  • Patent number: 9708796
    Abstract: A valve for a hydraulic system is provided including a work port channel, a load sense channel, and a tank channel. Additionally, a body cavity extends between the work port channel and the tank channel, and a spool is movably positioned in the body cavity. The body cavity defines an inner surface and the spool defines an outer surface. The inner surface of the body cavity and the outer surface of the spool together define a interface between the body cavity and the spool that extends outwardly from a longitudinal axis, such that an increased pressure differential between the work port channel and a load sense channel increases a sealing force, allowing for a more responsive valve in the hydraulic system with less leakage.

  • Patent number: 8820341
    Abstract: A method is provided to detect the presence of hydraulic line pressure in a hydraulic control system in an electromechanical transmission. The method includes determining an estimated hydraulic line pressure of the hydraulic control system based upon an input flow and an output flow of hydraulic fluid. The input flow and output flow are regulated with a pressure control device, which is energizable on operator demand. A pressure detection device is fluidly connected to the pressure control device to detect the presence of hydraulic pressure. An override module is applied to the estimated hydraulic line pressure to determine a corrected hydraulic line pressure. The override module sets the corrected hydraulic line pressure to predetermined values based on the operating state indicated by the pressure detection device. The override module corrects for an over-estimation of hydraulic line pressure in operating conditions such as low environmental temperatures.

    Abstract: A drain cassette for a dialysis unit has a fluid channel between venous and arterial connection ports, and a valve may controllably open and close fluid communication between a drain outlet port and the venous connection port or the arterial connection port. A blood circuit assembly and drain cassette may be removable from the dialysis unit, e.g., by hand and without the use of tools. A blood circuit assembly may include a single, unitary member that defines portions of a pair of blood pumps, control valves, channels to accurately position flexible tubing for an occluder, an air trap support, and/or other portions of the assembly. A blood circuit assembly engagement device may assist with retaining a blood circuit assembly on the dialysis unit, and/or with removal of the assembly. An actuator may operate a retainer element and an ejector element that interact with the assembly.

  • Publication number: 20140076579
    Abstract: A valve apparatus capable of withstanding high pressures and techniques for using this apparatus in various suitable applications are provided. The valve apparatus typically includes both an upper bellows comprising a standard, convoluted bellows and a lower bellows comprising an edge-welded bellows. The valve apparatus may also include a floating, constant volume fluid chamber that travels with the lower edge-welded bellows as the lower bellows compresses and expands in an effort to protect the lower bellows from very high internal volume fluid pressure.

  • Publication number: 20140053927
    Abstract: An example bypass valve includes a sleeve providing a bore that extends along an axis. The sleeve has at least one window. The bypass valve also includes a spool received within the bore. The spool is configured to move within the bore between a first position that restricts flow through at least one window and a second position that permits flow through the at least one window of the sleeve. An outer diameter of the spool is from 99.90 to 99.95 percent of a diameter of the bore.

  • Patent number: 8656953
    Abstract: A method of preventing a mass flow controller from participating in crosstalk in an array of mass flow controllers is described. The method includes sensing and providing a signal indicative of a fluid pressure inside of a mass flow controller with a pressure sensor contained within the mass flow controller, determining a response of a control valve to a rapid pressure perturbation at the inlet of the mass flow controller using the signal indicative of the fluid pressure to avoid overcompensation for the rapid pressure perturbation, and adjusting a control valve contained within the mass flow controller downstream of the pressure sensor, based on the determined response, so that the mass flow controller avoids overcompensating for the rapid pressure perturbation. The pressure sensor is positioned such that the pressure sensor is sensitive to rapid pressure perturbations at the inlet of the mass flow controller.

  • Patent number: 8616415
    Abstract: A pneumatic dispenser is provided comprising a handle with an actuation arrangement comprising two actuation surfaces, each for actuation by an operator holding the handle to selectively apply pressure to a respective one of the front and rear chambers on either side of a piston couple to a rod for applying a dispensing force, thereby controlling advance and retreat of the rod. Further, a valve is provided comprising a body and first and second moveable members. The valve can be arranged as a space saving five port valve for use in the disclosed dispenser. Additionally, a dispenser comprising a stock portion and a cylinder secured to the stock portion is disclosed. Pressure is supplied to the rear chamber of the cylinder from the stock portion through its front chamber and the piston moveable inside the cylinder.

  • Patent number: 8602055
    Abstract: A hydraulic valve device has a fluid port arrangement (10) with various ports extending at least partially in the valve housing (14), and has a movable control device (18) for at least partially activating the ports. The control device (18) can be acted on at two opposite control sides with a control pressure (XA, XB) of an activation unit (46). A valve device of narrow construction and functionally reliable is created by a media-conducting duct (66) with a guide path extending at least partially as an open duct channel that can be closed off by a cover part or by other housing parts of the multi-part valve housing (14), to conduct the control pressure (XB) from the activation unit (46) to the assignable control side of the control device (18).

  • Patent number: 8591439
    Abstract: An extended term resuscitation system includes a plurality of inflatable cuffs adapted to extend around separate portions of the anatomy of a patient (i.e. the chest, abdomen and legs) for enhancing the circulation when inflated/deflated periodically. A primary low-pressure-high-volume air compressor is in fluid communication with each of the cuffs through individual air handlers. The air handlers are formed with an inflation and a deflation diaphragm valve which, under the control of an electronic timer and a pneumatic circuit, connect the respective cuff to the output of the compressor for inflation or to the atmosphere for deflation. A secondary air compressor provides air under suitable pressure to the pneumatic circuit for the control of the diaphragm valves. As an option the operator may change the cyclical rate and cuff pressure. A ventilator provides oxygen to the patient in selected volumes or on demand.
