<p>The invention is directed to a balanced pressure steam iron having a closed water tank and steam generating soleplate with control means to start and stop a metered flow of water. It has pressure balancing means connecting the steam generating soleplate and tank and a power spray means connected to the tank. In this conventional iron the invention provides an improvement in means to control pressure in the tank by supplying a coverplate overlying the soleplate to define steam passages therebetween and pressure ocntrol is provided by a continuously open pressure controlling conduit through the coverplate, the conduit containing an orifice and being formed to repel foreign particles whereby the single continuously open conduit controls both pressure within the iron and vents the iron for filling or emptying when upended.</p> |
