Description: |
| Abstract:
This invention relates to that class of engines which are driven by the energy of exploding gases and known as gas motors, and has for its object to simplify the construction thereof and to increase their efficiency by permitting the exploded charge to expand to the utmost before it is exhausted, and then cooling it within the cylinder without reducing its volume, its expansion, exhaust, and the intake of a fresh charge all being accomplished during a single revolution of the crank-shaft driven by the piston.
It consists in a novel construction and combination of the several parts of the machine, substantially as hereinafter described and claimed.
Claims:
l. A gas-engine having a single piston working in a single cylinder provided at its outer end with an exhaust-vent and at its inner end with a supply-port for the admission of an explosive charge, the middle of the' cylinder and its outer or exhaust end being connected by communicating passages governed by a valve moving in synchronism with the piston, whereby said communicating passages are closed as the piston, impelled by the explosion of the gaseous charge, makes its outstroke, and upon the return-stroke said passages are opened during the first portion and closed during the remainder of said stroke, thereby permitting during the out-stroke a full expansion of the exploded charge and during the in-stroke a displacement of the burned charge to the exhaust side and an in-draft and compression of a fresh charge at the compression side of the piston preparatory to an explosion at the end of said in-stroke, substantially in the manner and for the purpose herein set forth.
2. In a gas-engine, a single cylinder having passages establishing communication between the middle of its length and its outer end and recesses in its inner periphery connecting with said passages, a valve controlling said communication and the communication between the outer end of the cylinder and an exhaust-vent, and a piston working in said cylinder and actuating immediately said valve, substantially in the manner and for the purpose herein set forth.
3. In a gas-engine, a single cylinder having an explosion-chamber at its inner end and an exhaust-port at its outer end, a hollow extended piston moving in the cylinder, a displacing-block at the outer end of the cylinder, upon which the piston is carried at the end of its outstroke, passages establishing communication between the middle of the cylinder and its outer end, and a valve actuated immediately by the movement of the piston and controlling said passages, substantially in the manner and for the purpose herein set forth.
4. A gas-engine constructed, substantially as described, of a single cylinder having an explosion-chamber at its inner end, an exhaust-port at its outer end, and a passage establishing communication between the middle of its length and said outer end, and which is provided with a piston moving therein over the ports into said passages, an inlet valve for the charge, an igniting device connecting with they explosion-chamber, a crankshaft coupled to the piston, and valves actuated thereby to control the igniting device, the exhaust-port, and the communicating passage, all arranged and operating substantially as set forth, so that during one revolution of the shaft the exploding charge shall, after propelling the piston outwardly and thereby expelling the previously-exploded charge through the exhaust, be displaced from one side of the piston to the other upon its return-stroke, and thereby so expanded and cooled as to create an in-draft for afresh explosive charge, which shall be compressed into the explosion-chamber by the completion of said return-stroke.
