This invention relates to valves for vacuum tanks, and has for its primary object to provide a very simple valve construction for vacuum gasoline supply systems such as are ceinmonly used. upon motor vehicles.
It is the purpose of mypresent improvements to provide'a valve for such vacuum systems which can be readily removed without necessitating detachment of the vacuum tank cover for the purpose of inspection and cleaning. My detachable valve unit also obviatestlie necessity of die casting valve seats in the tank cover which frequently work loose and thereby render the system inoperative.
1t is also an object of my present improvements to provide a 'removable vacuum valve designed for use in connection with a well known and widely used vacuum gasoline system without necessitating any material changes therein, and which is of such a construction thatsaid valve will be positive and' reliable in its functional opeiation and capable of manufacture at comparatively low cost.
Vith the above and other object-s in view, the invention consists in the'improved valve for vacuum systems and in the form, construction and relative arrangement of its several parts as will be hereinafter more fully described, illustrated in the accompanying drawings, and subsequently incorporated in the subjoined claims. Y
In the drawings, wherein I have illustrated o-ne simple and satisfactory embodiment of f the invention, and in which similar reference characters designate corresponding parts throughout the several viewsff Figure 1 is a fragmentary vertical section through the gasoline receiving `tank and float chamber of a vacuum feeding system of well known type showingthe saine provided with my improved valve;
Fig. 2 is an enlarged vertical sectional view through the improved valve showing the vacuui'n duct closed and the air inlet passage open, and h Fig. 3 is a similar view showing the air inlet passage closed and the gasoline inlet duct or port open.
Referring in detail to the drawing wherein I have illustrated a portion of the Stewart vacuum gasoline system with which many well known makes of motor vehicles are equipped, 5 designates the tank to whicli'the gasoline is supplied from a vacuum chamber 6 enclosed within the upper end of said tank. The usual connection, (notshown) is provided between tlie lowerend of the tank 5 and the carburcter of the engine.
The upper end of the vacuum chamber 6 is closed by a suitable cast metal cover 7 through which by the pipe connection 8, communidation is established between the vacuum cha-inbcr and a fuel suppl tank on the vehicle.
The cover 7 is a so formed with an upstanding internally threaded boss 9 toreceive the externally threaded end of a valve body 1G. acentral longitudinally extending air passage 11, the upperend of which is diametrically enlarged as at 12 to provide a seat 13 for a gravity seated valve ball 14. Above the seat 13, the valve body is reduced in diameter. as at 15 and provided with a plurality of radially disposed air inlet ports 16 communieating with the upper eiid'flQ of the air passage. 'ljhe upper end of said passage is closed by an internal centrally located threaded stud 18 formed upon a cap 17, said stud being engaged with internal threads ony the upper reduced end 15 of the valve body. By vertically adjusting this cap, the inner end of the cap wall may be positioned with relation to the air inletports 16 to impede, to any desired extent the inflow of air therethrough.
At oneside k,of the central air passage 11, the valvebody 10 isalso provided with a longitudinally extendingiduct 19, the upper end of which is extended laterally and opens through a nipple 2O `formed on the valve body i to which the pipe or tube leading to the intake manifold of the vehicle motor is adapted to be connected; The duct 19 opens at its lower'end into the vacuum chamber 6 at one side of a reduced longitudinal extension 21 formedv on `the lower end of the valve body, said extension terminating in an annular flange 22. i
A float actuated rod 23 kextends upwardly into the air passage 11 and normally has its upper end positioned adjacent the valve ballv 13 as shown in Fig. 3. Below the valve body a member 211 is fixed upon this rod and has an upstanding annular flange surrounding the flange 22 on the valve body, said member 24 carrying stop screws or pins 25 toengage the upper side of the flange 22 and thereby Ylimit the downward gravity move- This valve body is formed with
