  • Publication number: 20200362751
    Abstract: The present invention refers to a multi-stage turbocharger unit for an internal combustion engine, comprising an intake passage for supplying charged intake air to the engine having a first and a second compressor which are fluid-communicatively connected via an interstage duct, and a bypass valve configured to supply intake air into the interstage duct by bypassing the first compressor when an interstage pressure prevailing in the interstage duct falls below a threshold value.

  • Patent number: 10774796
    Abstract: A valve assembly comprises: a valve housing comprising an interior cavity having upstream side and a downstream side; and a valve member movable within the valve housing between a closed position in which flow between the upstream side and the downstream side is prevented or substantially prevented and one or more open positions in which flow between the upstream side and the downstream side is enabled. The valve assembly further comprises: a sensor mounting flange on an exterior surface of the valve housing; a first bore in the valve housing linking the upstream side of the valve housing and the sensor mounting flange; and a second bore in the valve housing linking the downstream side of the valve housing and the sensor mounting flange; such that a sensor configured to measure a differential between the upstream side and the downstream side is mountable directly on the valve assembly.

  • Patent number: 4083538
    Abstract: A pressure vessel base closure means including a pair of flat disc-like members spaced apart by a peripheral outer cylindrical member and an inner perforated cylindrical member, and there being provided between the two flat disc-like members a plurality of radially directed ribs to provide rigidity to the base closure means. The base closure means is particularly useful for a reactor in which a bed of fluidized solid is maintained by the passage of a gas into the reactor through the base via the chamber between the two flat disc-like members.

  • Patent number: 4076200
    Abstract: A supported vessel having a number of outwardly directed projections on the side of the vessel which are fixed to the outer end of horizontally disposed webs, the inner end of the webs being supported on a supporting structure, the lower end of which is secured in the ground, the weight of the vessel being transmitted to the webs through the support structure. The invention also claims a support for such a supported vessel.

  • Patent number: 4023597
    Abstract: A gas distributor tube formed from a non-porous ceramic material having a generally axial passageway at least part of which is in the form of a helix. A treatment chamber or reactor is provided with a number of distributor tubes located in the base of the chamber to permit the introduction of a gas through the passageway of this distributor into the treatment chamber in which a solid material in finely divided form may be maintained in fluid suspension.
