Abstract
A supercharger for an internal combustion engine includes a supercharger chamber, a diaphragm, an inlet valve, an outlet valve, an exhaust gas line, and an actuator. The diaphragm is positioned in the supercharger chamber and divides the supercharger chamber into an intake chamber and an exhaust gas chamber. The inlet valve and outlet valve are positioned on the intake chamber. The exhaust gas chamber is connected to the exhaust gas line, and to the actuator. The actuator is electrically actuatable, is connected to the diaphragm, and is configured to change a resonance frequency of the diaphragm.

A supercharger for an internal combustion engine, comprising:
- a supercharger chamber,
- a diaphragm positioned in the supercharger chamber so as to subdivide the supercharger chamber into an intake chamber and an exhaust gas chamber;
- an inlet valve and an outlet valve positioned on the intake chamber;
- an exhaust gas line connected to the exhaust gas chamber;
- and
- an electrically operable actuator connected to the diaphragm, and configured to change a resonant frequency of the diaphragm.
