Rotary gas pressure engine system

A rotary gas pressure engine system comprising:

• a housing having first and second housing plates separated by first and second spacer rings;
• a cam ring having upper and lower halves carried in said housing between the first and second spacer rings;
• said cam ring having generally elliptical risers positioned along its inner periphery;
• a stationary shaft extending through said housing plates;
• said stationary shaft including aligned intake and exhaust tubes and having a closure member therebetween;
• a circular cylinder block rotatably mounted on said stationary shaft and extending over the adjacent interior ends of said intake and exhaust tubes;
• said cylinder block including a plurality of radial piston cylinders formed therein;
• each of said plurality of piston cylinders including an intake and an exhaust port in the inner ends of said piston cylinders and respectively positioned around said shaft intake and exhaust tubes;
• said intake tube including intake ports for aligning with said intake ports of said piston cylinders;
• said exhaust tube including exhaust ports for aligning with said exhaust ports of said piston cylinders;
• a plurality of pistons mounted for slidable movement within said piston cylinders;
• said pistons including means for contacting said risers of said cam ring such that said intake ports and exhaust ports in said intake and exhaust tubes are arranged to extend said pistons against said cam risers on power strokes and to exhaust said piston cylinders on exhaust strokes;
• a drive shaft connected to said cylinder block and extending through one of the housing plates;
• said drive shaft being tubular and concentrically positioned around said stationary shaft and adapted for rotation therearound;
• a gas generator for supplying gas to said cylinder block to cause movement of said pistons and rotation of said cylinder block;
• and
• a pump within said housing and rotatable with said cylinder block for pumping fluid to said gas generator.

A rotary gas pressure engine comprising:

• a housing;
• a stationary shaft extending through said housing;
• said stationary shaft including aligned intake and exhaust tubes and having a closure member therebetween;
• a circular cylinder block rotatably mounted on said stationary shaft and extending over the adjacent interior ends of said intake and exhaust tubes;
• said cylinder block including a plurality of radial piston cylinders formed therein;
• said cylinder block further including a circumferentially mounted cam ring having generally elliptical risers around its inner periphery;
• each of said plurality of piston cylinders including an intake and an exhaust port in the inner ends of said piston cylinders and respectively positioned around said shaft intake and exhaust tubes;
• said intake tube including intake ports for aligning with said intake ports of said piston cylinders;
• said exhaust tube including exhaust ports for aligning with said exhaust ports of said piston cylinders;
• a plurality of pistons mounted for slidable movement within said piston cylinders;
• said pistons including means for contacting said risers of said cam ring such that said intake ports and exhaust ports in said intake and exhaust tubes are arranged to extend said pistons against said cam risers on power strokes and to exhaust said piston cylinders on exhaust strokes;
• drive means connected to said cylinder block;
• a gas generator for supplying gas to said cylinder block to cause movement of said pistons and rotation of said cylinder block;
• said housing further including a pump rotor mounted to said block for rotation therewith and having a plurality of substantially radial slots;
• a vane mounted within each of said plurality of substantially radial slots for slidable movement therein between a fully extended position and a fully retracted position;
• said housing further including a casing mounted normal to said shaft and adjacent said rotor to enclose said vanes;
• said casing having an internal eccentric bore such that when said rotor is rotated said vanes are caused to slide within said slots between said fully extended and retracted positions in a radial direction by contacting the periphery of said eccentric bore;
• and
• said casing further including a fluid intake port and a fluid discharge port such that said fluid is trapped between said vanes in said fully extended position when said vanes are rotated past said fluid intake port, said fluid is carried around said casing and is forced out through said fluid discharge port as the eccentricity of the casing causes the radial extension of said vanes from said slots to slide to said fully retracted position thereby permitting said fluid to discharge from said casing through said fluid discharge port.
