A machine for making ice-cream and similar cold products is described, which has a freezing container insertable in and removable from a substantially cylindrical cooling chamber. The chamber is elastically-deformable and has a circular cross-section that is not completely closed on itself due to the presence of a passage. The passage is closed by a pair of shields and by a substantially bellows portion of elastically yielding and thermally insulating material. In this manner, a better thermal efficiency of the machine is obtained.

A machine for making ice-cream and similar cold products, comprising: a cooling chamber formed by a substantially cylindrical cooling coil, said coil being formed by a plurality of lengths of tubing connected together in series by means of two manifold bodies which are spaced apart in a circumferential direction and define an axially extending passage therebetween, a substantially cylindrical elastic sheath, with an axially extending discontinuity facing said axially extending passage, externally surrounding said cooling coil, a freezing container insertable in and removable from said cooling chamber, two plate-like shields each secured to a respective manifold body and circumferentially projecting towards one another in said axially extending passage, a layer of elastically yielding and thermally insulating material interposed between said cooling coil and said elastic sheath, said layer including a bellows portion extending inside said passage between said plate-like shields and said sheath.
