  • Patent number: 7980265
    Abstract: A valve for downhole use has the ability to throttle between fully open and closed and is fully variable in positions in between. The valve is preferably responsive to flowing fluid viscosity and uses a three dimensional flow through restrictor in combination with a relatively movable cover. At a given flow, a higher viscosity fluid will create a greater relative movement and make it possible for flowing fluid to bypass more of the flow through member. In a particular application involving production from a zone, an array of such valves can allow more production where the viscosity is higher and less production where the viscosity drops due to, for example, water production.

  • Publication number: 20100095693
    Abstract: A pulse width modulation control is provided for a suction modulation valve in a refrigerant system. An intentional small “leakage” path is maintained through the suction modulation valve to ensure that the pressure inside the compressor shell does not decrease below a safe reliability threshold but, at the same time, does not exceed a certain value, which would cause the refrigerant system to operate inefficiently, when the pulse width modulation control has moved the suction modulation valve to a closed position. The size of this minimum “leakage” path is continuously adjusted to ensure that the optimum pressure inside the compressor shell is maintained regardless of the evaporator pressure and other operating conditions.

    Abstract: A foot pedal evacuates debris and fluid from the field of view of a camera during arthroscopic procedures. In a first embodiment, the foot pedal houses a ball check valve to control fluid flow, and includes a base and a foot support hingedly mounted to one another. The foot support includes a valve actuator that opens the ball check valve by distorting the shape of its valve seat. The ball check valve includes a pair of connectors at the ends of the valve adapted to accept irrigation tubing. The connectors are in axial alignment with one another in a first embodiment and in parallel relation to one another in a second embodiment. A third embodiment eliminates the ball check valve and a spring-loaded lever pinches a tube to prevent fluid flow. Depression of the foot support overcomes the bias of the spring so that liquid fluid flows through the tube.
