Context. The statistical properties of binary stars are clues forunderstanding their formation process. A radial velocity survey was carried onamongst nearby G-type stars and the results were published in 1991. Aims. Thesurvey of radial velocity measurements was extended towards K-type stars.Methods. A sample of 261 K-type stars was observed with the spectrovelocimeterCORAVEL (COrrelation RAdial VELocities). Those stars with a variable radialvelocity were detected on the basis of the P(chi^2) test. The orbital elementsof the spectroscopic binaries were then derived. Results. The statisticalproperties of binary stars were derived from these observations and publishedin 2003. We present the catalogue of the radial velocity measurements obtainedwith CORAVEL for all the K stars of the survey and the orbital elements derivedfor 34 spectroscopic systems. In addition, the catalogue contains eight G-typespectroscopic binaries that have received additional measurements since 1991and for which the orbital elements are revised or derived for the first time.
