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.
