摘要： In accordance with the teachings of the present invention, a flexible coupling assembly installed between a driving member and a driven machine or device. The flexible coupling assembly includes a one-way over-running clutch mechanism incorporated therein and transfers torque from the driving member to the driven device, while compensating for any angular and offset misalignment between two coupling members. The clutch mechanism provides driving torque in one rotational direction and over-running capability in the other, thereby accommodating large torque fluctuations from the driving member. This clutch mechanism is integrated within an intermediate housing assembly that is easily coupled between two jaw-type shaft couplings. Because the present invention eliminates the need for an intermediate shaft between the flexible coupling and a separate clutch mechanism, it further simplifies the installation of the assembly while reducing the overall space required.

摘要： A front-discharge fluid end for a reciprocating pump. The fluid end is distinguished by an outlet valve which is positioned substantially coaxially with the pump plunger and generally facing a longitudinally outer end thereof. The outlet valve is held in place by a valve retainer which includes an outlet port and is connectable to an outlet line. For retrofitting prior pump cylinders, a plug assembly is disclosed for plugging the original outlet valve pocket.

摘要： A modular fluid end assembly, and associated method of providing same, for a reciprocating pump having a cylinder housing secured to a crankcase by tie bolts. The fluid end is tolerant to having cylinder-head bolts improperly torqued while also providing an over pressure relief feature. The modular fluid end includes a cylinder-head having two seal landings, one common to a cylinder base joint surface and one common to an end joint surface. The base joint seal landing is smaller than the end joint seal landing. An end plate and a co-acting valve cover is provided. The valve cover includes a seal extending thereabout and is accommodated by the seal landing of the end joint. A second seal is accommodated by the base joint seal landing. A plurality of cylinder-head bolts having predetermined yield strengths, are located in proximity to the periphery of the end plate to force the end plate and the valve cover against the cylinder-head. Upon an over-pressure condition, the bolts yield thereby allowing the end plate to move away from the cylinder-head and the larger end joint seal ruptures prior to the base joint seal, thereby allowing the fluid or slurry being pumped to flow between the end plate and the cylinder-head thereby preventing damage to the more difficult to repair cylinder housing, while protecting expensive power-end components from being damaged by the overload condition.
