INTERNAL-COMBUSTION ENGINE.
Application tiled November 21, 1927. Serial No. 234,741.
This invention aims to provide a simple engine of the internal combustion type whlch will operate effectively without valves, there being few parts in the engine, and there being little likelihood that it will get out of order.
It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.
With the above and other objects in view which will appear as` the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of theinvention.
Figure 1 shows in longitudinal section, a device constructed in accordance with the invention, the piston being at the end of the power stroke;
Figure 2 is a similar View, wherein the piston is shown at the end of the compression stroke;
Figure 3 is a fragmental transverse section on the line 3-3 of Figure 1;
Figure 4 is a section on the line 4-4 of Figure 2.
The device forming the subject matter of this application includes a crank case 1 connectedvat 2 to any desired number of cylinders 3. A fuel chamber' 4 is located in spaced relation to the cylinder heads but is joined thereto by reduced tubular Guides 24 which serve, also, as a means where the fuel finds its way from the fuel cham er 4 into the cylinders 3. The cylinder heads are secured in place in the usual way, as indicated at 5. The guide 24 has a short extension 34 which projects into the cylinder 3, there being ports 44 in the extension 34, the ports communicating with the combustion space of the cylinder 3. s
A conduit 9 o ens into the fuel chamber 4 and is connecte with any suitable means 10 whereby a charge of fuel under pressure may be forced into the fuel chamber through the conduit 9. The cylinders 3 are provided near to their butt ends with exhaust ports 11 that communicate with an exhaust manifold 12.
`In each cylinder 3, a piston 14 is mounted for reciprocation. The piston 14 has a reduced stem 15 of such diameter as to tit closely but .slidably in the guide 24. The piston 14 carrles a wrist pin 17 connected to a pitman 18 pivoted on a crank 19 located in an engine shaft 20 which is journaled in the crank case 1. The charge in each of the cylinders 3 is fired by any suitable means, for instance, by a lpak plug 21 located near to the cylinder When the piston 14 is in the position shown 1n Fi ure 2, the stem 15 closes the ports 44, and t e charge is under extreme compression. At this time, the charge is fired by means of the plug 21 or any equivalent mechanism, and the piston 14 performs its power stroke, the piston being shown at the limit of its power stroke travel in` Figure 1. When the parts are arranged relatively to each other as shown in Figure 1, the stem 15 has cleared the ports 44, and the piston 14 has cleared the exhaust port 11. The fresh charge can now move into the cylinder 3 from the fuel chamber 4, by way of the guide 24 which has now become a passage for the fuel, the fuel iiowing through the ports 44 into the cylinder 3. The incoming charge aids in scouring out the exhaust through the port 11 into the manifold 12. Owing to the fact that the extension 34 is rovided, the piston stem 15 never is quite wit drawn, and the stem, therefore, may carry packing rings 6, if desired.
The device is very simple in construction and calls for no valves, the stem 15 on the piston 14 takin the place of a valve.. The engine is so ma e that it will withstand hard and long continued use and still remain opery ative.
What is claimed is A11 internal combustion engine comprisiner a cylinder having an exhaust port in its side, a transversely enlarged fuel chamber, a guide of less diameter than the chamber, and of less diameterthan the cylinder, the guide formin a connection between the chamber and t e cylinder and having an extension which projects into the cylinder, the extension being supplied with an inlet port communicating with the cylinder, a piston slidable in the cylinder and constituting means for opening andlosing the exhaust port, the piston having a reduced solid stem slidable in the guide and in the extension to bearing in the extension when the piston is such a position that the extreme end surat the limit of its stroke to open the exhaust face of the stem will clear the intake port and port. 10 establish `communication between the cham- In testimony Ythat Iclaim the foregoing as 5 befand the `cylinder by Way of the inlet `port my own, I have hereto affixed my signature.
