| Abstract:
The object of this invention is to produce an injector of plain construction, and capable of automatic action that will start in operation, lifting the water to itself, if necessary, simply upon the admission of steam, and without any further manipulation or adjustment of valves or cocks, which would require the attention of a skilled attendant, and also so arranged that if its action becomes interrupted it will readjust itself to its proper work again, and so continue as long as steam is supplied and there are no foreign substances to obstruct its operation. To accomplish this it is necessary to have one apparatus which will draw the water into the injector and deliver it with some force and great regularity to another apparatus that forces it to the place of final destination, and they must be so arranged and constructed that the second shall in no way at any time interfere with the first so as to prevent it from drawing the water into the injector, and also so that the second, when operating, shall receive the water delivered into the injector, by the operation of the first apparatus; and it tis also further necessary to provide a vent or outlet for the escape of the steam and water (luring the preliminary action of the injector without passing through the second apparatus, and to make the operation of the injector automatic this outlet must be fitted with a valve so arranged that it will close when the action of the injector is established and not before, and will remain closed so long as such action continues, but when such action is broken will open again to allow the injector to repeat the preliminary actions that go to produce its perfect working. Injectors have been made containing two sets of apparatus for the purpose indicated; but so far as I am aware their construction is such that when the injector has to lift its supply of water the second will not start in operation if steam is admitted-to both at the same time, it being necessary for the apparatus that draws the water into the injector to be first put in operation and the water made to cover the second apparatus before the latter is started. This renders it necessary to have separate valves for letting on the steam to each, and complicates both the construction and operation of the injector, and requires skilled attention and manipulation, which I obviate. I am also aware that single-jet injectors have been made in which a valve fitted to the vent or outlet, commonly called the " overflow", has been closed automatically; but in such cases it has been done in either one of two ways—first, by the inward suction of the injector that may sometimes be established at the overflow, owing to an insufficient supply of water, or other imperfections in the working of the injector; but such closing is only to prevent air entering, and does not in any way prevent the escape of water when it is present at that point ; second, by the pressure of the water in the injector upon the valve itself to close it when the steam thereof is released by the raising of the check-valve; but such valve must remain closed until the check- valve again presses it open, and as the pressure upon it must at all times, while steam is turned on the injector, be considerable, it will lose its automatic action unless the check-valve is carefully arranged to prevent any free escape of water around it, and it will then only regain it when the steam is turned off. In my invention the closing of the valve by the device herein shown prevents all ingress or egress of water or air at that point, and whenever the injector ceases to work there is nothing to prevent the check-valve returning to its seat, when all the pressure of the water or steam in the injector will press up)on the valve and its attachments to open it.
Claim:
In a steam-injector, a water-inlet port opening into and an overflow-port opening out of one and the same chamber. |
