Rotary reciprocal combustion engines

A rotary-reciprocal combustion engine having a cycle of two strokes, compression and expansion wherein exhaust and intake takes place at the end of the expansion stroke;

• said engine comprising;
• a) housing formed with a peripheral wall with side walls, a rotor in said housing, the inner surface of said peripheral inner wall being cylindrical, said housing having laterally and peripherally spaced cylinder chambers formed with walls consisting of the inner cylindrical surface of the peripheral housing wall, a peripheral area of one side wall and an inner circular wall attached to said side wall of the housing and extending parallel with the peripheral wall of the housing toward the center of the housing thereby leaving space in the housing for the rotor to rotate and reciprocate, said one side wall having equally spaced arcuate recesses projecting into the cylinder chambers, said housing having an anterior central compression chamber and a posterior compression chamber separated by the rotor and being provided with means for admitting a gaseous mixture communicating with said cylinder chambers, means for discharging combustion products communicating with said cylinder chambers, said posterior and anterior central compression chambers having means for admitting and discharging a gaseous mixture:
• b) said rotor formed with a thick peripheral wall with one side wall at 90.degree. to peripheral wall, said peripheral wall is cylinderical, said thick peripheral wall is the rotor's piston having equally spaced waves on the said side wall of the rotor's piston, said waves being of equal number and shape of said arcuate recesses, wherein the number of the waves and arcuate recesses is greater than two, the rotor's piston having means to divide the housing's cylinder chamber into two or more sealed cylinder chambers, said rotor's side wall having a centrally located hub which extends at 90.degree. to the rotor's side wall and the hub has an opening in the center of the hub for an engine shaft, the rotor is rotatably and reciprocally mounted in said housing with the rotor's piston waves movably mounted in each of said arcuate recesses respectively remaining in sealing contact with said cylinder chamber walls;
• c) a shaft mounted in the center of the housing, passing through the rotor's hub and extending through the side walls of the housing, said hub having means to allow the rotor to reciprocate on the shaft while the shaft is rotating with the rotor;
• d) a reciprocal and rotary guide having means to guide the rotor's rotary and reciprocal motions of the rotor while keeping the rotor's piston in continuous sealing contact with said cylinder chamber walls and varying the volume of the cylinder chambers enabling a compression of a gaseous mixture to take place after aspirating a gaseous mixture;
• e) an ignition system having means for igniting compressed gaseous mixture and expansion of said cylinder chambers due to pressure of said combustion products.

A double rotary-reciprocal combustion engine having a cycle of two strokes, compression and expansion wherein exhaust and intake takes place at the end of the expansion stroke;

• said engine comprising:
• a) a housing formed with a peripheral wall with side walls, a rotor in said housing, the inner surface of said peripheral wall being cylindrical, said housing having bilaterally and peripherally spaced cylinder chambers wherein each are formed with walls consisting of the inner circular surface of the peripheral housing wall, a peripheral area of one side wall and one of the bilateral inner circular walls each attached to different side walls of the housing and both extending parallel with the peripheral wall toward the center of the housing thereby leaving space in the middle of the housing for the rotor to rotate and reciprocate, both said side walls having equally spaced arcuate recesses projecting into the cylinder chamber with the maximum recessed area of the arcuate recesses on one side wall of the housing being directly opposite to the maximum recessed area of the arcuate recesses on the other side wall of the housing, being provided with two anterior central chambers which are separated by the rotor, being provided with means for admitting a gaseous mixture into the anterior compression chambers, means for communicating each anterior central compression chamber with the opposite cylinder chambers, means for discharging combustion products communicating with each cylinder chamber;
• b) rotor formed with thick peripheral walls and one center wall at 90.degree. to the housing peripheral wall, said thick peripheral wall is cylindrical, said thick peripheral walls are the rotor's pistons, one on each side of the center wall, the rotor's pistons having equally spaced waves on each side wall at 90.degree. to the peripheral wall, said waves being of equal number and shape as said arcuate recesses, having the crest of the wave on one piston being directly opposites to the trough of the wave on the other piston, said rotor's center wall having a centrally located hub which extends at 90.degree. bilaterally from the center wall and the hub has an opening for an engine shaft, the rotor's pistons having means to divide the housing's cylinder chambers into two or more sealed cylinder chambers on each side, the rotor is rotatably and reciprocally mounted in said housing with one of the rotor's piston's waves movably mounted in each of said arcuate recesses respectively remaining in sealing contact with said cylinder chamber walls on one side of the rotor and on the other side of the rotor the crest of the piston's waves are directly opposite to the most recessed area of the other arcuate recesses respectively remaining in sealing contact with said cylinder chamber walls;
• c) a shaft, mounted in the center of the housing, passing through the rotor's hub and extending through the side walls of the housing, having means to allow the rotor to reciprocate on the shaft while the shaft is rotating with the rotor;
• d) a reciprocal and rotary guide having means to guide the rotary and reciprocal motions while keeping the rotor's pistons in continuous sealing contact with said cylinder chambers walls and varying the volume of the cylinder chambers enabling a compression of a gaseous mixtures to take place after aspirating a gaseous mixture and expansion of combustion products;
• e) an ignition system having means for igniting compressed gaseous mixture and expansion of said cylinder chambers due to pressure of said combustion products.
