<p>The system is applicable to devices with two cam rests, a slow cam rest and a fast cam rest, provided with a temporising element, and centres its characteristics in the fact that the said temporising element 12, assembled on an oscillating lever 24 moves from the inactive position 13 to the active position 14 by means of the intervention of a selection lever 17 and a clutch 21 which swings about an axis 22 stiffened to the lever 17, whereas the opposite movement, the return movement to the inactive position, is determined by the change in position of the selection lever 17 dragging clutch 21 and which in turn releases the oscillating lever 24, or only by changing the position of the clutch 21. This system, applicable to the field of the household appliances, considerably increases programming capacity.</p> |
