Abstract
A pneumatic engine includes first and second pneumatic motors. Each motor has a stator, a rotor, and a gas flow path. The rotor is rotatably connected to the stator. The gas flow path is defined at least in part by the stator and the rotor, and extends from a gas inlet to a terminal gas outlet. The gas flow path has an expansion portion extending between the gas inlet and an intermediate gas outlet, and a compression portion extending between the intermediate gas outlet and the terminal gas outlet. The terminal gas outlet of the first pneumatic motor is fluidly connected upstream of the gas inlet of the second pneumatic motor.
Claims7
A pneumatic engine comprising:
- first and second pneumatic motors, each pneumatic motor having
- a stator;
- a rotor rotatably connected to the stator, and rotatable in a rotation direction relative to the stator;
- and
- a gas flow path defined at least in part by the stator and the rotor, the gas flow path extending from a first end to a second end, the first end having a gas inlet, and the second end having a terminal gas outlet, wherein the terminal gas outlet is the farthest outlet and/or inlet from the gas inlet in the rotation direction,
- the gas flow path having an expansion portion extending between the gas inlet and an intermediate gas outlet, and a compression portion extending between the intermediate gas outlet and the terminal gas outlet,
- the terminal gas outlet of the first pneumatic motor fluidly connected to the gas inlet of the second pneumatic motor.
A pneumatic motor comprising:
- a stator;
- a rotor rotatably connected to the stator, and rotatable in a rotation direction relative to the stator;
- and
- a plurality of gas flow paths defined by the stator and the rotor, each gas flow path extending in the rotation direction from a respective gas inlet to a respective terminal gas outlet, wherein the gas inlet and terminal gas outlet of each gas flow path of the plurality of gas flow paths is different from the gas inlet and terminal gas outlet of each other gas flow path of the plurality of gas flow paths;
- wherein the plurality of gas flow paths are fluidly connected in series.
