  • Patent number: 9835155
    Abstract: A gear pump apparatus includes a gear pump and a sealing mechanism which includes an annular rubber member, an outer member, and an inner member. One of the outer member and a casing of the gear pump apparatus has a contact member located outside a portion of the outer member which contacts the gear pump in a radial direction of the gear pump. The contact member is placed to create a physical contact between the outer member and the casing to absorb a part of force by which the outer member is pressed against the gear pump. This results in a decrease in pressure acting on an area of contact between the outer member and the gear pump, which leads to a drop in resistance to sliding between the gear pump and the outer member, thus decreasing a loss of torque required for the pumping operation of the gear pump.

  • Patent number: 9816505
    Abstract: A scroll compressor is provided that may prevent an oil-feeding hole from being blocked due to a high pressure refrigerant, which is compressed in compression chambers and introduced into the oil-feeding hole through an oil-feeding slit, by blocking one of both end portions of the oil-feeding slit, adjacent to the compression chambers, when the oil-feeding hole is formed through an outer circumferential surface of a bearing and the oil-feeding slit, which communicates with the oil-feeding hole, is formed on the outer circumferential surface. This may allow for smooth oil supply onto the outer circumferential surface of the bearing through the oil-feeding hole, thereby enhancing a bearing performance. Also, the oil-feeding hole or slit may be formed at a closest position to an oil feeding-required section, not within the section. This may allow for quick oil supply into the oil feeding-required section, resulting in further enhanced bearing performance.

    Abstract: A turbocharger includes a variable turbine nozzle formed between first and second walls. A variable-vane assembly has a fixed nozzle ring and a plurality of circumferentially spaced vanes disposed in the nozzle and rotatably mounted on the nozzle ring such that the vanes are pivotable. The nozzle ring defines the first wall of the turbine nozzle, each vane having a first end adjacent the first wall and a second end adjacent the second wall. The second wall of the turbine nozzle is formed by a gas pressure-responsive member that is arranged to be axially movable relative to the vanes. A first stop is positioned so that the gas pressure-responsive member is urged against the first stop by a differential gas pressure exerted on the gas pressure-responsive member so that there is a non-zero first value for a clearance between the second ends of the vanes and the second wall of the turbine nozzle.

  • Patent number: 9765784
    Abstract: An Oldham coupling structure for a scroll compressor decreases Oldham coupling pressure loading without increasing compressor diameter or significantly increasing orbiting scroll or Oldham coupling inertia. The Oldham coupling key height and area are increased by recessing the key face into the ring portion of the Oldham coupling, increasing the key height and adding pads to the involute side of the orbiting scroll base plate to extend the key slot, potentially resulting in reduced compressor diameter and/or reduced orbiting scroll and Oldham coupling inertia.
