Vacuum engine

An engine comprising:

• at least one variable volume chamber;
• a controlled intake passageway communicating with said chamber, said intake passageway being controlled to open during expansion of said variable volume chamber;
• a controlled exhaust passageway communicating with said chamber, said exhaust passageway being controlled to be open when said chamber is near the minimum volume thereof;
• means for dispersing water in said chamber, said dispersing means being controlled to operate when said chamber is near the maximum volume thereof, said controlled intake passageway and said controlled exhaust passageway being closed during the contraction of said variable volume chamber;
• and
• means for providing ammonia gas to said intake passageway.

An engine comprising:

• at least one variable volume chamber;
• a controlled intake passageway communicating with said chamber, said intake passageway being controlled to be open during expansion of said variable volume chamber and to be closed during contraction of said variable volume chamber;
• a controlled exhaust passageway communicating with said chamber, said exhaust passageway being controlled to be open during contraction of said variable volume chamber;
• a solution tank, said solution tank being sealed and in communication with said exhaust passageway for the passage of gas therebetween;
• said solution tank containing only water and the exhausted gases from said chamber said solution tank including means for physically dispersing exhausted gases below the level of said water;
• and
• means for providing ammonia gas to said intake passageway.

A method of generating mechanical power in a variable volume engine including the steps of:

• filling a variable volume chamber with a gas;
• dispersing a liquid solvent for the gas into the chamber when the volume thereof is near a maximum;
• allowing the soluble gas to dissolve in the solvent liquid;
• deriving power from the resulting decrease in pressure experienced within the chamber;
• exhausting the solvent and dissolved gas from the volume;
• and
• repeating the above said steps.

A method of generating mechanical power in a variable volume engine, including the steps of:

• supplying a variable volume chamber through a passageway with a gas;
• closing the passageway to cut off the supply of gas to the variable volume chamber;
• establishing an initial vacuum in a remote solution tank;
• placing the variable volume chamber in communication with the remote solution tank;
• dispersing the gas in a solvent for the gas in said remote solution tank;
• deriving power from the resulting decrease in pressure experienced within the chamber;
• and
• repeating the above steps.

An engine comprising:

• an intake passageway;
• an exhaust passageway;
• means located between said intake passageway and said exhaust passageway for deriving power from a gas pressure differential between said intake passageway and said exhaust passageway;
• means for providing a gas to said intake passageway;
• a solution tank, said solution tank being sealed and in communication with said exhaust passageway, said solution tank containing a solvent for the gas and an initial vacuum above said solvent said exhaust passageway extending into said solvent for dispersing gas passing through said exhaust passageway with said solvent for the gas.
