BACKGROUND OF THE INVENTION
The related art outlined below discloses an apparatus for generating rotational powers to vehicles. However, the prior art fails to disclose the presently described rotary engine in which a Rotor rotates in a spherical or cylindrical housing in which the center of rotation of the Rotor is at a precise center of sphere or cylinder with minimal tolerances in deviation of the center of rotation of a shaft and the Rotor preventing frictions and wear and tear of the point of contact of the Rotor with the internal wall of the housing. This simple scheme of generating a compression chamber inside a spherical or cylindrical shape housing give rise to an efficient engine with minimum number of moving parts. In most cases, the existing art for a rotary combustion engine, essentially teaches us of a piston and cylinder in which a piston makes linear reciprocating motions inside a cylinder to deliver rotational power. The present disclosure distinguishes over the prior art providing heretofore unknown advantages as described in the following summary.

ADVANTAGES OF THE INVENTION
The invention differs from most of the previous art internal combustion engine in which the combustion chambers expand radially Unlike the present art, this invention provides expansion of combustion chamber between a blade like Rotor that is directly attached to the shaft and extended outward towards the inner surface of the housing of a cavity, and radially rotating inside the cavity. A combustion chamber is formed between a Rotor attached to a shaft and a blade like Blocker, making temporary transitional motions to form a barrier inside the cavity and form a combustion chamber. The combustion chamber is formed between the Blocker and the Rotor during combustion time, the Blocker remains stable and the Rotor rotates radially forcing the shaft to move with it.
This is a radical difference between the original Wankel rotary engine. The Wankel's rotation of the Rotor is in an elliptical housing and the center of rotation consists of a set of gears to guide the motion in a elliptical cavity. In the most recent patents of so called rotary engines, a reciprocating piston and cylinder configurations is used for combustion chamber and expansion of ignited gas.
The Wankel engine housing for the generation of pressured air and combustion of pressured air and gas is elliptical. Elliptical housing for the rotor is one of the sources of problems including the frictions between the housing and the rotor.
In order for the elliptical motions to take place, the shaft is connected to series of gears for the elliptical rotations. Generation of elliptical rotation through gear system is the cause and a major contributor of friction. By comparison:

    
    
        This invention resorts to a circular housing in which the shaft rotates in a center of the circular housing eliminating the requirements of elliptical motions and the necessity of gear system.
        The Rotor is a blade rotating in a spherical or cylindrical housing along the centerline of the housing resulting in minimal deviation in tolerances of the point of contact between the edge of the Rotor and the housing.
        Minimal tolerance variations avoids severe loading (pressure) between the edges of the Rotor and the internal walls of the housing, preventing frictions and wear and tear.
        The centrifugal force of the rotor in Wankle engine, the variation of tolerances acts as a hammering force destroying the tip of the rotor and the housing.
        The Blade shape Rotor and the Blocker provides for greater combustion chambers volumes within the cavity compared to Wankel engine's triangular shape rotor (for the same size volume of an engine). This increase in volume of the combustion, results in greater torque and rotational output power.
        Far smaller number of moving parts allows the engine to be built economically with advantage of greater efficiency in terms of conversion of gas to heat.
        Far lower frictions for eventual higher miles per gallon of gas.
        Far lower maintenance cost.
        Different option implementation for the type of engine allows:
        The design allows for the air compression to be implemented within the same cavity or external air suction and pump to be implemented in parallel with combustion cavity injecting pressured air before ignition.
        Combinations of air suction and air compression pump provides a rich mixture of oxygen for powerful turbo engine.
        Three different implementation of the Blocker allows for different types of engines with respect to their usages.
        Turbochargers and superchargers are fans that force compressed air into an engine's said cavities. Fans in this case are always open at the air intake side and thus will not produce a high pressure compressed air. That is why they are huge for race car engines.
        Bigger and more powerful engines will be built by enlarging the volume of the cavity and larger radiuses of the cylindrical shape housing. This will eliminate the need for multi piston and cylinders, reducing the number of moving parts and manufacturing costs.
        In the present piston and said cavity engines, crankshafts occupy a major portion of the engine volumes. They are not gear driven and they operate under heavy load. The crankshafts are the sources of friction and generation of heat for eventual failure. This invention does not require crankshaft. A small timed gear assembly is used to activate the Blocker to let the Rotor to pass for no friction.
        The present engine crankshafts operate under a heavy load. They require constant and heavy cooling and lubrication accessories adding more weight to an engine. Due to far lower frictions and moving parts of this invention, the need for lubrication and cooling are far smaller.
        Due to far less moving parts, friction and heat generations, this invention, allows an air cooling system, that is sufficient for cooling an engine with less moving parts and frictions compared to water cooling, further reducing weight and cost of manufacturing of an engine.
        Crankshaft are build heavy to bear the load for the actual motion of a vehicle. The heaviness adds to the size and weight of an engine. The present invention provides for a blade like Rotor and Blocker in which the size and weight are insignificant compared to a crankshaft.
        This invention provides for a dual cycle compressed air pump eliminating an open end air intake side of present turbocharge engines. The same concept of cavity along with a Rotor and Blocker provides for suction and compression pumps that:
        a. A compressed air is injected into the combustion chamber yielding more power output from the combustion chamber.
        Most turbocharged engines us an oversized open end fan to force pressure air into the combustion chamber.
        b. The suction and compression capability of a pump allows greater freedom in design of engines wherein the source and destination of gas or liquid (to and from the engine) will be irrespective of their locations in the vicinity of the combustion chamber.

