A particle separator for the separation of solid particles out of a flowing fluid, the input mass flow, which is characterized in that a particle chamber for concentrating the solid particles to be separated is disposed in the flow path of the input mass flow and that at least one region of the wall of the particle chamber is implemented as a filter element through which a primary mass flow of the fluid can flow and that, additionally, at least one bypass opening is disposed in the wall of the particle chamber for the through-flow of the fluid with a secondary mass flow at higher filtration resistance.
