    摘要： High pressure pumps and associated check valves for use with, e.g., waterjet systems, are disclosed herein. In some embodiments, high pressure pumps configured in accordance with the present disclosure include check valve assemblies that eliminate threaded parts for restricting the motion of check valve components which are subjected to very high pressure variations at relatively high frequencies. Additionally, embodiments of the pumps described herein can include unitary structures that integrate the individual parts associated with multiple cylinders (e.g., cylinders, check valve bodies, etc.) into a single part (e.g., a cylinder manifold, check valve manifold, outlet manifold, etc.) that can substantially reduce the number of different parts required to assemble the pump.

    摘要： Control valves for waterjet systems, control-valve actuators, waterjet systems, methods for operating waterjet systems, and associated devices, systems, and methods are disclosed. A control valve configured in accordance with a particular embodiment includes a first seat having a tapered inner surface, a second seat having a contact surface, and an elongated pin having a shaft portion and an end portion. The pin is movable relative to the first and second seats between a shutoff position and one or more throttling positions. When the pin is at the shutoff position, the end portion of the pin is in contact with the contact surface. When the pin is at the throttling position, the end portion of the pin is spaced apart from the contact surface and the tapered inner surface and the shaft portion of the pin at least partially define a throttling gap.

    摘要： High pressure pump systems with reduced pressure ripple for use with waterjet systems and other systems are described herein. A pump system configured in accordance with a particular embodiment includes four reciprocating members operably coupled to a crankshaft at 90 degree phase angles. The reciprocating members can include plungers operably disposed in corresponding cylinders and configured to compress fluid (e.g., water) in the cylinders to pressures suitable for waterjet processing, such as pressures exceeding 30,000 psi.

    摘要： Waterjet systems including control valves and associated devices, systems, and methods are disclosed. A waterjet system configured in accordance with a particular embodiment includes a fluid source, a jet outlet, and a fluid conveyance extending from the fluid source to the jet outlet. The system further includes a control valve positioned along the fluid conveyance downstream from the fluid source and upstream from the jet outlet. The fluid conveyance has a first portion upstream from the control valve and a second portion downstream from the control valve. The control valve is configured to controllably reduce a pressure of fluid within the second portion of the fluid conveyance relative to a pressure of fluid within the first portion of the fluid conveyance. The first portion of the fluid conveyance is configured to accommodate movement of the jet outlet relative to the fluid source.
