Definitions
- This invention relates to an improved valve means for internal combustion engines.
- This invention is of a shaft-type valve wherein there are diametrical passageways arranged in the shaft
- the shaft of the instant invention has both longitudinal and circular seals to prevent gas from escaping.
- the components are of a structure which permits them to be very strong and there is a reduction in the number of working parts by reason of the utilization of the instant inven- tion.
- the system is adaptable for virtually all four cycle piston engines and is adapted to work well with fuel injection and stratified charge heads. It is also useful for diesel fuel where very high compres ⁇ sion ratios are required.
- the shafts and seal of the instant invention replace a large number of parts, estimated to be in the range of about 80, which are normally utilized to accomplish the same effect in a normal V8 engine reducing the expense of such engines.
- the engine is capable of turning at increased rpm's with a resultant higher horse power from the same displacement. Also, when used with the stratified charge type engine, the rich charge chamber can be shaped more efficiently than with normal engines which yields a greater degree of horse power for less polluting gases since the same are combusted more thoroughly.
- Figure 1 is a side elevation view in cross section of an internal combustion engine of the four cycle type
- Figure 2 is a partial view taken on the plane indicated by the line 2-2 of Figure 1 and' looking in the direction of the arrows;
- Figure 3 is a plan view in cross section of the upper zone of Figure 1.
- an inter ⁇ nal combustion engine generally designated by the numeral 12. It is composed of a block 14 having a 0 lower end spanned by an oil pan 16 in open communi ⁇ cation with the lower end of cylinders, such as that designated by the numeral 20 with the oil pan being secured to the block by suitable means, such as the bolt 21.
- the upper end of the block is provided with 5 a head 18.
- pistons 22 are recipro ⁇ cal in the cylinder 20, for example, being connected by a rod, such as that designated by the numeral 24 to a crank shaft 28 as at 26, and, specifically, to an eccentric portion thereof.
- the end 30 of the Q crank shaft is connected by a suitable means to a power takeoff and, at the other end, 32, a gear or other drive means is provided for engaging a belt, chain, or other type of force transmission means to the gear 38 on the end of a shaft 36 supported in 5 spanning relation of the side of the upper end zone of the cylinders and being supported such as by bearings 42 and 44 captivated between the upper portion 40 of the head 18 and the block.
- the shaft 36 is rotatable within a 0 tunnel through the head, generally designated by the numeral 41 and wherein there is an opening on the opposite sides in diametrical relation as at 43 and 53.
- the head is provided with a pair of t - coplanar surfaces 70 and 71 which abut the upper surface 73 of the block and are suitably secured thereto as by the bolts 75 and 77.
- the upper portion 40 of the head which spans the piston cylinders is elevated, as at 46 in the central longitudinally extending zone and curves downwardly and outwardly to the portions 70 and 71 on the block 73 as designated by the numerals 45 and 45' and through which the opening 43 is located in the case of the shaft 36.
- a shaft 37 is rotatable therein in a manner similar to that referred to above in connection with the shaft 36.
- Each of the shafts has a through bore as at 90 and 92 which is diamet ⁇ rical and extends completely across it and is of a diameter which is substantially one-sixteenth of the circumference of the shaft, one of which will be referred to as the intake shaft and one of which will be referred to as the output shaft.
- a bore 101 is provided for a spark plug 50 which will be utilized to ignite a fuel mixture which will be introduced and exhausted into the chamber 103 in a manner which will now be described.
- the intake shaft the one on the right in Figure 2, this will be referred to as the intake shaft and it serves as an intake valve.
- a fuel and air mixture is introduced into the hood 201 having the opening 203 leading into the tunnel so that when fuel and air are introduced through the opening 205, and the shaft is lined up with the opening 53, fuel will pass through and out the opening 43 and into the chamber 103.
- this passageway will be closed; and at that time a spark will be ignited as at 50 which will cause an explo ⁇ sion driving the piston 22 downwardly and, on its uptake stroke, the hole 92 in the shaft 37 will have rotated into alignment with the hole 302 in the hood 303 which is bolted as at 305 to the upper end of the head and the upwardly moving piston will cause the gases to exhaust through the opening 81 and diamet ⁇ rical passageway 92 through the shaft 37 to exit through the hole 301.
- the passageways 90 and 92 of the cylin ⁇ der 20 are elongated, that is, each has a substantial axially extending mouth to mate with the diametrical size of the cylinder.
- this opening in the shaft is one-sixteenth of the circumference of the shafts 36 and 37, which are equal in the preferred embodiment, i.e., the distance between the relatively long sides 403 and 405, and these are sized to cover approximately 80% of the diameter of the cylinder and piston and preferably at least as great as the radius of the cylinder.
- Seal means are pro ⁇ vided on each of the shafts. These seal means are of two types: As shown in Figure 2, circumferential slots which extend in the cord direction are pro- vided; and in each there is received a seal member 501 comprising a bar having an outer surface 503 in engagement with the inner surface of the head at all times in rotation and this provides a sweeping action against the inner surface of the head providing seal means to prevent blow by. Additional seal means are provided between each of the cylinders and between the bearings, as shown in Figure 1, 42 and the en ⁇ larged portion of the shaft 36, this seal means being designated by the numeral 601 and resisting any type of blow by axially. These seal means may resemble conventional piston rings and are seated in grooves located appropriately in the shafts.
- longitudinally extending passageways are provided in the groove for lubrication between the exterior surface of the shaft and the interior surface of the tunnel through the head, as indicated by the numeral 902, which are suitably fed as by oil lines 903, 904.
- This invention finds use in four cycle (Otto cycle) internal combustion engines.
- Suitable openings, shown through the shafts, and in the engine block are provided for water cooling of the same.
