    Abstract: In one aspect of the present invention, a system for a downhole string comprises a fluid path defined by a bore formed within a tubular component. A reciprocating valve is located within a wall of the bore hydraulically connecting the bore with a fluid passage. The valve comprises a substantially cylindrical shaped housing. First and second ports are disposed on a circumference of the housing, and a fluid pathway is disposed intermediate the first and second ports. The valve comprises an axially slidable spool disposed within and coaxial with the housing and comprises a blocker. The blocker is configured to slide axially so to block and unblock the fluid pathway to control a flow from the bore to the fluid passage. The valve comprises a plurality of seals. Each seal is disposed opposite of the blocker causing pressure to be equally applied to the blocker and the plurality of seals.

    Abstract: In one aspect of the present invention, a crawler system for an earth boring system comprises at least two expandable tools along a common axis and spaced apart from each other along the common axis by a piston cylinder device. The at least two expandable tools comprise a mandrel comprising a tubular body and an outer diameter, a plurality of blades, and a slidable sleeve capable of manipulating the plurality of blades into collapsed and expanded positions. The plurality of blades of one of the at least two expandable tools expand to an expanded position and engage a borehole wall. The piston cylinder device anchors against the engagement between the borehole wall and one of the at least two expandable tools to axially translate the other of the at least two expandable tools.
