    Abstract: A fire hydrant break off valve includes an offset pivot and a lateral trigger captured between a fire hydrant and fire hydrant break off riser. When a collision breaks the break off bolts holding the fire hydrant to the hydrant break off riser, the lateral trigger is released and the valve rotates to a closed position. Force of water attempting to escape rotates the valve around the offset pivot. The edge of the valve is tapered and after rotating, the valve is pushed against a matching seat to close the valve. The match of the tapered valve against the tapered seat stops or nearly stops all flow of water from the broken hydrant.

The base pipe can comprise a finger port, one or more fingers; and one or more hinges, each of the hinges connecting one of the fingers to the base pipe. The sliding sleeve can comprise a sliding sleeve having a first sleeve with in inner surface comprising a void and a depressor. The first sleeve can be positionable in a first position and a second position. In the first position, the depressor can push the one or more fingers into a closed position. In the second position, the void can rest at least one of the one or more fingers, allowing the at least one of the one or more fingers to move into an open position.

  • Patent number: 8522821
    Abstract: A servovalve torque motor includes first and second pole pieces and an armature. Each of the first and second pole pieces includes an armature face that opposes the armature. The area of the armature face of the second pole piece is smaller than the area of the armature face of the first pole piece. The unequal areas of the first and second armature faces create a bias in the servovalve torque motor while allowing the first and second pole pieces to be disposed at equal distances from the armature to define substantially equal air gaps. The inclusion of substantially equal air gaps between the pole pieces and the armature reduces the maximum flux in the armature for the same bias and torque output, compared to conventional servovalve torque motors. The reduction in maximum armature flux decreases armature saturation and improves linearity during operation.

  • Patent number: 8499557
    Abstract: A wastegate for a turbocharger wherein the valve is provided with a horn to provide a more progressive, optimally near linear, curve of turbocharger boost-to-valve opening than possible with the typical flat wastegate valve. The addition of a three-dimensional horn in the flow path is a far more cost-effective solution to acquire linear flow than an approach involving very finite, accurate control of the valve position.

  • Publication number: 20130168588
    Abstract: A valve (e.g., shutoff or regulating) is provided including a valve body having a fluid passage and a disc assembly. The disc assembly is pivotable within the fluid passage from an open position wherein the disc assembly is positioned within the fluid passage to provide for free flow of fluid through the fluid passage, to a closed position wherein the disc assembly is positioned within the fluid passage to substantially close off the fluid passage. The disc assembly includes a disc having a circumferential edge having a groove. A seal (e.g., an O-ring) is disposed in the groove. A pressure relief mechanism (e.g., a plurality of apertures) is provided adjacent to the seal to partially relieve differential pressure on the seal caused by fluid passing through the fluid passage. A similar valve having its seal located on the valve body is also provided.

    Abstract: A thrust recovery outflow valve and method for controlling the transfer of air between a cabin in an aircraft and atmosphere outside of the aircraft are provided. An outflow valve is mounted on the aircraft that includes a valve frame, a first valve door, and a second valve door. The first valve door is rotated to a first predetermined open position while the second valve door is in the second door closed position to thereby open first and second flow passages that place the aircraft cabin in fluid communication with the atmosphere. When the first valve door is at a first predetermined open position, a flap is rotated, relative to the first valve door, to at least partially cover the second flow passage and thereby at least inhibit flow through the second flow passage.

  • Patent number: 8387385
    Abstract: A turbocharger system includes first and second turbines arranged such that exhaust gas passes through the first turbine then the second turbine. A bypass channel is configured such that exhaust gas entering the channel passes only through the second turbine. A valve positioned in the bypass channel regulates the flow of gas therethrough. The valve accelerates a stream of gas and focuses the stream toward the second turbine such that a large part of the added velocity of the stream is preserved as it enters the second turbine. Operation of the valve may be controlled so as to maintain the valve in a closed position while exhaust gas pressure above the first turbine pressure is below a first threshold, to progressively open the valve as the pressure increases above the first threshold, and to maintain the valve in a full-open position while the pressure is above a second threshold.

  • Patent number: 8371103
    Abstract: Valve assembly and method in which a valve member is connected to an elongated lever arm for controlling communication between two chambers in an internal combustion engine. The valve assembly is disposed at least partially within one of the chambers, and the valve member is moved between open and closed by an actuator connected to the lever arm. In some disclosed embodiments, a pilot valve is opened to equalize pressure on both sides of the valve member prior to moving the valve member toward the open position. In others, where a piston in an expansion cylinder is driven by hot, expanding gases from a separate combustion chamber, the exhaust valve is closed before the piston has completed its exhaust stroke, and pressure is allowed to build up in the expansion cylinder to a level corresponding to the pressure in the combustion chamber before the valve member is moved toward the open position.
