` 12 claims. (ci izsifssy' This invention relates to new and useful improvements in valves. One objectof the invention is to provide an improved valve structure which may be readily install'edin the intake chamber of a gas engine 'to control' the admittance of fuel to said engine.

An important object of the' invention is to provide an improved valve structure including a valve head which is arranged to be mounted in the intake chamber of a gas engine in place of the usual large single valve; said head having a plurality of relatively light valves mounted therein, whereby battering or marring of the valve seat due to the pounding action rof a large valve, which is relatively heavy, against said seat is eliminated.

Another object of the invention is to provide an improved valve cluster which is adapted to be substituted for the usual single intake valve of a gas engine, wherein a plurality of relatively light Valves control the admission of fuel, said valves being actuated by the engine suction and due to their light weight are quick opening and closing, whereby fuel waste is minimized; each valve being individually mounted in the assembly to permit its repair or replacement without affecting the other valves.

A further object of the invention is to provide an improved valve cluster of the character described, wherein the stroke of the individual valves is limited which eliminates hammering or pounding of said valves in operation; said valves being arranged to seat on a head forming part of the assembly, whereby operation of the valves causes no appreciable wear on the engine valve chamber.

A construction designed to carry out the invention will be hereinafter described, together with other features of the invention.

The invention will be more readily understood fro-m a reading of the following specification and by reference to the accompanying drawing, in which an example of the invention is shown, and wherein:

Figure 1 is a transverse, vertical, sectional View of the intake chamber of a gas engine having a valve assembly constructed in accordance with the invention mounted therein,

Figure 2 is a plan view of the valve assembly,

Figure 3 is a transverse, vertical, sectional view takenon theV line 3 3v of Figure 2,

Figure 4 is an enlarged horizontal, cross-sectional view, taken on the line 4 4 of Figure 1, and

Figure 5 is a bottom View of the assembly.V

In the drawing, the numeral I0 designates the intake valve chamber of a gas engine which may be of any usual construction, such as may be purchased on the open market. The particular engine toy which the invention is 'applied` is subjectito vari-ation; as it has been found that the same is readily mounted in any of a number of standard-gasengines, namely, Bessemer, Superior, Marion, J. C., and Reid. The Avalve chamber is provided with a transverse partition YIl* located at sumtantially mid-height therein and `an. opening I2 in the top of the chamberijestablishes communication between the interior of the' chamber and the'corn'bustion chamber of' the engine (not shown). A horizon- 'tal inletport YI3rextends through the wall of the casing below thej partition II- to admit theV fuel mixture into the chamber lil, while a central cylil whereby the fuel Vmixture may flow upwardly :i

through said opening I Il and chamber, from 'where it is conducted to thev engine. Manifestly, by controlling the ow through the opening I4 inthe partition Il, thefuel' mixture admitted to the engine is controlled. Y

VThe upper vportion of 'the' opening I is enlarged' torform an annular seat I5and it has been the usual practice to employ a single valve Yadapted to engage the seat. Such a valve is guided' inits movement by a depending stem Whichis' s'lidable in a sleeve or collar I6 extending upwardly from the bottom of the chamber Ill.Y The'single Valve is comparatively heavy in weight and' since engine suction is depended upon to raise said valve, the operation of the same is relatively slow. Also, the'weight of the valve causes'the same to seat with a great deal of force'which batters the seat I5, resulting in a poor seating engagementwiththe valve. Vlhen said seat vdoes become worn, it is necessary to eitherV replace the entire intake chamber or remove the same from the lengine to repair it. Further, wear of the valve itself requires replacement of the entire valve.

