<p>A description is given of a device (1) for the measured dispensing of detergent and for the admission of washing water, timed by means of a timer, in a dishwater whose operation is exclusively hydraulic, comprising a measuring dispenser (2) with a membrane (3) for drawing in the detergent, the membrane in this equipment being operated by the pressure exerted on it by the washing water passing through a portion of the inlet tube (4) which the said membrane (3) faces. In the device (1) in question, downstream of the said portion of the inlet tube (4), there is formed a constriction of the cross section (5) capable of generating a predetermined hydraulic pressure upstream of it, and therefore in the said portion of the inlet tube (4), this pressure action on the surface of the aforesaid membrane (3), and the detergent drawn in by the measuring dispenser (2) being introduced by this device into the said constriction of the cross section (5) or into its proximity.</p> |
