Abstract
The instant device for producing a particle cloud in a space particularly at an underpressure comprises a particle chamber (14) with an accommodating compartment (16) provided to hold particles (18), the particle chamber (14) having an inlet and an outlet aperture (20,22). The inlet aperture (20) is coupled to a pressure-wave generating device (28,34) for generating a pressure wave. The pressure wave passes through the inlet aperture (20) into the accommodating compartment (16) of the particle chamber (14) and ejects the particles (18) through the outlet aperture (22).
