Rotary cam radial steam engine

A rotary cam radial engine comprising:

• a body, said body have one or a plurality of apertures in a radial orientation therein, each said apertures having a first end of a respective cylinder positioned therein;
• a piston in a respective reciprocating engagement, within each respective said cylinder;
• each said piston having an endwall communicating across a first end of said cylinder and facing toward said first end of said cylinder, and having an attachment end opposite said first end and facing an open end of a said cylinder, said attachment end engaged with a first end of a rod;
• a retaining ring configured for a cooperative engagement with said body to an engaged position;
• said retaining ring having a plurality of radially extending depressions formed therein;
• each respective said depression sized on a first end for a cooperative engagement with an exterior of a respective said cylinder, said retaining ring in said cooperative engagement positioning a said depression in a removable engagement with each said cylinder, said removable engagement maintaining said cylinder, in a fixed position relative to said body;
• each respective said depression configured on a second end, for reciprocation of a respective rod therethrough;
• a cam ring in a circumferential positioning encircling said radially extending depressions;
• said cam ring having an interior circumference defining a race;
• each said rod at a second end, configured for a rolling engagement with said race;
• a respective intake port rotationally positionable to a respective operative communication with a respective first end of each respective said cylinder, at an intake position;
• each respective said intake port at said intake position, providing a communication of a pressurized fluid stream to a respective first end of a respective said cylinder, said communication of pressurized fluid imparting a force to a respective said piston within said respective cylinder, said force imparting a translation of said piston in a power stroke, toward said race;
• said rolling engagement of each respective said rod, sequentially communicating said force against said race, thereby imparting a rotation to said cam ring;
• and
• whereby, said rotation of said cam ring communicated in an operative engagement with a secondary component, such as a pump or generator, provides power thereto for work thereby, said power proportional to a number of said power strokes, per each complete rotation of said cam ring.
