AIR-VALVE ATTACHMENT FOR CARBURETERS.
Specification of Letters Patent.
Patented Jan. 13, 1920.
Application'filed April 2, 1918. Serial No. 226,308.
To all whom it may concern:
Be it lmown that I, HARRY L. LANE, a citizen of the United States, residing at Venice, in the county of Los Angeles and State of,
"California, have invented a new and useful AirValve Attachment for Carbureters, of
which the following is a specification.
My invention relates to an attachment for carbureters such as are used on internal combustion engines, being more particularly a valve which is placed upon-the air intake of the carbureter whereby the amount of air entering the carburetor is varied automatically.
The principal object of my invention is to provide an attachment of the class described of simple form and construction, which automatically regulates the flow of air to the carburetor and also operates to open the valve in the case of backfire of the enwine.
0 Other objects and advantages will appear hereinafter from the followlng description and the drawings,
Referring to the drawings, which are for illustrative purposes only,
Figure 1 is a vertical sectional view of a common form of carbureter showing an attachment thereon embodying a form of myinvention.
Fig. 2 is an end view of-the attachment shown in Fig. 1, and
Fig. 3 is a cross sectional view 011 line 3 3 of Fig.,1.
The carbureter shown consists of abody 11 having a mixing chamber 12in the bottom of which is formed a well 13 connected by means of a passage 14 with ducts 15 which extend into a float chamber 16 formed in a cup 17 which is held firmly in place on the body of the carburetor by means of a nut 18. 19 designates a common form of float by means of which the height of the gasolene, indicated at 20, is regulated in the float chamber. 1
Formed at the upper end of the passage 14 is a valve seat 22 arranged to receive a needle valve 23 which extends through a cap 24 secured to the upper portion of the body 11, the needle valve being provided with a suitable operating handle 25. 26 designates having openings 48 formed therein.
' a hollow extension formed on the body 11 forming a mixture outlet 27 for the carbureter, which outlet is controlled by means of a suitable valve indicated at 28, the mixture outlet 27 being in open communication with the mixing chamber 12 and being connected in any well known manner with the lntakemanifoldof the internal combustion englne.
30 designates a cylindrical extension formed on the body of the carbureter at .the opposite side of the mixture outletand is provided with an air intake passage 31 which may be manually controlledby a valve 32, the stem 33 ofwhich extends through the extension 30, being provided with any suitable operating means indicated at 34.
: The attachment in the form shown consists of a cylindrical casing or valve body 36,
the inner endof which fits over the end of the extension 30 on the carbureter body, being securely held thereon by means of a suitable screw 37. The valve body '36 is provided with a cylindrical bellied portion is headed over the bars to firmly support the rod upon the same.
Slidably mounted on the rod is a sleeve 44, the inner end of which is turned outwardly forming a circular flange 45 and the outer end is turned outwardly forming a circular flange 46. Pressed upon the sleeve. 44 against the flange 45 thereon is a valve member consisting of a circular plate 47 This valve member 47 is in tight relation with the sleeve44 and movable therewith, as hereinafter more fully described. 50 designates a circular follower plate which is slidably mounted upon the sleeve 44, being elastically held against the valve member 47 by means of a spiral spring 5 1.
The outer end of the spring 51 abuts against a retainer ring 52 which in turn is held upon the sleeve- 44: by means of the flange 4:6. The follower plate 50- is of lesser external diameter than the openings 48 in the valve member 47 thereby permitting air to pass around the follower plate and through such openings 48 in the valve member 47. The sleeve 44 is elastically held in outer position, that is, the position shown in full lines in Fig. 1, by means of a spiral spring 55 which abuts against the flange on the sleeve 44: at one end and at the other end against a circular flange 56 formed on a retainer sleeve 57 This retainer sleeve 57 is mounted on the inner, end'of the rod 42, being held thereon by means of a split ring 58 seated in a groove 59 in the rod 42, the retainer sleeve 57 fitting slightly over the ring 58 to prevent dislodging of the same.
