Patent number: 11675376Abstract: A temperature-controlled pressure regulator assembly includes a regulator having a regulator body, a valve seat, an inlet, an outlet, and defines a flow passage connecting the inlet and the outlet. A control element controls the device, a portion of the flow passage extends through a heat chamber, and a heater is positioned to heat the chamber thereby conveying heat to a fluid in the flow passage. A controller is electrically coupled to the heater and is coupled to a power source. A thermal cut-off fuse is coupled to a control circuit, with the thermal cut-off fuse arranged to electrically decouple the heater from the control circuit in response to a temperature exceeding a threshold, thereby deactivating the heater. The thermal cut-off fuse is disposed in a circular fuse holder and positioned adjacent the heater and adjacent a longitudinal center of the heat chamber.Type: GrantFiled: January 22, 2020Date of Patent: June 13, 2023Assignee: TESCOM CORPORATIONInventors: Eric J.

Patent number: 11662039Abstract: A pilot actuated valve assembly includes a valve body having an inlet and an outlet, and includes a main valve, a pilot valve, and a pilot cavity which is at a pilot cavity pressure. A tube houses parts of the pilot valve, and a sleeve engages a portion of the tube, with both being secured to the body by a valve bonnet. The main and pilot valves are coaxial. A solenoid actuator or other suitable actuator is operatively coupled to a shaft of the pilot valve and shifts the pilot valve between the positions. Consequently, the main valve shifts between the closed and open positions in response to shifting of the pilot valve between the closed and open positions.Type: GrantFiled: November 17, 2021Date of Patent: May 30, 2023Assignee: TESCOM CORPORATIONInventors: Jacob T. R. Renollett, Bogdan G. Ungureanu

Patent number: 11566712Abstract: A high pressure fluid control device includes a valve body defining an inlet, an outlet, and a throat disposed between the inlet and the outlet. The valve body defines a longitudinal axis. A valve seat is disposed in the throat and includes a sloped surface. A seat support is disposed in the throat and is adjacent to the valve seat. The seat support includes a sloped surface adjacent to the sloped surface of the valve seat. A control element is disposed in the valve body and includes a stem and a seating surface. The control element is movable between an open position, in which the seating surface is spaced away from the valve seat, and a closed position, in which the seating surface engages the valve seat. The sloped surface of the seat support provides a rigid support to the valve seat to resist deformation of the valve seat.Type: GrantFiled: December 6, 2019Date of Patent: January 31, 2023Assignee: TESCOM CORPORATIONInventors: Jacob T.
