  • Patent number: 9347594
    Abstract: An hydraulic connection assembly for connecting one or more hydraulic lines may have a one-block body enclosing one or more hydraulic lines and at least one draining line connected to said hydraulic lines. The assembly may also have at least one coupling provided with an axially movable element adapted to actuate a sealing member to allow discharge of fluid pressure and relieve pressure from the tool lines before disconnecting or to facilitate maneuvering of connecting lines. The assembly also reduces the production costs and time, as well as the threes that the operator must apply when engaging pressurized lines.

  • Patent number: 8978693
    Abstract: Disclosed is an inflation valve enabling a user to quickly inflate and deflate an inflatable object. The inflation valve can include an inflation chamber that is an adequate size to capture a breath of air blown by a user from a distance away from an outside opening of the inflation chamber. This allows surrounding air into the area of low pressure created by the moving air, thereby greatly increasing the amount of air entering the inflatable object. To prevent air from escaping the inflatable object, the inflation valve can include a non-invertible one-way valve and/or an invertible one-way valve. Each valve can prevent air from escaping the inflation chamber until adequate pressure is applied from the outside opening of the inflation chamber, for example, as a result of a user blowing air into the inflation chamber. The invertible one-way valve can be inverted to reverse the properties of the valve.

  • Patent number: 8955537
    Abstract: Actuator stem guide apparatus for use with fluid valve actuators are described. An example actuator stem guide apparatus includes a base having an opening to allow an actuator stem of the fluid valve actuator to tilt or lean within the base to enable a lever of the fluid valve actuator to rotate and a guide receiving area adjacent the opening of the base. A guide is coupled to the guide receiving area and the guide has a bearing surface to slidably engage the actuator stem to limit lateral movement of a diaphragm assembly relative to a longitudinal axis of the opening to prevent the diaphragm assembly from engaging an inner surface of an actuator housing as the actuator stem moves between a first position and a second position.

  • Patent number: 8944086
    Abstract: A plumbing freeze protection system comprises a fluid connection between a water supply line and a waste line. The fluid connection bypasses a plumbing fixture fluidly connected to the water supply line. A valve operable with the fluid connection alternately prevents water flow from the water supply line to the waste line, and allows water flow from the water supply line to the waste line within about 25 percent of maximum volumetric flow rate of the water supply line through the fluid connection. A timer is adapted to control the valve. The valve is open for a predetermined time period to deliver a short duration, high volumetric flow rate of water to the waste line to minimize ice formation in, and remove existing ice from, the water supply and waste lines.

  • Patent number: 8944089
    Abstract: A balanced port control assembly includes a control element with a valve plug coupled to a valve stem and a pressure sensing labyrinth defined at least partly by the valve plug. The pressure sensing labyrinth provides for fluid communication between a sealing surface of the valve plug and a balancing diaphragm carried internally of the control element. The pressure sensing labyrinth includes at least one pressure sensing passage extending from the sealing surface and into the valve plug along a central longitudinal axis of the control element. So configured, fluid pressure resident on the sealing surface of the valve plug is also resident on the balancing diaphragm such that equal and opposite forces are applied to the control element.

  • Patent number: 8925566
    Abstract: A method of assuring drop out of a valve assembly comprising detecting a level of a signal from the controller; diverting the signal to a solenoid coil of the valve assembly when the level of the signal is above a predetermined value; and diverting the signal to a load when the level of the signal is below the predetermined value. The level detector may divert the signal away from the coil when the level of the signal is below the predetermined value, thereby ensuring that the coil is fully de-energized in response to the level of the signal being below the predetermined value, while allowing current to flow through the valve assembly, thereby allowing the controller to monitor the integrity of the wiring between the controller and the valve assembly.

  • Patent number: 8905376
    Abstract: Tunable check valves reduce valve-generated vibration to increase the reliability of tunable fluid ends. Selected improved designs described herein reflect disparate applications of identical technical principles (relating to, e.g., the vibration spectrum of an impulse). Tunable check valve embodiments comprise a family including, but not limited to, tunable check valve assemblies, tunable valve seats, and tunable radial arrays. Each such tunable embodiment, in turn, contributes to blocking excitation of fluid end resonances, thus reducing the likelihood of fluid end failures associated with fatigue cracking and/or corrosion fatigue. By down-shifting the frequency domain of each valve-closing impulse shock, initial excitation of fluid end resonances is minimized.
