Abstract: A fluid end for a reciprocating pump including a body having a base, a side and a longitudinal opposing side, a cylinder bore formed horizontally through the body and a vertical bore intersecting the cylinder bore defining a high stress region proximate the intersection, and a tension member extending through the body substantially parallel to the longitudinal axis of the body, wherein the tension member provides a compressive load on the body reducing the stresses encountered in the region during operation of the fluid end.

Abstract: A plug valve is provided that may be lubricated while in service. The invention provides a high-pressure valve having a valve body containing a plug allowing bi-directional flow and moveable between an open and closed flow-through position. The valve permitting lubricating and sealing while in-service and in the closed or open position. The lubricating and/or sealing mechanism includes channels formed through the plug to a lubricant groove or grooves formed on the outside surface of the plug between the ends of the fluid conduit through the plug for directing lubricant to the plug-insert or plug-valve body interface when the plug is in the closed position and lubricant to the relief area formed by the insert when the plug is in the open position.
