Abstract. We consider an asymmetric zero range process in infinite volume with
zero mean and random jump rates starting from equilibrium.
We investigate the large deviations from the hydrodynamical limit of the
empirical distribution of particles and prove an upper and a lower
bound for the large deviation principle. Our main argument is based
on a superexponential estimate in infinite volume. For this we extend
to our case a method developed by Kipnis & al. (1989) and Benois & al.
(1995).
