Resum:	Let (X, M,ų) be a σ-finite measure space, Lø - Lø (X, M, ų) an Orlicz space associated to an N-function ø and let T : Lø→Lø be a linear operator with a fixed point h ≠ 0 a. e . , such that [fórmula matemàtica inclosa a l'article] and it is either a II 1 -contraction in Lø ∩ L1 or a II II∞ . -contraction in Lø ∩ L∞ The main result of this paper is that for a wide class of N functions ø 0, the ergodic maximal operator associated to T is bounded in L ø. Moreover, for every f € L ø we have the almost everywhere convergence and the norm convergente of certain weighted averages which include the Césàro averages.
