Abstract: A tool having a housing adapted for connection to a conduit at a remote location and having a first passage extending therethrough and communicating with the exterior of the housing through a discharge opening and a second passage extending through the housing circumventing a portion of the first passage in a by-pass position, and a valve mechanism adapted for connection to the conduit and received within the first passage for movement to and from the by-pass position whereby fluids flow through said second passage and from the discharge opening in the by-pass position and through the conduit through the tool when in a position retracted from the by-pass position.

Abstract: A tool for use in wells having a first assembly with an internal fluid passage and a port interconnecting the exterior of the first assembly and the passage; a mechanism borne by the first assembly for releasably securing the first assembly in a well in a selected position; a housing enclosing a fluid chamber mounted on the first assembly; a second assembly having an end portion received in the fluid chamber for reciprocal movement in pumping relation to and from the first assembly and an opposite end portion adapted for connection to a pipe string in depending relation; and a valve mechanism selectively operable, upon movement of the end portion of the second assembly to the first assembly, to allow fluid movement from the second assembly into the fluid passage of the first assembly and, upon reciprocal movement of the end portion within the fluid chamber, to pump fluid through the port and first assembly into the second assembly and pipe string.
