    Abstract: A regulatable coolant pump and a method for regulation of this regulatable coolant pump for internal combustion engines, which is driven by way of a pulley actives a valve slide using an electromagnetically activated piston pump equipped with a return spring in the form of a pressure spring. The pump implements a “pump feed” using many small “partial lifts.” A “leakage volume stream” that flows opposite to the “pumped volume stream” is superimposed on the “pumped volume stream” via the arrangement of circular apertures both in the inlet valve membrane of the working piston and in the outlet valve membrane so that the valve slide can be moved in defined manner and in a very robust and reliable manner, with low drive power via the defined superimposition of these two volume streams.

  • Publication number: 20130094942
    Abstract: Non-uniform variable stator vanes for a single stage of a gas turbine engine stage include non-uniform airfoils with a non-uniformity between airfoils of first and second portions of the stator vanes. The variable stator vanes may further include all outer buttons, from which the airfoils inwardly extend, in all of the variable stator vanes being equally sized and shaped and the same all inner buttons if used. The airfoils in the first and second portions may be counter-clockwise and clockwise biased respectively with respect to a nominal airfoil position. The airfoils in the first and second portions may be counter-clockwise and clockwise leaned respectively with respect to the nominal airfoil position. Outer ends of the airfoils in the first and second portions may be counter-clockwise and clockwise shifted respectively with respect to the nominal airfoil position.

  • Publication number: 20130058757
    Abstract: A priming valve for priming a centrifugal pump includes a valve assembly separating an inlet chamber from an outlet chamber. The inlet chamber is fluidly coupled to an intake for the centrifugal pump and the outlet chamber is fluidly coupled to a priming pump. A control valve is provided to operate the valve assembly in order to fluidly connect the inlet chamber with the outlet chamber. While the valve assembly fluidly connects the inlet chamber with the outlet chamber, the priming pump can operate to replace air in the intake and the centrifugal pump with water.

  • Publication number: 20130058763
    Abstract: A device for adjusting variable guide vanes of an axial-flow machine includes a control rod that adjusts an angular position of the variable guide vanes and is pivotably connected to a shaft. Each of a first and a second bracket has a first end connectable to a casing of the machine. A first joint is fixed to a second end of the first bracket and provides adjustable positioning of a first end of the shaft. A second joint is fixed to a second end of the second bracket and provides adjustable positioning of a second end of the shaft. The two joints are spatially positioned to each other solely via a first fixed connection between the first end of the first bracket to the casing and via a second fixed connection between the first end of the second bracket to the casing.

  • Publication number: 20130048091
    Abstract: An exemplary valve device for controlling flow of a turbomachine fluid includes a housing and a flow control assembly within the housing. The housing has a first inlet, a second inlet, and an outlet. Movement of the housing to a first orientation causes the flow control assembly to move to a first position to restrict flow of a turbomachine fluid into the housing through the second inlet. Movement of the housing to a second orientation causes the flow control assembly to move to a second position to restrict flow of the turbomachine fluid into the housing through the first inlet.

  • Publication number: 20130051977
    Abstract: A pump having an insert between an impeller and diffuser, where the insert includes an annulus that is in communication with fluid flow passages in the impeller and diffuser. The passages and annulus define a fluid flow path through the pump. Vanes are provided in the annulus that can pivot and vary the cross sectional area of the fluid flow path. Regulating the fluid flow path area alters the flow rate where the pump operates at its maximum efficiency. Thus by monitoring flow through the pump, the vanes can be adjusted so the flow rate of maximum efficiency corresponds to the actual flow rate.

  • Publication number: 20130051988
    Abstract: A turbocharger (1) with variable turbine geometry (VTG), having a blade bearing ring (6), which has a multiplicity of guide blades (7), and which has a stop (25) at least for adjusting the minimum throughflow through the nozzle cross sections formed by the guide blades (7), wherein the stop (25) has a fixing peg (32) on which a deformable, arched adjusting section (26) is arranged. Since the stop is formed as a deformable component which can be fixed in the guide grate, it is possible after the assembly of the guide grate to rework said stop in a simple manner in order to precisely set the required stop position, since said stop is not integrally connected to the guide grate.

  • Publication number: 20130045087
    Abstract: There is described an airfoil combination for aircraft turbofan, designed to save fuel in aircraft operation, which is composed by two wings (5) and two supports (6) articulated or not, for each of the wings (5). These two wings (5) are located inside the turbofan, internally to the outer fairing (3) of the turbofan and externally to the other components of the turbofan. In one of the embodiments, the two wings may have high-lifting devices, such as flaps. The two wings use the “blown” air at great speed by the fan (1) to generate a pre-determined lifting effect pursuant to the flight phases and the operating regimes of the turbofans to compensate totally or partially the weight of the turbofan itself, reducing the lift effort to be generated by the aircraft wings.
