We introduce a bi-Hamiltonian hierarchy on the loop-algebra of\mathfraksl(2)\mathfrak{sl}(2) endowed with a suitable Poisson pair. It gives rise to the usual Camassa–Holm (CH) hierarchy by means of a bi-Hamiltonian reduction, and its first nontrivial flow provides a three-component extension of the CH equation.
