Abstract
The invention relates to an internal combustion vibrator for compacting concrete, comprising a vibrator housing in which a rotational unbalance mass, an electric motor powering said unbalance mass and part of a power line connected to the electric motor for supplying power to said electric motor are integrated. The internal vibrator also comprises an interrupter interconnected in the power line for interrupting power supply of the electric motor. Due to the fact that the interrupter is configured in an electrically controllable manner, power supply of the electric motor can be precisely controlled by a plurality of signal transmitters.
