Abstract

The present invention relates to a filter drill rod for a hydraulic down-the-hole hammer. The drill rod comprises a first fluid flow channel through the drill rod; and a second fluid flow channel through the drill rod. The drill rod also comprises at least one filter disposed in the first fluid flow channel. The drill rod is configured to permit pressure fluid to flow in the first fluid flow channel and return fluid to flow in the second fluid flow channel, or pressure fluid to flow in the second fluid flow channel and return fluid to flow in the first fluid flow channel. The filter drill rod may further comprise means for selectively placing the first and second fluid flow channels in fluid communication with one another at a point downstream of the filter. The invention also relates to a filter cleaning valve component for connection in a drill string of a hydraulic down-the-hole hammer downstream of a filter drill rod. The valve component comprises a first fluid flow channel through the valve component and a second fluid flow channel through the valve component. The valve component further comprises means for selectively placing the first and second fluid flow channels in fluid communication with one another.
