  • Patent number: 9228538
    Abstract: An object of the invention is to provide an internal combustion engine control apparatus that can restrain an EGR amount from becoming excessive, and restrain destabilization of combustion . . . . First, in response to a change of an operation condition, operation amounts of a plurality of actuators that influence the EGR amount are set. When the operation amounts of the plurality of actuators are set, operation of an actuator that decreases the EGR amount (referring to an external EGR amount, an internal EGR amount or both, the same applying to the following) is started (S140), and thereafter, operation of another actuator that increases the EGR amount is started (S150).

  • Patent number: 9217398
    Abstract: In a gas engine 1 that uses a gas having a lower specific gravity than air and has a pre-mixing device before a turbocharger, a pre-mixed gas mixture compressed by a turbocharger 3 is cooled by an intercooler 4 located downstream of the turbocharger 3 in the intake system. Condensed water produced as the gas is cooled and the pre-mixed gas mixture discharged with the condensed water are separated into condensed water, air, and fuel gas in a vapor-liquid separator 7. The fuel gas is returned to the intake system upstream of the turbocharger 3, while the condensed water is discharged to atmosphere.

  • Patent number: 9206802
    Abstract: A rotatable drive shaft in the swash pump or turbine for liquids is supported by one bearing at each end. An integrated motor or dynamo uses the same two bearings. The compound first bearing supports a slanted section of the drive shaft placed inside the inner swash sphere, and transfers rotational power to the attached nutatable swash plate. The second bearing confines rotation of the drive shaft in a defined axis. Either one of the bearings is made to prevent axial movement of the drive shaft, preventing swash pump misalignment. A resilient drive, and an immersed pump are described.

  • Patent number: 9175681
    Abstract: A pump comprises a housing, with an interior defining a rotor path, an inlet formed in the housing at a first position on said rotor path, an outlet formed in the housing at a second position on said rotor path spaced from said first position. A rotor is rotatable in the housing with a first surface that seals against the housing. A second surface is formed on said rotor circumferentially spaced from said first surface and forms a chamber that travels around said rotor path to convey fluid from the inlet to the outlet. A resilient seal formed with the housing is located on the rotor path to prevent fluid flow from said outlet to said inlet past the seal. A passage may be provided to supply fluid to an under surface of the seal at a pressure that acts to urge the seal against the rotor.

  • Patent number: 9068457
    Abstract: The invention relates to a double-flow screw spindle machine for drive generation by multiphase mixtures or for the delivery of multiphase mixtures, comprising at least two separate inlet chambers (11, 12) and an outlet chamber (20), and a separator (30), situated upstream of the inlet chambers (11, 12), for separating liquid phase and gas phase. The object of the present invention is to provide a dual-flow screw spindle machine which is easily adaptable to changed process conditions. This object is achieved by virtue of the fact that both inlet chambers (11, 12) are connected to the separator (30) by separate lines (31, 32; 33) for the gas phase and the liquid phase.
