Application January 14, 1943, Serial No. 472,382
This invention ,relates to a control device for valves of internal combustionengines of the type shown and described in my pending application, Serial No. 457,861, filed September 10, 1942, now Patent Number 2,352,682, granted July 4, 1944, the primary object of the invention being to provide means for feeding the oil fuel to the engine. in such a way that the amount of oil entering the engine may be accurately regulatedfor the eflicient operation of the engine.
Another important object of the invention is to provide a needle valve control means designed for manually shutting the valve to regulate the movement of the valve, and consequently regulate the quantity of fuel oil entering the engine, to insure the thorough mixing of the fuel oil and air to provide perfect combustionunder varying conditions of use.
Still another object of the invention is to provide exceptionally simple means for accomplishing adjustment of the valve, eleminating complicated valvecontrol mechanisms, which are frequently rendered inoperative.
With the foregoingand other objects in view which will appear as the description proceeds, the invention consists of certain noveldetails of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.
Referring to the drawings,
Figure 1 is an elevational view illustrating engine cylinders, equipped with the improved structure, forming the subject matter of the present invention.
Figure 2 is a plan view thereof.
Figure 3 is an end elevational view of the device.
Figure 4 is a sectional view taken on line 4-4 of Figure 2.
Figure 5 is a sectional view taken on line 55 of Figure 3.
Referring to the drawing in detail, the reference character 5 designates the engine cylinders of a four-cylinder engine. Each cylinder head is provided with a fuel inlet port 6 which communicates with the charge-forming device of the engine, through the valve chamber 1, and passageway 8, the valve chamber I being provided with a valve seat at its base, to be engaged by the needle valve 9 which has one end thereof, extended into the passageway 8.
A flange indicated at 0 is formed on the needle valve, and provides a stop for the lower end of 2Claims. (01.137-144) I 2 the coiled spring H which has its upper end engaging the threaded member |2, whereby'the tension of the spring may be regulated. The member I2 is fitted in threads formed on the wall of the valve chamber 1. I
An adjusting nut I3 is provided on the threaded extremity of the needle valve 9, and provides a stop against which the rocker arm l4 engages; elevating the needle valve to admit a quantity of oil to the passageway 8.
Therocker arm I, is pivotally mounted on the shaft l5 which in turn is supported by the'bracket l6 associated therewith, which bracket is mounted on the cylinder head. As shown, the rocker arms H of a multi-cylinder engine, are pivotally supported at a point nearer to one endthan the other, leaving a substantially long portion of the rocker arm at one side of the shafts l5.
The reference character I! designates push rods which extend through openings in one end of the respective ends of the rocker arms associated therewith, there being provided a coiled spring I8 mounted on each push rod, the spring having its upper end bearing against the push rod, while the lower end thereof rests on the adjustable collar l9 secured to the push rod. A nut indicated at 20 is mounted on the threaded upper end of each push rod and is adapted to engage its rocker arm, adjusting the tension of the spring l8.
The regulating device, forming the essence of the present invention, includes a shaft 2| that extends over the cylinder block of the engine, the ends thereof being mounted in brackets 22 that are supported at the ends of the cylinder blocks. Secured to the shaft 2|, are cams 23 that are disposed directly under the rocker arms of the engine, the cams operating to elevate the rocker arms, and consequently raise the needle valves with which the rocker arms are connected, adjusting the initial positions of the needle valves.
The bracket 22 at one end of the cylinder block, is substantially wide and is provided with an arouate shaped slot 24 disposed adjacent to the curved upper edge thereof, the slot 24 being designed to accommodate the bolt 25 on which the indicator 26 is mounted. The indicator 26 is also keyed to the shaft 2| to move therewith.
A coiled spring indicated at 21 is mounted on the bolt 25 and bears against the indicator 28, holding the indicator into close engagement with the bracket 22 associated therewith. The outer end of the spring 21 engages the head 28 when secured to theouter end of the bolt 25, the head providing a finger piece, whereby the bolt 25. together with the indicator 26, may be swung 3 throughout the length of the slot 24 to adjust the shaft 2i, and consequently adjust the positions of the cams 28 mounted thereon. Graduations are formed along the upper curved edge of the wide bracket 22, which graduations cooperate with the indicator in determining the degree of movement of the shaft 2|.
from the foregoing it will be seen that due to the construction shown and described, the at-.
tendant or operator of the ensine, may. by mtating the shaft :I, move the various cam throughout the length of the cylinder block simultaneously, thereby insuring an accurateadjustment of all of the needle valves controlling the flow of fuel oil, to the charge-forming devices of the various cylinders.
In the operation of the engine, the-push rods I! move downwardly, rocking the arms II to elevate the needle valves connected therewith. when the cams have been adjusted to vary the initial flow of oil to the cylinders, it will be seen that the distance of opening of the needle valves may be regulated.
with the structure shown by applicant, the valves may be adjusted so that they will be maintained open a predetermined distance, at all times, or may be moved so that the initial positions of the needle valves, will close the valve chambers to exclude the passage of oil into the charge-forming devices.
What is claimed is:
1. A control device for valves internal combustion engines, comprising a plurality of .leedle valves, a pivoted rocker arm operatively connected with each needle valve, rocker arm adjusting means embodying a horizontal shaft disposed under the rocker arms, cams secured to the shaft, each cam contacting with the lower surface of its respective rocker arm, said cams restricting movement of the rocker arms. and said shaft and eamsadaptedtoberotatedtherebytosimulta- 'neouslyadjusttheoperatingpoaitionsoitheneedlevalvesregulatingthepalage offuelthrough 2. 11 fuel control means for valves of internal combustion engines. computing a plurality of needle valves. a pivoted rocher arm operatively connectedwitheachofsaidneedlevalves,asupportforeaehrockermrockerarmadjmting means embodying a horiaontal shaft, cams seucuredtosaidshafaeaohofaaidcamsbeing mountedunderitsrespeetiveroekerannincontact therewith at a point between the support andvalve. saidcamsrestrictingthethrowofsaid rocker arms thereby to simultaneously adjust the positionsoftheneedlevalveswhentheshaftis rotated. r s ating the passage of fuel through the valves.
