piston. An additive of ground natural graphite is blended with the expansion material.

  • Control valve, especially for an internal combustion engine, for the controlled recycling of exhaust gases
    Patent number: 6726174
    Abstract: The invention relates to an exhaust gas control valve with a first valve part (14) and a second valve part (44), which rest on one another with one side (17, 46), the valve parts (14, 44) in each case having passages (14, 45) and being rotatable relative to one another between an open position permitting the passage of exhaust gases and a closed position, blocking this passage. Webs (21 to 23), which protrude on one axial side of the first valve part (14), surround the openings (15) and, with their free narrow surfaces, form supporting surfaces for the second valve part (44), which is constructed flat on its side (46) facing the first valve part (14) and essentially rests with this surface on the narrow surfaces of the webs (21 to 23) and slides during the relative rotational adjustment, extend along the boundary edges (18 to 20), surrounding the passages (15, 45) of the first valve part (14).
