Embodiment Construction

[0110] figure 1 In particular an embodiment of a bimetallic composite system is shown, which is formed from a first part 1 and a second part 2 , wherein the second part extends at least partially through the first part along an imaginary longitudinal axis L of the composite system. as can be obtained from figure 1 As can be seen in , the second part 2 here has an at least partially curved outer surface, in particular configured as a cylinder, which touches flush against the inner surface of the first part 1 in such a way that the first part is at least sectionally at least partially Surrounding the second part, creating a composite system of first and second active surfaces 1B, 2B. In order to increase the fatigue strength of the composite system, in particular to increase the pull-out strength of its second part 2 from the first part 1, the composite system effective surfaces 1B, 2B formed by the surfaces of the two parts, in particular in direct contact, are formed in such ...

Abstract

To improve reliability with respect to fixing of a compression element and its drive motor into a casing, in a hermetic compressor. Since a shape of a welding hole 20 is conical, weld surely reaches aprojection part 17 and prevents defects such as stay of the weld on a surface of a case.

Description

technical field [0001] The invention relates to a vibration-type measuring transmitter of a measuring instrument for measuring a medium flowing in a pipeline. Furthermore, the invention relates to a method for producing such a vibration-type measuring transducer. Background technique [0002] In industrial measurement and automation technology, in-line measuring devices with vibration-type measuring transducers are used for high-precision recording of process variables, especially fluid dynamics and / or rheological measured variables, especially of media flowing in pipelines. Such measuring instruments usually comprise at least one measuring tube which communicates with the pipeline of the transfer medium and vibrates during operation. Examples of structure, function and use of such vibration-type measuring transducers are described, for example, in US-A 41 27 028, US-A 45 24 610, US-A 47 68 384, US-A 47 93 191, US-A 48 23 614, US-A 52 53 533, US-A 56 10 342, US-A 60 06 609...
