Patent number: 10864613Abstract: 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.Type: GrantFiled: March 31, 2017Date of Patent: December 15, 2020Assignee: OMAX CorporationInventors: Chidambaram Raghavan, John H. Olsen, Douglas Kelley, Olivier L. Tremoulet, Jr., Andre Kashierski, Kevin A. Hay

Patent number: 10010999Abstract: 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.Type: GrantFiled: June 19, 2015Date of Patent: July 3, 2018Assignee: OMAX CorporationInventors: Chidambaram Raghavan, John H. Olsen, Douglas Kelley, Olivier L. Tremoulet, Jr., Rick Marks, Andre Kashierski
