摘要
The pre-timed distribution unit (1), in particular for internal combustion engines, is constituted by a first sprocket wheel (2), and a second sprocket wheel (3) with a plurality of sprocket sets, a multiple-link chain (4) taut between said sprocket wheels and defining a space inside which a guide shoe (5) is housed, which is constituted by at least a plate-shaped structure provided with guides radiused by a first and a second mating, trueing circumferential edges (7, 8). In an alternative form of practical embodiment, the unit comprises a guide shoe whose guides are associated with enlarged, laterally protruding portions.