The attachment operates in the following manner:
Assuming that the engine to which the carbureter is attached is not running, the parts are in the position shown in full lines in Fig. lwhere it is to be noted that the valve-member 4:7 is in the inner end of the throat 40, there being a circular space between the outer edge of the valve member and the inside of thethroat leaving a circular air passage therebetween. As the engine is started the pull on the carbureter draws the air through the attachment and through the passage 31 in the carbureter down over thewell 13 where it mixes with the liquid fuel and passes out of the carbureter to the engine through the passage 27. When the engine picks up and exerts greater pull on the carbureter the air entering the throat 40 presses against the follower plate 50, which, being against the valve member 4:7, pushes the valve member 47 against the action of the spring 55 into approximately the dotted line position shown in Fig. 1.
When the valve member 47 is in this position a much greater volume of air is permitted to pass the valve member due to the fact that the valve member when in such open position is in the bellied portion 38- of the attachment, the air passing freely through the air chamber 39 around the valve member 47 It is to be understood that the E position of the valve member 47 is regulated by the pull of the engine on the carbureter thereby automatically varying the volume of air entering the carbureter to meet the requirements of the engine.
In the case of a backfire of the'engine the pressure placed thereby on the carbureter is relieved by a movement outwardly ofthe follower plate 50. This is due to the fact i that the pressure caused by the backfirey exerts itself against the follower plate through the openings .98 in the valve member, such pressure compressing the spring 51, the follower plate moving away from the valve member 47 into the dot and dash line position shown in Fig. 1 where the pressure is quickly relieved through openings 60 in the throat 40, and around the follower plate 50. v
It is further to be understood that the springs 51 and 55 in their action are independent of each other, that is, the spring 51 acts solely against the follower plate and the spring 55' acts solely against the sleeve 44: upon which the valve member 4:? is, fixed.
What I claim is i 1. An air valve attachment for carbureters comprising a cylindrical valve body having a restricted; portion at one end, a rod rigidly mounted in said body, a sleeve slidably mounted on said rod, a valve member secured to said sleeve consisting of a flat circular plate of smaller diameter than the inside of the restricted portion, said plate having openings therein, means for elastically holding said valve member within the restricted portion of the valve body, a follower plate mounted on said sleeve extending partially over the openings in said valve member, and means on said sleeve for elastically holding said follower plate against said valve member.
2. An air valve attachment .for carbureters comprising a cylindrical valve body having a throat portion and a bellied portion, a rod rigidly mounted on said valve body extending into the. same, a] sleeve slidably mounted on said rod, a valve plate secured to said sleeve, a helical spring on said rod arranged toelastically 'hold said valve member in the throat of the valve body, said valX e member having openings therein, a follower plate slidably mounted on said sleeve, and means on said sleeve for elastically holding said follower plate against said valve member partially over the openings in the valve member.
3. An. air valve attachment for carbureters comprising a cylindrical valve body 11 having a throat portion and a bellied portion, supporting means on the outer end of said valve body, a rod mounted on said supporting means extending into said valve body, a sleeve slidably mounted on said rod, 115 a helical spring mounted on said rod adapted to elastically hold said sleeve against said supporting means, a valve plate having openings therein mounted on said sleeve, a follower plate! slidably mounted on said sleeve partially closing the openings in said valve plate and a helical spring mounted on said sleeve arranged to elastically hold the follower plate against the valve plate, said sleeve being arranged to permit said valve 12, member to move from the throat in the valve bogy into the bellied portion of the valve bo 4. An air valve attachment for carbureters comprising. a cylindrical valve body sesame having a throat portion and a bellied. portion, support means formed on the outer end of said valve body, a rod rigidly mounted in said support, a sleeve slidably mounted en said rod, a valve plate secured to the inner end of said sleeve, and elastic means on the inner end of said rod arranged to elastically hold said sleeve against said support to hold the valve member on the sleeve in'the throat of the valve body.
In testimony whereof I have hereunto set my hand at Los Angeles, California, this 27th day of Mareh, 1918.