To overcome theY disadvantages of a single valve such as is now in common use, a cylindrical valve head I1, is inserted within the opening I4 and is supported on the annular shoulder I5, as is clearly shown in Figure 1. An axial shank i8 depends from the head, being preferably made integral therewith, and said shank extends below the bottom of' the partition II .into the lower end of the chamber l0. An axial stem I9 has its upper end threaded in the bottom of the shank, while its lowerV end is inserted within the upwardly extending sleeve or collar I6. The bore of the sleeve is threaded to receive the lower threaded end of the stem and manifestly, the stem acts toisecurely fasten theV head Il' on the seat I5. y

Y A plurality of openings or ports 20 extend ver'- tically through the head', being preferably located an equal distance apart around the head. As is clearly shownin Figures'2 and 3f, the openings are disposed between the periphery of the head* and the shank I8, and establish communication between the upper and lower portions of the chamber I 0 on each side of the partition I I. The ports may vary in number according to the H. P. of the gas engine and although four have been illustrated in the drawing, the invention is not to be limited to any particular number.

For controlling the flow of fuel through the ports 2B, a plurality of valve members 2l are provided. Each valve member is arranged to closef one of the ports and since all of the members and ports are exactly alike, a description of one member and its engagement, with its respective port will sufce. Each valve member includes a valve disk 22 having an annular bevel 23 on its underside at its marginal portion. The upper end of each port is formed with a complementary bevel to form a seat 24 arranged to be engaged by the bevel of the valve disk. A valve stem 25, preferably integral with the disk, depends axially from the underside of said disk and passes through a vertical bore or opening 26 formed in a radially extending guide boss or collar 21. The guide collar is preferably made integral with the lower end of the shank I8 and as clearly shown in Figure 4, a guide collar is provided for each valve member and is so positioned that the stem 25 of said member passes through the bore thereof. A suitable .guide sleeve 28 is inserted in the bore 26 of each boss or collar and surrounds the stem. The sleeve has an annular flange 29 at its lower end which flange abuts the underside of the boss when in position within the bore. l

The lower end of each stem -25 extends below its boss or collar and is enlarged as shown at 30, whereby a flanged ring 3I may be slidably confined on the stem. A coiled spring 3 I surrounds each stem, being confined between the ring 3| and the underside of the boss or collar, and constantly exerts its pressure to urge the valve member downwardly with the disk 22 engaging the seat 24. Thus, said springs tend to hold the valve members in a closedposition, whereby communication between the lower end and the upper end of the chamber is prevented.

Manifestly, the valve members 2I control the now of the fuel mixture to the combustion chamber of the gas engine (not shown) and the size of the ports 2li is such that their combined area admits sufcient fuel when the disks 22 of the members are unseated. The suction of the engine acts upon the upper surface of the disks to unseat the same under tension vof the coiled springs 3|' and since the valve members are relatively light, said suction quickly opens the members. Similarly, when the suction is relieved, the springs 3I immediately seat the disks to close the openings. The lightness of the members obviates the pounding or hammering action against their seats which prolongs the life of both the seats and disks.

To limit the upward movement of the valve members 2I so that the suction does not raise said members farther than is necessary, a spider 32 is formed with a central depending collar 33, which collar rests on the top of the head I1 at the central portion thereof. The spider arms 34 overhang the disks 22 of the valve members 2I and a stud bolt 35 passes through a vertical axial bore 36 formed in the spider and collar and is threaded into the head I'I. Obviously, upward movement of the members is limited by the disks 22 striking the spider arms 34. It is noted that other means for limiting the upward movement of the members may be employed, such as providing a projection on the stem LS-arranged to strike the underside of the boss and therefore, the invention is not to be limited to any particular type of stop means.

From the above, it will be seen that a plurality of small, relatively light valves are mounted in a single assembly which is substituted for the usual single valve. The valves are positive in operation being quick opening and closing, which results in fuel saving and more efficient engine performance. Further, the valve disks and seats are not subject to severe pounding or hammering action because ofthe lightness in weight of the valves and also because of the limited movement which the valves undergo. If any one of the valve members become worn, it can easily be replaced Without aifecting the other valve members. Also, if the seats become worn the assembly may be removed and said seat re-ground, or an entire new assembly substituted therefor. It is particularly noted that the construction herein shown causes no wear on the intake chamber as the shoulder I 5 therein merely supports the head and does not act as a valve seat, as has been the practice heretofore.
