Rotary cam radial steam engine

A rotary cam radial engine comprising:

• a body, said body having a plurality of locating cavities in a radial orientation therein, each said locating cavity having a first end of a respective cylinder from a plurality of coplanar cylinders, positioned therein;
• a piston in a respective reciprocating engagement, within each respective said cylinder;
• each said piston having a top surface at a first end facing toward said first end of said cylinder, and having a second end opposite said top surface facing an open end of said cylinder, and engaged with a first end of a rod;
• a retaining ring configured for a cooperative engagement with said body;
• said retaining ring having a plurality of radially extending retaining cavities formed therein;
• each respective said retaining cavity 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 said retaining cavity 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 cylinder being individually removable from said engine without removal of other said cylinders by disengagement of said first end thereof from said locating cavity and said exterior thereof from said retaining cavity;
• each respective said retaining cavity configured on a second end, for reciprocation of a said rod therethrough;
• a cam ring in a circumferential positioning encircling said radially extending retaining cavities;
• 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, provides power thereto for work thereby, said power proportional to a number of said power strokes, per each complete rotation of said cam ring.
