Abstract

Dispenser of auxiliary fluids in washing machines characterized by being constituted of two bodies linearly superimposed and joined by their bases on an intermediate sealing disk traversed axially by the rod of an acting piston in the lower body while the upper body comprises the mechanism of action on the plunger; whose upper body connects its free base with a branch derived from the general direction of the rinse water while the lower filled with dosing fluid involves two inverse action respectively injection and aspiration valves the first of which is connected by another branch to the general operation of the rinsing water closing the bypass and the second to a container containing the auxiliary fluid whose injection and suction valves;. Present a simultaneous working system respectively of closing and opening and correspondingly of reverse work under a differential pressure in relation to the upper external and vice versa respectively derived from the embolar action in the fluid sinus in which they are submerged, also having an externally operated screw with internal rod in sealing needle of the inlet conduit, the injection valve constituted in dosage regulating element; and because the upper body is subdivided into two chambers coupled together by circular external extensions and parallel to the bases of the cylinder comprises a laminar assembly in a single mobile body parallel to the bases and joined in its center perpendicular to the plunger rod constituting the drive mechanism for the same whose laminated assembly is composed of a discoidal membrane whose circular crown is trapped between the circular expansions of the chambers and whose central zone is comprised between a discoidal plate and the bottom of an open cylindrical box. Inverted to the outer envelope constituting the said set the receiver of the pressure exerted by the liquid stream of rinsing water determining the advance of the piston in the cylinder as a recoil spring contouring the stem and seated on the laminar assembly and the intercilºndrico unión disc constitutes the element or of recovery of the piston to its initial position when the pressure of the rinse water disappears.
