Beschreibung
Zusammenfassung:	1. Knocking sensor for direct or indirect fastening to an internal-combustion engine, with a piezoelectric disc (14) which is arranged between two contact discs in a housing (10) and on which a seismic mass (16) acts, characterized in that the piezoelectric disc (14), the seismic mass (16) and a cup spring (17) acting on these parts are arranged on a pressure sleeve (11), the bore (28) of which forms a passage for a screw retaining the housing (10) on the internal-combustion engine.
