    Abstract: A pressure relief valve system for a fluid injection system is provided. The pressure relief valve system comprises one or more pressure transducers configured to sense fluid pressure within the fluid injection system.

    Abstract: A high pressure seal assembly for connection to an upper and lower connector pipe. The seal assembly includes a lower seal assembly surrounding a lower end of a rotating pipe, e.g., a washpipe. The lower seal assembly includes a first and second seal ring that define an annular space. The seal rings have a simple cross-section and are identical, thereby facilitating ease of manufacture and assembly. High pressure seals are received within annular spaces of the respective seal rings. The high pressure seals define inner surfaces that have a layer of self-lubricating polymer for engaging the rotating pipe. The high pressure seals define a pressure facing cavity that receives a high pressure ring that mitigates the spreading of the body of the high pressure seals due to pressure and that prevents the seal from extruding through an adjacent gap. An excluder seal prevents debris from entering the seal assembly.

    Abstract: A hydraulic cylinder includes a cylinder having axially spaced-apart first and second bores, and a piston having a piston rod and arranged in the cylinder for movement between two end positions and dividing the cylinder into a piston side and a piston-rod side. A hydraulic pump pumps hydraulic oil into the piston side to move the piston from one end position toward the other end position while hydraulic fluid is discharged from the piston-rod side via the first bore and a first outlet line. A throttling device is operably connected to the cylinder to throttle a flow of the hydraulic fluid as the piston moves past and seals the first bore so that hydraulic fluid is discharged via the second bore, thereby reducing a delivery amount of the hydraulic oil and thereby braking and damping a movement of the piston toward the other one of the end positions.

  • Patent number: 10131192
    Abstract: A central tire inflation/deflation system (CTIS) with a novel valve that may deflate more quickly and may deflate to a lower pressure than the previously known central tire inflation/deflation system valves. Also, the present valve may not be temperature sensitive, at least because the present valve does not require trapped air behind a diaphragm to operate the valve. The present valve may be placed into existing CTIS's in place of existing valves, without modifying pneumatic lines of the existing CTIS's. Thus, the present valve may be operated by a single fluid flow line, receive pressure from the single fluid flow line, and exhaust to the single fluid flow line. A second communication line, either a pneumatic pilot line or an electrical line, is not necessary, which allows the present valve to be retrofit into an existing CTIS without adding weight or complication from additional components.

A regeneration deactivation valve can react to a differential pressure when the function is in free air and at risk of cavitating or when then function is doing positive work and needs to be efficient. When the function is at risk of cavitating, the regeneration deactivation valve can react to the potential for cavitation and the regeneration deactivation valve closes so the function regenerates. The regeneration deactivation valve can also react when the function is not at a risk of cavitating and can open up allowing the function to move with more power and efficiency.

  • Patent number: 9919126
    Abstract: A pressure regulating device for use with a breathing assistance and/or resuscitation apparatus, which conveys gases along a gases pathway to a patient, includes a mounting for connecting the pressure regulating device to a first outlet in fluid communication with the gases pathway. The mounting holds a valve member that selectively blocks, at least in part, the first outlet. A control member can be manipulated to adjust a property of the valve member. The valve member at least partially blocks the first outlet when the pressure of gases in the pathway is below a selected level, and allows at least a portion of the gases to flow out of the first outlet when the pressure of said gases is above the selected level. The property includes a selected level of pressure whereby manipulation of the control member adjusts the level of pressure between a maximum level and a minimum level.

  • Patent number: 9909294
    Abstract: A backflow inhibitor has a jet nozzle connectable to a flow entrance and has a capture part which captures the liquid jet that passes over a free jet path from the jet nozzle. The capture part is connectable or connected to a flow exit and to an outlet arranged below the free jet path. The outlet discharges a partial amount of liquid not captured by the capture part. The backflow inhibitor includes an insert cartridge which carries the jet nozzle and the capture part. In use, the insert cartridge is held such that the jet nozzle is connected to the flow entrance and the capture part is connected to the flow exit. The insert cartridge, in the cartridge section which is arranged between jet nozzle and capture part and which forms or delimits the free jet path, has at least one cartridge opening that can be connected to the outlet.

  • Patent number: 9771935
    Abstract: A variable displacement vane pump has a control slide displaceable within its housing and a first control chamber and a second control chamber for receiving pressurized lubricant. A thermally adjustable control valve is provided in the housing for adjusting pump displacement based on a temperature of the lubricant. In addition to fluid communication channels in the control chambers, at least one vent port is provided in the second chamber. The control valve is configured to control pressure and fluid communication between the chambers along with the control slide. The control valve can help reduce pump displacement at lower temperatures and low engine speeds. At lower temperatures, the second control chamber can be pressurized by the first control chamber. At higher temperatures, the second control chamber can be vented through the control valve and/or the vent port, despite the position of the control slide.

  • Patent number: 9725995
    Abstract: Applicants have created systems, methods, and apparatuses for increasing the production of fluid from a subterranean well. The system can include a controller and upper and lower portions. The upper portion can include an injection valve for regulating the amount of a first gas injected into an injection conduit. The lower portion can include a chamber valve for regulating the flow of a second gas through an upper tubing string and a vent valve for regulating the flow of the first gas and a standing valve. The collected fluid creates pressure in the lower portion causing the second gas to flow from the lower tubing string to the upper tubing string. The controller controls the injection valve and is coupled to a pressure gauge for measuring pressure in the lower portion. With the aid of this system, well operators can increase production of subterranean well formations, such as gas wells, without increasing backpressure on those formations.
