Abstract
A lightweight rotary engine of novel design having a sealed inner portion that allows the engine to assume any attitude during operation. The bottommost portion of each piston contains a bearing roller that is urged against a fixed eccentric post which causes rotation of the rotor assembly. There is no direct connection between the bottommost portion of the pistons and the eccentric post. The rotor consists of a pair of opposed plates for moving the cylinders in a radial direction. The space between the cylinders contains air chambers for holding air under pressure that is used to scavenge the cylinders.
Claims3
A rotary engine comprising:
- a fixed housing defining an interior space having a central axis,
- a fixed post attached to said housing and extending into said space, said post being offset from said central axis,
- a rotor including a pair of opposed plates rotatable within said housing, said rotor including a plurality of independent pistons each having a bearing on the bottommost portion for bearing and rolling about said post whereby actuating the pistons causes the rotor to rotate,
- each piston is disposed to reciprocate radially in a cylinder rotatable with said rotor and located between said opposed plates,
- similar air chambers for holding air under pressure located between said plates and disposed between said cylinders and rotatable as said rotor rotates,
- a rotary output shaft projecting through said housing and attached to said rotor, said output shaft being coaxial with said central axis,
- a centrifugal blower having extending vanes directly attached to said output shaft and mounted directly on the outside of said housing, and
- a rotating valve having a plurality of ports one for each chamber and attached to said rotor for providing a passageway from said blower to each of said chambers sequentially for charging each of said chambers with air under pressure.
