摘要： The invention is an improved tool for pulling a valve seat from a valve in a fluid end. The invention replaces the standard threaded nut and stem commonly used in such tools with a split nut comprising a plurality of removeably engageable split nut segments placed within a base and a stem configured to be used with the plurality of removeably engageable split nut segments. In the preferred embodiment, each split nut segment possesses a center-facing surface relative to the longitudinal axis of the invention comprising a set of horizontal v-grooves suitable to be disposed against complementary v-grooves of the stem. The base permits the plurality of split nut segments to be placed in an engaged position permitting the v-grooves of the split nut segments to removeably engage the v-grooves of the stem securely or to be placed in a disengaged position. The base containing the split nut segments is durable enough to be used in oil field work but lightweight enough to be used by individual or groups of workers safely.

摘要： This invention pertains to a single-piece unidirectional tapered land thrust bearing cluster for use in high-pressure positive-displacement swashplate piston pumps and the like. The bearing cluster has a plurality of identical bearing pads integral to the bearing cluster. Each bearing pad includes a tapered section, a flat section and a fluid communicating slot integral therewith. During operation of the pump the swashplate camming surface rotates relative to the bearing cluster which develops a pressurized load-carrying hydrodynamic film of decreasing thickness and increasing strength between a back plate of the rotating swashplate and the bearing cluster.

摘要： A positive displacement pump including a plurality of pistons reciprocally driven in respective cylinders by a swashplate assembly to expel fluid during the pressure stroke of the piston from a chamber in communication with each piston. Oppositely disposed magnets are located respectively in an upper pressure face of each piston and in a check valve housing adjacent each cylinder to produce a magnetic force circuit accelerating movement of each piston toward and in continual contact with a cluster bearing associated with the swashplate assembly during the suction stroke of each piston. Like poles of each magnet face each other to produce a permanent levitating force on each piston.
