Specification of Letters Patent.
Application filed September 7.1906. Serial No. 833.665.
To all whom, it may concern:
Be it known that I, FREDERICK LAnPLoUor-I, a subject of the King of Great Britain, residing at London, England, have invented new and useful Improvements in Internal-Combustion Engines, of which the following-is aspecification. I
The invention relates to that type of internal combustion engine idwhich the carbnreting liquid isinjected into the cylinders by a pump.
The objectoi the present invention is to construct improved means whereby the action of the pump may be regulated so that more or less carbureting liquid may be injected into the cylinder, according to requirements and to provide a diaphragm controlled needle' valve to the petrol nozzle.
The invention is illustrated in the accompanying drawings in which:
Figure 1 is a sectional elevation of an improved internal combustion engine with the invention applied thereto. Fig. 2 is an elevation of the engine drawn. at right angles to Fig. 1. Fig. 3 is an enlarged sectional elevation of the; upper parts of Fig. 1. Figs. 4 to 11 are detail viewsoi various parts of the regulating In all the figures like letters and numerals oi reference indicate the same parts. i V
a is the smaller cylinder, b the larger cylinder, 0 the prolongation connecting the two pistons. f is the connecting rod which at one end is pin jointed at 9 while the other end passes out through the open end of the cylinder b and is connected to'the crank it on the shaft p, i is a water jacket surrounding the smaller or firing cylinder a. I
In conjunction with this engine is employed a small surface condenser j for the purpose of cooling the ex haustgases and assisting in the formation of a vacuum and in conjunction with this condenser a silencer k is employed, p v
The condenser j with its water chamber 1 tubes m,
together With the spherical silencer chamber 7:: periorated dome '2 therein, and the external radiating gills tand conducting chamber u connecting with the exhaust pipe 12 do not form an essential part of the particular improvement herein claimed-as new.
The larger cylinder b has a port y which opens into 1. communicating with the atmosphere and an inlet valve 2 communicating with a pipe 3 leading from the outer casingj of the condenser. The firing champartial vacuum in the firingchamber 5 and this latter is also provided with a-nozzle 7 through which petrol is pumped by the apparatus hereinafter described. A valve 8 regulates the amount oi depression in the cir-- cuit between the exhaust port 10 and theinlet' valve Patented July 9, 1907,; V
The petrol nozzle 7 is provided with a cheek needlevalve 9 controllcdby a diaphragm 10. 1 1 1 The suction chamber 11 of the petrol pump communicates with the petrol tank whiclrlattcr is under slight pressure and such chamber 11 is provided with a non-return valve 12; its plunger 13 is pressed downwards by a spring 14 and is forced upwards by an are or quadrant 15 operated by a rod 16 pivoted at one end to the connecting rod f of the engine and at the other end to an L shaped lever 1.7, thcshorter arm of which 'latter is pivoted to one end of the quadrant 15. The quadrant 15 is pivoted at its other end to one end of a link 18 the other end of which is pivoted. to a bellcrank lever 15) mounted on a shaft 20 and having a toothed segment 21 formed thereon. A sliding rod 22 has inc: ned or skew gear teeth which gear with the toothed egment 21 the teeth of which are correspondingly formed. This sliding rod 22 is operated by connectionrv capable of being operated by the driver from his seat By these means the quadrant 15 is caused to rise or iallat one end according to requirements and thereby gives a larger or smaller delivery of petrol by altering the stroke of the pump. i v I j The needle valve 9 of the spray nozzle? is caused to open. by the pressure of petrol when forced through by the, pump, and it immediately closes by the action of the diaphragm 10 when the pump plunger 13 has reached the end of its stroke.
The valve 8 is caused to. synchronize in its motion with the movement of the sliding-rod 22 so that according to the amount of opening of valve 8 so must the motion of the sliding-rod be.varied. The varying degrees of vacuum will. cause the cylinder (1 to fill with more or less air consequently a proportionately smaller or larger charge of petrol must be injected. According to the strength of the explosion, so is the quantity of petrol admitted to the ekplo sion chamber. As this mixture is very rich round the point of firing, it is easily fired, althou h close to the piston c there may be simply a layer of arr. The speed of the engine is thereby controlled. r
The action of the engine is as iollows:--On the firing stroke the larger piston d creates a partial vacuum in the condenser casing j and as soon as the smaller piston c has passed the exhaust port to the partial vacuum sucks out the products of combustion-and creates a partial vacuum in the firing chamber 5 sucking in fresh air through the inlet valve 6 On the return stroke the larger 'piston d ejects the gases through the exhaust valve 1 and the smaller piston c compresses 'the fresh air in the firing chamber 5. During the return stroke a certain amount of petrol has been pumped into the firing chamber 5 and is fired in the ordinary \wa y a two cycle engine although it accomplishes the equivalent ma suctionstroke, compression stroke, firing stroke and exhaust per revolution in perfect rhythm" Without the aid of timing gear.
What I claim is:- I
1. In an internal combustion engine, the combination of a pump having a suction chamber communicating with the petrol tank, a non-return valve in said suction chamber-,a pump-plunger,pressed downwards by a spring and forced upwards by aquadrant, an L shaped lever pivotally connected byits shorter arm to one end of the quadrant, and by its longer arm to the engine connecting rod, to move the quadrant to and fro under the petrol pumpplunger, a lever mounted on a shaft and having a skew toothed segment formed thereon, a link connecting said lever with one end of the quadrant, and a sliding. rod having skew teeth thereon gearing with the toothed segment.
:2. In an internnl'combnstion engine, the combination presence-of two witnesses.
of a purnp having a suction chamber communicating with the petrol tank, a non-return valve in said suction chem her, a diaphragm-controlled needle valve to the petrol nozzle, a pump-plunger pressed downwards by a spring' said lever with one end of the quadrant, and a slidingrod having skew teeth thereon gearing with the toothed qseg ment. p
In witness whereof I have hereunto set-my hand in FREDERICK LAMPL'OUGH. I Witnessesz-m i WM. Gimme,
