  • Patent number: 11884534
    Abstract: Preloading a containment vessel with Low Vapor Pressure (LVP) liquid; partially evacuating the containment vessel to generate a vacuum in a headspace above the LVP liquid; and relieving material from a process vessel into the containment vessel during a process relief event in the process vessel. The containment vessel pressure may be equalized with ambient conditions prior to preloading the LVP liquid. The containment vessel size and quantity of LVP liquid may be determined to absorb the energy and mass of relieving fluids from the maximum anticipated relief scenario, permitting the gases to condense to liquid form to be recovered in liquid state instead of atmospherically venting or combusting the gases. The containment vessel headspace may be partially occupied with High Vapor Pressure (HVP) liquid comprising C5-C10 hydrocarbons configured to flash during the evacuation step to create and occupy a headspace, providing additional head space volume and heat rejection capacity.

  • Patent number: 11867297
    Abstract: A plug assembly that is configured to secure a plug tip to a valve stem. These configurations may include a clamp that secures to an end of the valve stem. The clamp encloses at least part of the plug tip. In one implementation, the design may include a spring assembly that generates a pre-load on the top of the plug tip, as well. The clamp is useful because it accommodates plug tips made from ceramics and like, brittle materials. Its features can prevent certain mechanical failure, for example, cracks or breaks that can occur during manufacture or assembly. As an added benefit, the device can maintain alignment of the plug tip with the valve stem. This feature can ensure proper engagement with a seat in a flow control, like a control valve.

  • Patent number: 8608127
    Abstract: A control valve has a piezoelectric actuator substantially immersed in a fluid and a sealing mechanism configured to be in a closed position and an open position. The piezoelectric actuator is configured to distort in response to an applied voltage causing the sealing mechanism to transition between the closed position and the open position. In the open position, the sealing mechanism allows fluid to flow therethrough. In response to removing the applied voltage, the piezoelectric actuator returns to an undistorted position causing the sealing mechanism to close and prevent fluid from flowing therethrough. In at least one embodiment, the piezoelectric actuator is configured to contract due to the fluid pressure, and the tube is configured to contract due to the fluid pressure to compensate at least in part for the contraction of the piezoeletric actuator.

  • Patent number: 8578964
    Abstract: The invention relates to a device for bleeding a hydraulic system. The bleeding device comprises a venting passage which can be closed by means of a valve arrangement. In order to simplify such a bleeding device regarding the operation thereof while preventing air from being delivered in an uncontrolled manner during the bleeding process, the valve arrangement is provided with a valve member (S) which can be lifted from a valve seat (8) of the valve arrangement counter to the force of a spring element (7) in an open position of the bleeding device while being fixed to the valve seat (8) in a closed position of the bleeding device. The invention further relates to a venting screw which encompasses such a valve arrangement according to the principle of a check valve and is to be mounted in a caliper (18).

  • Patent number: 7987835
    Abstract: The invention relates to a fuel injector, in particular a common rail injector, for injecting fuel into a combustion chamber of an internal combustion engine. The fuel injector has an injection valve element which is adjustable between a closing position and an opening position and which is switchable by means of a control valve. The control valve has a sleevelike control valve element that is adjustable along an adjustment axis and in its closing position rests sealingly on a control valve seat element. According to the invention, it is provided that the control valve seat element is disposed movably relative to the adjustment axis of the control valve element.

  • Patent number: 7849870
    Abstract: A pressure control valve having a common plenum formed by two flow control valves that each utilize electrically controlled piezoelectric actuators to generate a number of possible operating states and thus control an output pressure from the common plenum formed by the two flow control valves. The flow control valves each have at least one pressure fitting and nozzle, and a nozzle orifice sealing mechanism coupled to the piezoelectric actuator. The piezoelectric actuator may be a piezo-ceramic actuator fixed along one side to a chamber of the flow control valve and having a free side opposite the fixed side. Upon receiving a voltage of a desired magnitude and polarity, the free side of the piezo-ceramic actuator and the nozzle orifice sealing mechanism moves to control a fluid flow into the common plenum. By controllably dithering the piezoelectric actuators, the output pressure from the common plenum may be accurately regulated.

  • Patent number: 7841579
    Abstract: A gimballed valve for a flow control valve operates as a sealing member for an adjustable nozzle and is coupled to a piezoelectric actuator having stacked piezoelectric members that are toroidally shaped. The gimballed valve includes at least two support rings and a center closure member. In one embodiment only an outermost support is in contact with at least one member of the piezoelectric actuator. The support rings may be concentrically arranged and coupled together with flexure members. The center closure member operates to seal against an orifice in the adjustable nozzle and may deflect upon contact with the adjustable nozzle to account for misalignment issues that may arise during machining and/or assembly of the flow control valve.

  • Patent number: 7509971
    Abstract: A fluid control valve includes flexible coupling between a handle and a valve stem which allows the components of the assembly on one side of a wall to be angularly misaligned with the components on the opposing side. Because the components adjacent to the room side of the wall can be mounted perpendicular to the wall, a decorative escutcheon can be mounted flush against the mounting wall when the wall or the valve is out of plumb.

    Abstract: A luer activated device includes an inlet adapted to receive a male luer, an outlet associable with a fluid flow system, and a flow path defined therebetween. The inlet receives a resealable valve element having an aperture adapted to receive the male luer. The valve element is adapted such that a male luer inserted into the aperture will open fluid flow through the inlet without causing a substantial change in fluid displacement.

  • Patent number: 7207346
    Abstract: Provided is a hydrostat for a portable gas range, which prevents the explosion of a gas container by automatically discharging overcompressed gas from the gas container when the inner pressure of the gas container increases to an explosion pressure. The hydrostat includes a body including a gas outlet, which communicates with a gas inlet of the governor valve, and a sealed room, which communicate with the gas outlet. An opening/closing unit is installed within the sealed room of the body such that it can elastically move up and down in order to discharge overcompressed gas by opening the gas outlet when the inner pressure of the gas container reaches or exceeds a threshold value of deformation. A cap is fixed at the bottom of the body so as to support the opening/closing unit and has a discharge hole for discharging overcompressed gas, which escapes the gas container through the gas outlet.
