Abstract
Abstract A rotary piston machine which serves as the drive for fuel carburetor motors, or as a functional element for a motor, in a steam engine, as a compressor and pump. The machine is constructed in a hollow cylindrically-shaped housing and includes an axially hinged winged-shaped piston pivoted on a first axis and having at least two extending arms for sliding contact against the internal walls of the housing, a plurality of cylindrically-shaped rotary piston segments equal in number to the rotor arms and having perforated ends, and coupling joints slidably disposed on the extending wing-shaped piston arms. The sprockets are pivotably coupled within the perforated ends of the rim segments to the wing-shaped piston arms to close the segments around the hinged wing-shaped piston to form a second axis displaced parallel with respect to the first axis.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
144 words
An internal combustion rotary piston apparatus comprising; a hollow cylindrical housing; at least two rotary pistons, rotatably and eccentrically positioned within said housing so as to form compression and combustion chambers as said rotary pistons revolve with respect to said housing; a plurality of wing-shaped pistons forming a chassis on which each of said rotary pistons is secured; a shaft disposed concentrically with respect to said housing having one end fastened to said rotary pistons; and an overflow channel having an inlet and an outlet port positioned along the inside surface of said housing so that said channel connects the compression and combustion chambers in a manner so as to cooperate with said wing-shaped pistons so that the said inlet and outlet ports of said overflow channel are opened at the time when each of said compression and combustion chambers reach a certain volume.
Claim 2
Dependent Claim
144 words
An internal combustion rotary piston apparatus comprising; a hollow cylindrical housing; at least two rotary pistons, rotatably and eccentrically positioned within said housing so as to form compression and combustion chambers as said rotary pistons revolve with respect to said housing; a plurality of wing-shaped pistons forming a chassis on which each of said rotary pistons is secured; a shaft disposed concentrically with respect to said housing having one end fastened to said rotary pistons; and an overflow channel having an inlet and an outlet port positioned along the inside surface of said housing so that said channel connects the compression and combustion chambers in a manner so as to cooperate with said wing-shaped pistons so that the said inlet and outlet ports of said overflow channel are opened at the time when each of said compression and combustion chambers reach a certain volume.
Claim 3
Dependent Claim
65 words
An internal combustion rotary piston apparatus as recited in claim 1, wherein each of said rotary pistons comprise at least one notch on their outer surface and arranged in such a manner as to cooperated with said wing-shaped piston so that said inlet and outlet ports of said overflow channel are opened at a time when the compression and combustion chambers reach a certain volume.
Claim 4
Dependent Claim
85 words
An internal combustion rotary piston apparatus as recited in claim 1 comprising; a compression chamber internally and radially disposed inside each of said rotary pistons; a combustion chamber arranged outside and radially with respect to each of said rotary pistons; and a plurality of bevels disposed on the outside periphery of each of said pistons in order to open said inlet port in a rotary manner shortly before one of said wing-shaped pistons reaches said port at the radial internal edge of said rotary piston.
Claim 5
Dependent Claim
59 words
An internal combustion rotary piston apparatus as recited in claim 1 additionally comprising; a left and right housing, wherein said left housing is a compression chamber, and said right housing is a combustion chAmber; and a port connecting both housings in a manner so as to provide cooperation between the gas in said compression chamber and said combustion chamber.
Claim 6
Dependent Claim
45 words
An internal combustion rotary piston apparatus as recited in claim 1 comprising a plurality of groovelike indentations disposed at the outer radial edges of each of said pistons, so that said overflow channel acts as a connection between said combustion chamber and said compression chamber.