A variable volume combustion chamber (17) is formed between the Blocker (8) and rotor (7). At the start of a combustion cycle, powdered fuel (14) and pressured air (15) in introduced to the compression chamber (17) and then the spark plug (16) introduces and electrical spark to ignite the mixture. During the ignition, the blast forces the Rotor forward while the Blocker is stationary until the ignited fuel is escaped from the exhaust (20). In the remaining time of the complete cycle, the Blocker moves with faster speed behind the Rotor to get stopped again by the stopped pin (19). The Blocker (8) always trails the rotor (7) to get stopped after the stop pin (19) is inserted into the cylinder. The Rotor passes the stop pin (19) while the stop pin is pulled out and then the Blocker is stopped by the stop pin (19) driven by timer gear assemble (60).

Embodiment 3
Referring now to FIG. 3, for the third embodiment of the circular turbo rotary internal combustion engine (1) for a butterfly Blocker method. It depicts a cylinder shape housing (12), with the shaft (5) centrally rotates in the center of cylinder housing (12). Attached to the shaft (5) is a Rotor (7), rotating radially with the shaft. A semi stationary butterfly Blocker (38) getting circularly inserted in the cylinder (for the duration of the time that combustion is taking place and retracted to let the Rotor pass), through the housing of the cylinder housing (12), or a small housing attached to (12). The center line of rotation of the butterfly Blocker is in parallel with the shaft (5). The butterfly Blocker (38) IS driven by a gear assembly external to the cylinder housing (12). Attached to the cylinder are fuel injection valve (14) air injection valve (15) Spark plug (16) and fuel exhaust (20). The gear assembly is driven by the shaft 5, forcing timed insertion, and retraction of the butterfly Blocker blade (38) inside the cylinder housing (12).
A variable volume combustion chamber (17) is formed between the Blocker blade (38) and rotor (7). At the start of a combustion cycle, powdered fuel (14) and pressured air (15) is injected to the compression chamber (17) and then the spark plug (16) introduces and electrical spark to ignite the mixture. During the ignition, while the Blocker is inside the cylinder, the blast forces the Rotor forward while the Blocker is stationary until the ignited fuel is escaped from the exhaust (20). At the moment of ignition, the combustion chamber is small and is filled with mixture of pressured air and fuel. The ignition forces the rotor forward, rotating the shaft and thus provide rotational power for motion of a vehicle. The fuel injection valve (14) and spark plug (16), each located at proper phase with respect to the rotation of the shaft (5). At the end of the combustion expansion, the exhaust opening (20) lets the exhaust fuels out and the Blocker blade is retracted to let the Rotor (7) to rotate.
Attached to the side of the cylinder housing (12) is provisions of the gear assembly FIG. 3A for the butterfly Blocker. A circular plate (30) attached to the shaft (5) rotates with the shaft outside cylinder housing (12). The butterfly Blocker is attached to the cylinder housing (12) (or a small housing connected to (12)), with the center of rotation at (340) in which the line of rotation is in parallel with the shaft (5).
Referring now to FIG. 3A, when the round plate (30) rotates, its edges are equipped with two segments of (331) and (339). Segment (339) is a round edged semi-circle band in which the outside radius of the band has the same radios of plate (30) and the inside radios of the band is smaller than outer radius. When the plate (30) rotates, the ball bearing (334) makes contact with outer radius of (30) edges or with the inner radius of the band (339). Band (331) is for the portion of the cycle time in which the butterfly Blocker needs to be in closed state inside the cylinder, and no contact during the portion of the cycle time (331). A spring (342) connected to the rod (341) will force the ball bearing (334) to be in contact with either (331) OR (339). When a ball bearing (334) passes near the edge of the band (332), it inserts the butterfly Blocker (38) inside the cylinder and keeps it there till it reaches the edge (333), in which the Blocker (38) is retracted to the side of the cylinder to let the Rotor pass. During the (331) cycle timing a spring (337) forces the rod (340) to get the butterfly Blocker out of the cylinder housing (12) for the Rotor (7) to pass.
1—Single Cycle Compression Pumps.
