Description: |
| Abstract:
In many types of internal combustion engines, especially those which are used in motorcycles, the compression is very high and difficulty is therefore experienced in starting such motors. Many operators attempt to avoid this difficulty by opening the exhaust valves and spinning the motor very fast until there is momentum enough in the flywheel to carry the motor over its high compression stroke, This operation however, is one which requires considerable skill and strength.
The object of our present invention is to avoid the difficulties outlined above by providing an internal combustion engine with an additional compression space which may be connected with or disconnected from the combustion chamber so that, when connected with the combustion chamber, the degree of compression while materially lessened, 3so nevertheless remains sufficient to make possible, without expenditure of great force, the ignition of the preliminary charges.
Claim:
As an article of manufacture, a compression-space annex for internal, combustion engines comprising a threaded stem having a valve seat formed at its lower end, a valve movably mounted in said stem and normally seated in said valve seat, at compression chamber carried by said stem and communicating with the bore thereof,a spring for normally holding said valve to its seat, and a cam arranged to operate said said valve to open the same. |
