ABSTRACT:
A filter used in irrigation systems comprises a hollow screening and filtering body with inlet and outlet ports. A Venturi pipe is connected with the interior of said body. The screening and filtering body is placed in a casing which has an outlet. A conduit leads from the interior of the screening and filtering body into a container. From the interior of that container a further conduit leads to a point substantially co-incident with the throat of the Venturi pipe. The said further conduit is closed at its end positioned within the container. That portion of the said further conduit which extends within the container is permeable to liquid. The container has a flushing inlet and a flushing outlet.
