Abstract
A Venturi device with a primary flow path and a secondary flow path introduced into the primary flow path, wherein a flow of one or more flowable mediums in the primary flow path and the secondary flow path creates a vortex generating a suction at an inlet of the Venturi device. Systems incorporating the Venturi device in which the primary flow path is charged with energy in the form of thermal energy from the ambient environment through the flow-induced vortex formation. Supercharger systems incorporating the Venturi device, wherein the primary flow of air into an engine is compressed with exhaust gases recirculated through the secondary flow path.

A supercharger system for an internal combustion engine, the supercharger system comprising:
- a Venturi device comprising:
- an inlet configured to receive a primary flow of gas;
- an outlet;
- a body disposed between the inlet and the outlet, the body comprising a converging portion and a diverging portion, the converging portion configured to increase a velocity of the primary flow of gas and decrease a pressure of the primary flow of gas, and the diverging portion configured to decrease the velocity of the primary flow of gas and increase the pressure of the primary flow of gas, wherein the body further comprises a check valve disposed in the converging portion;
- an annular chamber configured to receive a secondary flow of an exhaust gas from the internal combustion engine;
- and
- a secondary input configured to encircle the primary flow and direct the secondary flow from the annular chamber radially inward into the primary flow of gas at a position downstream of the converging portion to create a vortex configured to produce a suction at the inlet to suck the primary flow through the inlet and into the body and to mix the primary flow and the secondary flow together before flowing through the outlet to the internal combustion engine.
A supercharger system for an internal combustion engine, the supercharger system comprising:
- a Venturi device comprising:
- an inlet configured to receive a primary flow of gas;
- an outlet;
- a body disposed between the inlet and the outlet, the body comprising a converging portion and a diverging portion, the converging portion configured to increase a velocity of the primary flow of gas and decrease a pressure of the primary flow of gas, and the diverging portion configured to decrease the velocity of the primary flow of gas and increase the pressure of the primary flow of gas, wherein the body further comprises a check valve disposed in the diverging portion;
- an annular chamber configured to receive a secondary flow of an exhaust gas from the internal combustion engine;
- and
- a secondary input configured to encircle the primary flow and direct the secondary flow from the annular chamber radially inward into the primary flow of gas between the converging portion and the outlet to create a vortex configured to produce a suction at the inlet to suck the primary flow through the inlet and into the body and to mix the primary flow and the secondary flow together before flowing through the outlet to the internal combustion engine.

- an annular chamber configured to receive a secondary flow of exhaust gas from the internal combustion engine;
- and
- a secondary input configured to encircle the primary flow and direct the secondary flow from the annular chamber into the primary flow, between the converging portion and the outlet, at an angle relative to a direction of flow of the primary flow to create a vortex configured to produce a suction at the inlet to suck the primary flow through the inlet and into the body to mix the primary flow and the secondary flow together before flowing to the internal combustion engine.
