Axial Inlet For Pumped Fluid Patents (Class 417/71)
  • Patent number: 11209023
    Abstract: A gas compressor comprising a drum affixed to a rotating shaft, the drum including a plurality of compression channels between a common pressure zone and an interior surface of the drum distal to an axis of rotation. A static vane return assembly adjacent the compression channels includes vanes extending from an inlet at an outer circumference to the common pressure zone and directing gas into the common pressure zone, either through the vanes or via separate channels or ducts. Fluid inside the rotating drum forms an annular lake that is drawn through the vanes and into the common pressure zone. Fluid is then forced into the compression channels where gas in the fluid is compressed as it travels from the common pressure zone toward the interior surface. The pressurized gas is separated from the liquid prior to leaving the compression channel assembly while the liquid is returned to the lake.

  • Patent number: 8226376
    Abstract: A pressure exchanger for transmitting pressure energy from a first fluid flow to a second fluid flow includes a housing having an entry and an exit for the first fluid flow and an entry and an exit for the second fluid flow. A rotor arranged in the housing includes a multitude of channels which extend radially distanced to a rotation axis of the rotor. The rotor is arranged to the entries and exits in a manner such that the channels, on rotation of the rotor, in each case in an alternating manner, connect the entry for the first fluid flow to the exit for the second fluid flow, and the entry for the second fluid flow to the exit for the first fluid flow, and with a drive motor via which the rotor may be driven in rotation, and with setting means for changing the rotational speed of the rotor.

  • Patent number: 7097432
    Abstract: A turbocharger having a variable geometry turbine inlet incorporating a cylindrical piston movable to vary the area of the inlet nozzle into the turbine. Vanes mounted to the piston for flow control in the nozzle are received through a slotted heat shield which provides smooth aerodynamic flow into the turbine blades. The vanes additionally incorporate a step having larger cord and depth that engages the surface of the heat shield and seals the slots with the piston in a closed position. An axial actuator is attached for operation of the piston.

  • Patent number: 6641369
    Abstract: The liquid ring compressor comprises a cylindrical casing containing an impeller the axis of which is offset from the axis of the cylindrical casing. At least one end of the cylindrical casing is provided with a distribution plate and relative closure cover, the distribution plate comprising a suction aperture, a discharge aperture and a feed aperture for the operating liquid. The distribution plate is of small thickness and is constructed from sheet steel. The relative suction aperture and discharge aperture can have sharp edges and be obtained by -punching or by plasma or laser cutting.

  • Publication number: 20020155004
    Abstract: A swash plate type compressor that has a pair of shoes between a swash plate and a piston. The motion of the swash plate is transmitted to the piston through the shoes. Each piston reciprocates according to the transmitted monitor. A coating is applied to each surface of the swash plate to contact the corresponding shoe. The surface of each coating is flat. Each shoe includes a substantially flat surface, which contacts the swash plate, and semi-spherical portion, which is fitted to the piston. Each substantially flat surface includes a main chamfered portion near the periphery. The inclination angle of each main chamfered portion will respect to the corresponding coating in a predetermined angle or less. Each coating contacts one of the substantially flat surfaces. The maximum distance between each main chamfered portion and the corresponding coating is equal to or less than the thickness of the corresponding coating.

  • Patent number: 5957666
    Abstract: A tandem-type pump assembly having a first housing and a second housing. A first main pump and a second main pump are coaxially aligned and disposed in the first housing. A first driving shaft having a first end and a second end is rotatably supported in the first housing and coaxially interconnects the first main pump and the second main pump. A driving gear is fixed to the first end of the first driving shaft for rotation therewith. A second driving shaft is rotatably supported in the second housing for driving an auxiliary pump. A driven gear is fixed to the second driving shaft for rotation therewith and directly engages the driving gear.

  • Patent number: 4362441
    Abstract: Method and apparatus are shown for control of continuous feeding of pulverized material to a high pressure container. A rotor is located within the high pressure container. The pulverized material is fed from a feed hopper through a stationary feed pipe to a vented spin-up zone chamber to a plurality of sprues mounted in the rotor. Control of the pressure within control nozzles downstream from the sprues adjusts the flow rate of coal through the sprues.

  • Patent number: 3963377
    Abstract: Disclosed is a pumping system using a pneumatically powered, submerged pump for lifting high viscosity oil from a well. The pump includes a flexible, bag-shaped expansible member or "bladder" mounted within a surrounding housing. Pressurized gas is supplied from the well surface to the bladder through a supply line. An inlet check valve permits oil in the formation to flow into the housing when the bladder is collapsed. When the bladder is expanded or displaced by the gas, the oil in the housing is displaced through an outlet check valve into a flow line which extends to the well surface. A submerged control valve channels gas into the bladder to control the bladder expansion. The control valve also functions to permit the gas in the bladder to flow into a vent tube to control bladder deflation.In a modified form of the invention, oil flowing into the housing expands the bladder and gas supplied to the housing collapses the bladder.
