Device and method for producing pressure waves of high amplitude

A device for generating pressure waves of high amplitude, comprising:

• a pressure-resistant container;
• a combustion chamber inserted in the pressure-resistant container;
• at least one ignition unit extending into the combustion chamber;
• at least one supply line for supplying a flowable combustible material into the combustion chamber;
• a discharge opening provided in the pressure-resistant container for the directed discharge of gas pressure caused by the ignition of the combustible material in the combustion chamber
• a piston which comprises
• a front section,
• a rear section, and
• a piston seat having a piston surface;
• and
• a spring configured to displace the piston into a starting position;
• wherein the discharge opening has a housing surface opposite to the piston surface,
• wherein the piston is displaceable in its longitudinal direction to close the discharge opening at a closure line and to release the discharge opening for a directed discharge,
• wherein the rear section of the piston is oriented in a direction of the spring,
• wherein the front section of the piston is oriented in a direction of the discharge opening and is arranged in a region of the combustion chamber when the piston is in a position closing the discharge opening,
• wherein, with respect to the longitudinal direction of the piston, the piston surface is inclined obliquely to the discharge opening,
• wherein the housing surface is also inclined obliquely to the discharge opening, and
• wherein, starting from the closure line which is oriented perpendicularly to the longitudinal direction of the piston, an angle is opening, oriented towards the discharge opening, between the housing surface and the piston surface.
