Abstract
A fluid distributor device is for a percussive drill assembly including a generally tubular casing () having a longitudinal centerline and a piston () disposed within the casing so as to define a reservoir chamber () in the casing. The distributor device comprises a generally cylindrical body () disposed within the casing and including a central axis, two opposing ends spaced apart along the axis, first and second interior chambers and a port fluidly connecting the two chambers. The body further has a plurality of fluid passages extending between the two ends and fluidly connecting the first chamber with the reservoir chamber and a deflectable retainer portion () releasably engaged with the casing so as to retain the body at a desired position with respect to the casing centerline. A valve () is disposed within the body and is configured to permit fluid flow through the port and to alternatively prevent fluid flow through the port.
