(under subclass 508) Apparatus of a motor comprising a working member and a working chamber having liquid supplied thereto with means to vaporize the liquid concurrently with its introduction into the working chamber whereby the pressure produced actuates the working member.
(1) Note. Two or more fluids may be introduced into a preheated working chamber so long as at least one fluid is a liquid to be vaporized (e.g., air and water, water vaporized; oil and water, both vaporized).
SEE OR SEARCH THIS CLASS, SUBCLASS:
511, for motors wherein a second fluid is injected into a working chamber having a first fluid therein to result in a
change in pressure in said chamber.
512, for means within the working chamber to affect the pressure of the fluid therein.
SEE OR SEARCH CLASS 123, Internal-Combustion Engines, for motors in which a combustible material is burned with a chamber and the pressure produced thereby is converted into work, and
22, for internal combustion engines having working chamber into which air, per se, may be introduced and expanded to do work as a result of its contact with the hot walls of the chamber either as a step in the cycle of the internal combustion engine chamber or during a time when the chamber is converted to act as a hot air engine from internal combustion engine operation.
