Rotary Roller Motor

Abstract

The Rotary Roller Motor (RRM) is a four cycle rotary internal combustion engine that uniquely overcomes many of the drawbacks of other rotary type engines, by having the Rotor ‘roll’ around the inside of the engine block, rather than scraping it. This is accomplished with a two part rotor. The inner part of the rotor is composed of a Rotor Shaft (RS-12) with an Offset Circular Lobe (OCL-11) rigidly attached to it. The Outer Rotor (OR-9) fits symmetrically around the Offset Circular Lobe, with Inter Rotor Bearings (IRB-10) between the two to allow free movement. The four cycles are separated by two barriers; the Compression/Power Barrier (CPB-13), and the Exhaust/Intake Barrier (EIB-6). Compression is controlled by two non-reversing barriers, the Non-reversing Compression Barrier (NCB-3) and the Compression Hold Barrier (CHB-14), on either side of the Combustion Chamber (CC-2).

Claims

1. The Rotary Roller Motor (RRM) is a four cycle rotary internal combustion engine that uniquely overcomes many of the drawbacks of other rotary type engines, by having the Rotor ‘roll’ around the inside of the engine block, rather than scraping against it. This is accomplished with a two part rotor. The inner part of the rotor is composed of a Rotor Shaft (RS, item 12) with an Offset Circular Lobe (OCL, item 11) rigidly attached to it, or combining both features as a single machined part. The Outer Rotor (OR, item 9) fits symmetrically around the OCL, with an Inter Rotor Bearings (IRB, item 10) between the two to allow free rotation around the OCL. The four cycles are separated by two barriers; the Compression/Power Barrier (CPB, item 13), and the Exhaust/Intake Barrier (EIB, item 6). Compression is controlled by two other barriers, the Non-reversing Compression Barrier (NCB, item 3) and the Compression Hold Barrier (CHB, item 14), on either side of the Combustion Chamber (CC, item 2).

Description

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS

[0012] Drawings Major Component Index

[0013] FIG. 1: End view showing the basic arrangement of the RRM after ignition, forcing the Rotor (composed of items 9, 10, 11, & 12) to turn (clockwise in this case) while simultaneously pushing exhaust gas from the previous ignition out the Exhaust Port (item 7) and drawing in fresh air through the Intake Port (item 5). Drawing also shows two alternatives to the Compression Hold Barrier (CHB, item 14); symmetrical—shown on the drawing, and asymmetrical (item 14A) —shown in the insert.

[0014] FIG. 2: End view showing the continued rotation of the Rotor approximately 180 degrees clockwise showing the closure of the Compression Hold Barrier (item 14) white the Non-reversing Compression Barrier (item 3) is open allowing the compressed air to enter the Combustion Chamber (CC). This view also shows the exhaust gases freely expelling through the open Exhaust Port (item 7) while air is being draw in through the Intake Port (item 5).

[0015] FIG. 3: Shows a rotational view of the major components with an End Plate (item 15) removed.

[0016] FIG. 4: Shows a typical cut-away side view of the major components.

[0017] FIG. 5: Shows a 3D rotational view similar to the position of the Rotor in FIG. 1.

[0018] FIG. 6: Shows a 3D rotational view of a typical configuration of the Spring Nuts on the outside of End Plate (item 15).

[0019] FIG. 7: Shows a 3D rotational view of the ability to connect several (in this case four) rotors together.
