Abstract
The invention relates to a filter with automatic cleaning using a hydraulically actuated sprinkling device. According to the invention, a carriage carrying tubes is driven by a hydraulic double-acting actuator. The working chambers of the hydraulic actuator are connected by off-take pipes to the cleaning liquid distributing circuit. Switching members control through the medium of electrically controlled valves the selective entry of the cleaning liquid into the off-take pipes. The device according to the invention can be used in an installation where air filtering is necessary, such as for example an air conditioning installation.
