We report the detection of 3 new planetary companions
orbiting the solar-type stars GJ 3021,
HD 52265 and
HD 169830 using radial-velocity
measurements taken with the CORALIE echelle
spectrograph. All these planetary companions have longer orbital
periods than the 51 Peg-like objects. The orbits are fairly
eccentric. The minimum masses of these planets range from 1 to
3.3 
. The stars have spectral types from F8V
to G6V. They are metal-rich. We also present our radial-velocity
measurements for three solar-type stars known to host planetary
companions ι Hor (HD 17051),
HD 210277 and
HD 217107.
