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