  • Patent number: 12093062
    Abstract: A pressure reducer includes a housing, defining upstream and downstream pressure chambers. A valve is positioned in the housing and includes a diaphragm acting on a valve tappet. The valve includes a valve body fastened to the valve tappet and cooperating with a sealing element. The valve body has a cylindrical, hollow-cylindrical, or conical contour and forms a sealing surface effective in the radial direction. The sealing surface is interrupted at at least one circumferential position by a flow channel, such that, depending on a pressure drop in the downstream pressure chamber, either the sealing element lies against the sealing surface and completely closes a flow region between the sealing element and the sealing surface or the sealing element is removed from the sealing surface and completely opens the flow region or the sealing element lies against the sealing surface and partly opens the flow region exclusively by the respective flow channel.

  • Publication number: 20150020900
    Abstract: A media control valve has a valve body having a media inlet and a media outlet and a plunger which is positioned within the valve body. The plunger is connected to a metering control assembly in the bore of the valve body and can be removed without disturbing the control assembly. A sleeve is positioned in the valve body between the valve body and the plunger. The sleeve includes an integral seal for sealing the valve to a flow device such as a base. The valve stem or post for housing the control knob may have metering marks for visually indicating the position of the plunger relative to the sleeve. The control knob on the valve is aligned with the metering marks on the valve body, whereby the valve opening may be calibrated by visual indication of the alignment of the metering marks with the lower edge of the control knob.

    Abstract: A valve (10) for selectively diverting flow from a source to another path for use in vehicles. The valve includes a valve plunger (20) axially movable in a housing (12) between a closed position in which an annulus (28) of the valve plunger blocks the inner diameter of an inlet pipe (14) and serves as a hydrodynamic surface to move the fluid entering the inlet pipe smoothly over the valve elements, including a control chamber (40) that contacts with a fixed base of the valve member. The control chamber is connected by an inlet orifice (32) to the inlet pressure and to an external control orifice (52) connection having a low-pressure side such that the control pressure in the control chamber is variable between 100% and 0% of the inlet pressure.

  • Publication number: 20150001431
    Abstract: Embodiments of a force generating element that can broaden the application of valves and, in particular, pilot-operated valves to include applications that have extreme operating temperatures. These improvements forgo use of o-rings (and like elastomeric devices) in lieu of more durable and robust seals (e.g., metal-to-metal contact). Rather, as discussed more below, the valves incorporate a force generating element that ensures contact between components to form appropriate seals that allow the cylinder to maintain pressure, despite dimensional changes in the structure of the valve.

  • Patent number: 8899551
    Abstract: A valve assembly includes a valve body having a body recess and a bonnet including a bonnet recess having a bonnet mating surface. The valve assembly further includes a valve cage disposed within an interior of the valve body, the valve cage including a body portion extending along a longitudinal axis and a circumferential mating protrusion extending from an outer surface in a transverse direction, the mating protrusion including an upper mating surface and a lower mating surface. The upper mating surface is disposed within the bonnet recess to be aligned with the bonnet mating surface, and the lower mating surface is disposed within the body recess to be aligned with the body mating surface, wherein the upper and lower mating surface are not parallel. Accordingly, clamping forces acting on the mating protrusion include a longitudinal and tangential component, allowing for increased clamping forces without plastically deforming the mating protrusion.

    Abstract: A valve assembly is provided including a generally hollow cylinder coupled to an axially aligned piston chamber. The cylinder defines an internal void extending from one side of the cylinder to another side of the cylinder. The cylinder includes at least one fluid inlet path and at least one fluid outlet path. A shuttle is arranged within the internal void of the cylinder. The shuttle is slidable between a first position and a second position around an axially located piston rod of the piston chamber. A generally sealed chamber exists between a portion of the shuttle and the cylinder. When the shuttle is in the second position, the chamber fluidly couples the fluid inlet path and the fluid outlet path to provide a controllable fluid flow into and out of the cylinder.

  • Publication number: 20140318639
    Abstract: An apparatus, system and method for regulating fluid flow are disclosed. The apparatus includes a flow rate sensor and a valve. The flow rate sensor uses images to estimate flow through a drip chamber and then controls the valve based on the estimated flow rate. The valve comprises a rigid housing disposed around the tube in which fluid flow is being controlled. Increasing the pressure in the housing controls the size of the lumen within the tube by deforming the tube, therefore controlling flow through the tube.
