Abstract
A foam generator, in particular for a motor vehicle washing installation, includes a foam generation chamber having at least one inlet for water, surfactant and gas, in particular compressed gas, and one outlet for foam, and contains a fluid-permeable bed of loose particles. The bed fills the foam generation chamber sufficiently to prevent fluidization of the bed.
