Description: |
| Abstract:
Our invention relates to internal combustion engines and has for its object to provide a two-cylinder, two-cycle engine controlled by novel valve mechanism, a single such mechanism being operative to control both engine units.
Claim:
A two-cycle engine comprising a cylinder casing having a series of annular exhaust ports and a series of annular inlet ports spaced therefrom, a casing surrounding said cylinder and providing separated annular passageways in communication with said exhaust. ports and said inlet ports, respectively, a valve chamber connected with said annular passageways, means for admitting fuel mixture into said valve chamber and for permitting escape of exhaust gases therefrom, and a single valve movable in said chamber for controlling said fuel and exhaust gases. A two-cycle engine comprising a cylinder casing having a series of annular exhaust ports and a series of annular inlet ports spaced therefrom, a casing surrounding said cylinder and providing separated annular passageways in communication with said exhaust ports and said inlet ports, respectively, a valve chamber connected with said annular passageways, means for admitting fuel mixture into said valve chamber and for permitting escape of exhaust gases therefrom, and a single valve movable in said chamber for controlling said fuel and exhaust gases, said valve comprising a diaphragm separating the fuel admission and exhaust portions of the valve camber. |
