摘要：

Friedmann Robertson Walker cosmological models with bulk viscosity are constructed in the scale covariant theory of gravitation. A new class of solutions for the field equations of the model is found by applying variable deceleration parameter. Some physical models of these solutions are briefly discussed in this paper.
