Abstract:
An internal combustion engine of the rotary-reciprocal type comprising, a housing formed with peripheral wall with side walls which contains a cylindrical inner wall attached to one of said side wall at 90 degree, inner surface of said peripheral wall being cylindrical, a peripheral circular piston having anterior peripheral located equally spaced wave shaped anterior side wall with the first portion of the wave from the crest of the wave to the trough of the wave being longer than the second portion of the wave from the trough of the wave to the crest of the next wave, rotatably and reciprocal mounted in said housing, a rotor, having means for the said piston to reciprocate on and rotate with said rotor, said rotor is attached to a shaft, said shaft extending through said side walls and rotates with said rotor, said housing having a lateral and peripheral circular cylinder chamber having equally spaced arcuate recesses with the inner surface of the said arcuate recesses from the minimum recessed area to the maximum recessed area is a longer distance than the distance from the maximum recessed area to the minimum recessed area of said arcuate recesses, said arcuate recesses extending into said cylinder chamber's side wall, the number and shape of recesses being equal to the number and shape of the waves on the piston's anterior side wall and the number being 2 or more, piston's waves movably mounted in each of said arcuate recesses respectively, the piston's peripheral and inner circular surface remaining in sealing contact with the inner peripheral wall, the peripheral surface of the circular inner wall at all times and any seal on the crest of the wave of the piston remaining in sealing contact with the inner wall's peripheral surface, peripheral housing wall's inner surface and arcuate recesses of said side wall and forming variable volume cylinder chambers between the piston's waved side wall and said cylinder chamber walls, said housing being provided with means for admitting a gaseous mixture communicating with said cylinder chambers, means to discharge combustion products communicating with said cylinder chamber, ignition means communicating with said cylinder chamber, means to guide piston's rotary and reciprocal motions in said housing, said cylinder chamber of varying size enabling compression of a gaseous mixture to take place after suction, ignition of said compressed gaseous mixture and expansion of said chambers due to the pressure of said combustion products.
