Automatic switching device for energizing rotary commutators in a dish-washing machine

摘要

An automatic switch device is described for alternately supplying water to the two supply pipes of the rotary manifolds provided with spray nozzles in a dishwashing machine.;The device is housed entirely within the water supply pipes and does not require a control outside of this pipe to effect the switching, being driven by the water flowing in the pipe to rotary manifolds by means of a turbine which rotates to transmit motion, through a gear wheel rigid therewith, to a ring gear rigid with a diagonal, elliptical vane which rotates to obstruct the passage of water to one of the two pipes and operates in such a manner as to switch from one pipe to the other.;The presence of the ring gear is necessary to adjust the number of revolutions of the turbine (determined by the pressure of the water) to the desired frequency of switching.;(Figure 1)
