A new type of cellular automaton (CA) is discussed. This CA is 1+1 dimensional and 2-valued, and any state produces only solitary waves. When the solitary waves interact one another, they preserve their identities and the only effect left after the interaction is a shift of their orbit. Any initial state can be decomposed into the solitary waves. Moreover, an infinite number of conserved quantities exist. Therefore, the CA may be considered to be a simple soliton system. A class of multi-valued CA's are also proposed. They are an extension of the above 2-valued CA and have many properties of soilton system.
