  • Patent number: 11255252
    Abstract: A radial compressor has an iris diaphragm mechanism for a pressure-charging device of an internal combustion engine. The radial compressor has a bearing assembly, in which a rotor shaft is rotatably mounted, having a compressor impeller arranged in a compressor housing for conjoint rotation on the rotor shaft and having a fresh air supply channel for carrying a fresh air mass flow to the compressor impeller. The iris diaphragm mechanism is upstream of the compressor impeller, allowing variable adjustment of a flow cross section for the fresh air mass flow for admission to the compressor impeller, at least over a partial region. For this purpose, the iris diaphragm mechanism has multiple lamellae which each have a plate style lamella main body and a pin style actuating element as integral constituent parts of the respective lamella.

  • Patent number: 10570905
    Abstract: A centrifugal compressor for a turbocharger includes an inlet-adjustment mechanism in an air inlet for the compressor, operable to move between a closed position, an open position, and a super-open position. The compressor also includes a ported shroud system. The inlet-adjustment mechanism includes a plurality of blades disposed about the air inlet and movable radially inwardly and outwardly for defining the various positions. In the closed position, the effective diameter of air inlet is reduced and the blades block flow through the ported shroud system. In the open position, the blades still block the ported shroud but the effective inlet diameter is increased relative to the closed position. In the super-open position, the blades unblock the ported shroud so that an additional amount of flow can pass through the ported shroud, thereby shifting the compressor's choke flow line to higher flow rates.

    Abstract: A forward check valve and a fuel cell system in which fluid control is performed with increased reliability when a highly active fluid is used are structured such that when an edge portion of a cap is joined to an edge portion of a valve housing, a peripheral edge portion of a diaphragm is pushed and sandwiched by a peripheral edge portion of the cap and a placement portion. Further, the diaphragm is formed of rubber. As a result, the peripheral edge portion of the diaphragm is compressed by the peripheral edge portion of the cap and the placement portion, so that the degree of contact at a contact portion between the placement portion and the peripheral edge portion of the diaphragm becomes very high. Consequently, in the forward check valve, joints of the members including a joint of the edge portion of the cap and the edge portion of the valve housing do not contact methanol.

  • Patent number: 8387950
    Abstract: A flow device adapted to operate as a restrictor as well as provide a pressure relief capability in the event of an over-pressurization event within a fluid system containing the device. The flow device includes an expandable orifice that has an outer perimeter, a plurality of cantilevered tabs surrounded by the outer perimeter, and an opening surrounded and defined by the tabs. The tabs project from the outer perimeter toward the opening, which restricts flow of the bleed air through the expandable orifice at a pressure below a predetermined pressure level, but then expands to relieve an over-pressure condition of the bleed air at a pressure above the predetermined pressure level as a result of the cantilevered tabs being deflected by the over-pressure condition. The device is adaptable for use in aircraft applications, including the regulation of bleed air used in anti-icing/de-icing systems.

  • Patent number: 8132783
    Abstract: In a fluid transmission line, a valve comprising a housing that establishes a lumen for transmission of a fluid through said valve; a drive mechanism and a drive gear mounted in said housing to be selectively driven in a first or second rotational direction by said drive mechanism. The drive gear has a central throughhole and a plurality of pins around the central throughhole. A plurality of leaves are pivotally mounted on the pins, and oriented to extend radially inward into said central throughhole. A fixed extension has an annular aspect disposed in the drive gear, and has a plurality of engagement members disposed to operatively engage one of said leaves. The engagement members bias the leaves to close an orifice when said drive gear rotates in said first direction and to open the orifice when said drive gear rotates in said second direction.

  • Patent number: 8122911
    Abstract: A variable orifice for use in connection with a conduit designed to convey particulate material comprising a set of semi-circular plates mounted on respective concentric shafts so that they may be rotated in opposite directions between a first position in which they extend across the interior of the conduit for maximum flow resistance to a second folded condition where they are adjacent and parallel to one another to present minimum flow resistance. An actuator is connected through the concentric shafts to the plates and mounts on the outside of the conduit surface. The unit is operated by hand crank and has a position indicator. The size of the valve plates is such that, even when fully extended relative to one another and lying across the cross-section of the conduit, only about a 30% restriction is produced.
