Abstract

For an audible alarm, a rotor with radially projecting paddles turns about an eccentric axis within a cylindrical chamber. A central cylindrical light alloy body contains an eccentric cylindrical chamber with a steel tube wall, and has 2 circular lids, upper and lower of light alloy, with at least their surfaces at the level of the chamber coated with PTFE. One lid can be pressed toward the other with the body between; at least one lid has a central bore for the shaft keyed to the rotor.
