  In order to further test our hypothesis that jets and disk around compact
accreting objects are symbiotic features we investigate the newly discovered
superluminal galactic radio jets GRS 1915+105 and GRO J1655-40 and the two
famous galactic radio jets 1E1740-2942 and SS 433 within the framework of our
couple jet/disk model developed initially for active galactic nuclei (AGN) and
the galactic center source Sgr A*. By comparing the ``disk'' and radio core
luminosity of those galactic jet sources with our model prediction we can show
that they can easily be understood as AGN-like jets where the accretion power
onto a central compact object is scaled down by several orders of magnitude.
The total power of the jets must be comparable to the disk luminosity - at
least for the superluminal sources. To broaden our view we also shortly discuss
the situation in other galactic flat spectrum radio source associated with
compact objects -- the X-ray binaries Cyg X-1, Cyg X-2, Cyg X-3 and Sco X-1 --
where a jet origin has been proposed earlier on theoretical grounds. In an
disk/radio luminosity their radio cores also fall within our model prediction
for scaled down radio loud and radio weak AGN-jets. Taking all sources together
and comparing their L_disk/radio ratio we find an indication for a similar
radio loud/radio weak dichotomy as found earlier for quasar radio cores,
however, a larger number of galactic jet sources is needed to confirm this
trend.
