 The latice $K(R)$ of all pretorsions of the category $\mathcal{M}$ of left unitary $R$-modules over an associative ring $R$ with unity element is examined and the rings over which the latice $K(R)$ has only one maximal element are described. Some applications are shown too. 

All articles are published in Russian.
