Abstract

Abrupt action device for programmable control elements, which is specially designed to establish the step-by-step rotation of a disk or drum of cams that sequentially drives a series of contacts, through which the different phases of work of a machine, such as a washing machine, a dishwasher or the like, is essentially characterized in that the transport element, displaceable tangentially with respect to the cam disk or drum, intended to cause the unitary drag of the teeth established on the periphery of said disc or drum and displaceable in the alternative direction by a cam driven by the geared motor of the programmer, incorporates a rod that laterally adapts a pivoting lever at a point very close to the pivoting axis of said lever, having provided that such lever incorporates a considerable concentration of mass, in at least, a point considerably away from its tilt axis, t all this in such a way that the rotation of the load cam causing the retraction of the transport element determines the tilting, through the stem associated with said element, of the lever against the tension of the spring that assists it, while when the maximum dimension of the cam is exceeded and the staggering established in it is reached, said recoil spring causes the tilting in the opposite direction of the lever, with a great inertia, dragging this to the transport element through the stem associated with the lever. The latter, with a reduced speed and also a reduced kinetic energy. (Machine-translation by Google Translate, not legally binding)
