Abstract

Radial impulse engine, pump, and compressor systems are disclosed herein. In one embodiment of the invention, a radial impulse engine includes first and second movable V-members operably disposed between first and second end wall portions. The first V-member can have a first wall portion with a first distal edge portion and a second wall portion with a first cylindrical surface. The second V-member can have a third wall portion with a second distal edge portion and a fourth wall portion with a second cylindrical surface. In this embodiment, the first distal edge portion of the first wall portion can be configured to slide across the second cylindrical surface of the fourth wall portion, and the second distal edge portion of the third wall portion can be configured to slide across the first cylindrical surface of the second wall portion, when the first V-member pivots about a first pivot axis and the second V-member pivots about a second pivot axis.

Claims

1. An engine comprising:

a first movable member configured to rotate about a first pivot axis, the first movable member having a first distal edge portion and a first curved surface;

a second movable member operably coupled to the first movable member to at least partially define a combustion chamber therebetween, the second movable member configured to rotate about a second pivot axis and having a second distal edge portion and a second curved surface;

means for introducing an air/fuel mixture into the combustion chamber;

means for igniting the air/fuel mixture in the combustion chamber to drive the first movable member in rotation about the first pivot axis and the second movable member in rotation about the second pivot axis, as the first distal edge portion slides across the second curved surface and the second distal edge portion simultaneously slides across the first curved surface; and

means for exhausting the ignited air/fuel mixture from the combustion chamber.

2. The engine of claim 1 wherein the first movable member includes a swept wall portion and a compression wall portion, wherein the swept wall portion projects outwardly from the first pivot axis in a first direction and the compression wall portion projects outwardly from the first pivot axis in a second direction, and wherein the swept wall portion carries the first curved surface and the compression wall portion carries the first distal edge portion.

3. The engine of claim 1:

wherein the first movable member further includes a third distal edge portion spaced apart from the first distal edge portion and a third curved surface spaced apart from the first curved surface,

wherein the second movable member further includes a fourth distal edge portion spaced apart from the second distal edge portion and a fourth curved surface spaced apart from the second curved surface, and

wherein the third distal edge portion slides across the fourth curved surface and the fourth distal edge portion simultaneously slides across the third curved surface, as the first movable member rotates about the first pivot axis and the second movable member rotates about the second pivot axis.

4. The engine of claim 1, further comprising means for synchronizing movement of the first and second movable members.

5. The engine of claim 1, further comprising means for converting pivotal motion of the first and second movable members into rotational motion of an associated shaft.

6. The engine of claim 1 wherein the first movable member pivots back and forth about the first pivot axis and the second movable member pivots back and forth about the second pivot axis, as the first distal edge portion slides across the second curved surface and the second distal edge portion simultaneously slides across the first curved surface.