Referring now to FIG. 4 that depicts a single cycle Compression pump, which is driven by the shaft (5) and a common gear assembly (40) activating both (7) and (18). The air pressure pump works in synchronization with the combustion chamber (1) to deliver pressured air into the combustion chamber (17) at exact timing of the combustion timing period. Note that in the combustion engine, combustion chamber is formed between the Blocker (8) and the Rotor (7). The compression is formed between the Rotor (7) and the Blocker (18). The mechanical construction is similar to the combustion chamber (17) with the same timing gear assembly as in FIG. 1C. The exception is that the valves (14), (15) and (16) are replaced with the air opening (61) and air compression out valve (65). At the start of the cycle, the air already is pushed in into the compression chamber (17). When the Rotor (7) passes the ambient air opening (61) the air will get compressed in front of the R1 while air is sucked in back of in front of the R1. When the Rotor R2 is near the pressured air outlet (61), the pressured air is injected into the combustion chamber (7) via diode valve 65 in time ready for combustion process.
Referring now to FIGS. 4A and 4B that exhibit the phased timed actions of both compressor and the combustion chamber, both driven by the gear assembly (40).
2—Two Cycle Blocker Air compression
Referring now to FIG. 4C, a schematic for describing a combustion chamber (1) a single cycle air pressure pump (2) both using the cycle Blocker described in embodiment 2.
The single cycle air pressure generation pump (2), a Rotor (27) connected to the shaft (5) and a Blocker (28) connected to a the second shaft (4) extended from combustion engine (1), the second shaft (4) rotates freely around the shaft (5) and does not move unless it is driven by gear assembly box (60) that is synchronized to shaft (5). It also includes an air pressure inject diode (21), a stoppage pin (22) and an intake air opening (23)
A variable volume compression chamber is formed between the Blocker (28) and rotor (27), the Blocker (28) trails the rotor (27) and gets stopped at a rotation angle with respect to the rotation of the shaft to provide a timed barrier for the Blocker to be stopped and the rotating Rotor. An air compression chamber (27) is formed between the Blocker at the time that is stopped from moving and the Rotor that is moving towards the Blocker to pressurize air, an air pump. At the moment of compression start, the compression chamber is filled with ambient air with the opening (23). The Blocker is stopped by the stoppage pin (22) from moving forward. The Rotor (27) rotates forward, compressing the air. By the time that the Rotor passes the air intake, the Blocker has to get to the stop pin to start the air compression. The time for acceleration and motion of the Blocker is from the time that the pressured air is forced out through the one way diode 21 to the time that the Rotor has just moved out of the air intake opening 23. The important point is to remember that at the start of the Blocker motion, the rotor is very close to the air inject out (21), and the Stoppage blocking pin 22 is moved up and out of the way of Blocker and the Rotor to pass through.
Engine Embodiment 4

The gear assembly (40) is driven by the shaft (5), forcing timed insertion, and retraction of the Blocker blade (18) inside the cylinder housing (12). An air pressure chamber (27) is formed between the Rotor (7) and Blocker (8). A tank 26 (covered in details in two cycle compression pumps to follow) is added to inject pressured air into the combustion chamber (17) through the air lines (25) and (27). A controlled valve (28) is inserted between the air pressure tank (27) and air pressure valve (16) for proper injection of air into the compression chamber (17).
A variable volume combustion chamber (17) is formed between the Blocker blade (8) and rotor (7). At the start of a combustion cycle, powdered fuel (14) and pre-pressured air that is the result of the previous cycle air compression chamber (27). An electrical spark is introduced by the spark plug (16) to spark and ignite the mixture. During the ignition, while the Rotor rotates inside the cylinder, the blast forces the Rotor (7) forward while the Blocker (8) is stationary. It continues until the ignited fuel is escaped from the exhaust (20). At the moment of ignition, the combustion chamber is small and is filled with mixture of pressured air and fuel. The ignition forces the rotor forward, rotating the shaft and thus provide rotational power for motion of a vehicle. The fuel injection valve (14) and spark plug (16), each located at proper phase with respect to the rotation of the shaft (5).
