Abstract

A rotary steam engine comprising a housing including at least first and second power units mounted therein. Each of power units include a pair of cylinders in communication with each other and having two rotors rotatably mounted therein. The rotors have peripheral gear teeth extending therefrom which are in mesh with the gear teeth of the other rotor. A rotary valve is centrally positioned in the housing with respect to the rotors and is adapted to successively supply steam to the power units to cause the rotation of the rotors therein. Each of the rotors have a drive shaft connected thereto which extend outwardly of the housing. A gear is mounted on the outer ends of each of the drive shafts. The gears on the drive shafts of the first power unit are in mesh with each other with the gears on the rotors of the second power unit also being in mesh with each other. The rotary valve has a drive shaft connected thereto which extends outwardly from the housing with a drive gear being secured to the outer end of the drive shaft. The drive gear is in operative engagement with one of the gears of the first power unit and in operative engagement with a gear of the second power unit. Rotation of the rotors causes the rotary valve to be rotated so as to admit and cut off the steam supply to the rotors at the proper times. The rotary valve is provided with a steam discharge opening which has an increasing opening area from one end thereof to the other end thereof to permit the rotary valve to be longitudinally moved with respect to oppositely disposed steam passageways to permit the amount of steam passing therethrough to be varied.
