v FUEL DISTRIBUTOR FOR INTERNAL COMBUSTION ENGINES Filed March 8, 1955 )NVENTOR. SAME: B. ueeAmc drraklvs' vs United States Patent FUEL DISTRIBUTOR FOR INTERNAL COMBUSTION ENGINES James E. Hoback, Kansas City, Mo. Application March s, 1955, Serial No. 493,019
2 Claims. c1. 137-62511) The present invention relates to fuel distributors of a rotary type for successively injecting liquid or gaseous fuel into the engine manifold adjacent to each of the intake valves.
The primary object of the present invention is to provide a fuel distributor for a multi-cylinder internal combustion engine having an intake manifold, and an intake valve for each of the cylinders, which valves are successively opened by a camshaft during the intake stroke of the piston within successive cylinders.
Another object of the present invention is to provide a distributing valve for liquid fuel which is operable upon rotation of a shaft connected to the camshaft of the engine.
A further object of the present invention is to provide a fuel distributor for an engine in which the fuel is injected into the intake manifold of the engine adjacent to each of the valves during the period when each of the valves is successively open.
A still further object of the present invention is to provide a fuel distributor for an internal combustion engine which is of simple and sturdy construction, economical to manufacture and install upon gasoline and diesel engines, and one which is foolproof in operation, requiring no adjustment other than the control of the pressure of the fuel being admitted to its intake port.
These and other objects and advantages of the present invention will be fully apparent from the following description, when taken in connection with the annexed drawing, in which:
Figure l is a vertical view in cross-section of the present invention showing its many elements, and showing a portion of an engine manifold,
Figure 2 is a vertical view on line 22 of Figure 1, and
Figure 3 is a view in perspective of the disk valve of the present invention as removed from the housing.
Referring in greater detail to the drawing in which like numerals indicate like parts throughout the several views, the invention consists of an upstanding housing having a hollow base 11 for support on the engine block indicated by the reference numeral 12.
Bolts 13 secure the housing cover 14 to the top end of the housing, over the circular chamber 15 in which is rotatable the disc valve 16.
The engine camshaft is indicated by the reference numeral 17 and has a gear 18 on it in mesh with a gear 19 at the end of a shaft 2!), the upper end of which is operatively connected to the valve 16.
A bushing 21 within the hollow base 11 is supported by a snap-ring 22. Packing 23 seals the shaft within the housing 10.
A portion of the engines manifold is indicated by the reference numeral 24, and shows a single valve 25, which represents the intake valve for a single cylinder of the engine.
The cover 14 is provided with a centrally disposed inlet port 26 in which is inserted the inlet nipple 27 having a 2,884,006 Patented Apr. 28, 1959 needlevalve 28 incorporated as part of its structure. A conduit 29 connects the inlet port 26 to a source of fuel under pressure. On the side of the housing opposite to the inlet port 26, a plurality of outlet ports indicated by the reference numeral 30 are provided with conduits 31 connecting each one of the outlet ports 30 to the manifold 24 adjacent one of the valves 25.
As seen in Figure 2, in dotted lines, the plurality of outlet ports total eight in number, although there may be more or less of them, depending upon the number of cylinders in the engine.
In Figure 3 is seen the disc valve 16, which is provided with a centrally disposed recess 32 on its upper face, the valve 16 possessing the cut away portion in the shape of a sector with the walls of the cut away portion, one of which is indicated by the reference numeral 33, arranged at an angle of relative to each other, as seen most clearly in Figure 2.
The periphery of the disc valve 16 is cut away at its lower end to provide a passage for the fuel from the inlet port 25 to each of the outlet ports 30, successively, while each of the associated valves 25 is in open position.
While here shown and illustrated as having a sector portion of 90, the disc valve 16 may be formed with a cut out portion of greater or lesser width, depending upon the fuel requirements of the particular engine for which it is to be used.
It is believed that optimum performance will be obtained when the fuel is injected into the manifold during all of the time that each particular valve 25 is open.
A suitable spray nozzle 34 may be used with the conduit 31 in order to atomize the fuel as it enters the manifold.
The portion of the disc valve 16 between the recess 32 and its lower peripherial edge is provided with a sloping face 35 within its cut out portion. This permits the even flow of fuel from the inlet port 26 on the top end of the housing 10 to the outlet ports 30 on the lower end of the housing opposite to the inlet port.
While a single embodiment of the present invention has been here illustrated and described, it is believed that other embodiments may be made and practiced within the scope of the appended claims without departing from the spirit of the invention.
What is claimed is:
1. In a fuel distributor, an upstanding housing having an inlet port disposed centrally in one wall thereof and having a plurality of outlet ports annularly disposed on a circle of one diameter in said housing in the wall opposite the said inlet port, and a rotary disc valve disposed in said housing between said inlet port and said outlet ports, said disc valve being proportioned to fit wholly within said housing between said inlet and outlet ports, having a diameter greater than said one diameter and being formed with a centrally disposed recess connecting with said inlet port and with a cut-away sector portion successively connecting in communication each of said outlet ports to said recess in the rotation of said valve, said valve having the walls of said sector portion extending vertically.
2. In a fuel distributor, an upstanding housing having an inlet port disposed centrally in one wall thereof and having a plurality of outlet ports annularly disposed on a circle of one diameter in said housing in the wall opposite said inlet port, and a rotary disc valve disposed in said housing between said inlet port and said outlet ports, said disc valve being proportioned to fit wholly within said housing between said inlet and outlet ports, having a diameter greater than said one diameter and being formed with a centrally disposed recess connecting with said inlet port and with a cut-away sector portion successively connecting in communication each of said outlet other.
