    • A valve for controlling the flow of a drilling fluid through a downhole tool positionable in a wellbore penetrating a subterranean formation. The downhole tool has a housing with a drilling motor therein and a drill bit at an end thereof. The drilling motor has a housing with a rotor rotationally movable in a rotor channel as the drilling fluid passes through a rotor channel between the housing and the rotor. The rotor has a bypass channel therethrough for bypassing a portion of the drilling fluid therethrough. The valve includes a valve plate positionable upstream of the motor. The valve plate has at least one flow passage and at least one bypass passage therethrough. The flow passage is in fluid communication with the rotor channel for passing the drilling fluid therethrough. The bypass passage is in selective fluid communication with the bypass channel when the rotor rotates about the housing and moves the bypass channel into alignment with at least a portion of the bypass passage for bypassing a portion of the drilling fluid therethrough whereby a hammering effect is generated on the bit.

    • A compressor is provided having an accumulator that forms an accumulating chamber in an internal space of a shell of the compressor, reducing a size of the compressor and simplifying an assembly process. A stationary shaft having a refrigerant suction passage may be directly connected to the accumulator to prevent leakage of refrigerant. Further, a center of gravity of the accumulator may correspond to a center of gravity of the compressor to reduce vibration and noise of the compressor caused by the accumulator. Furthermore, an eccentric portion may be provided at the stationary shaft to secure a spacious compression space. Both ends of the stationary shaft may be supported by a frame to reduce vibration. Also, a rotor and a cylinder may be coupled with a bearing in an integrated manner to reduce cylinder deformation. An installation area of the compressor including the accumulator may be minimized to enhance design flexibility of an outdoor device employing the compressor and minimize interference with other components, thereby facilitating installation of the outdoor device.
    • 提供了一种压缩机,其具有在压缩机壳体的内部空间中形成蓄积室的蓄能器,减小了压缩机的尺寸并简化了组装过程。 具有制冷剂吸入通道的固定轴可以直接连接到蓄能器以防止制冷剂泄漏。 此外,蓄能器的重心可以对应于压缩机的重心,以减少由蓄能器引起的压缩机的振动和噪声。 此外,可以在固定轴处设置偏心部分,以确保宽敞的压缩空间。 固定轴的两端可以由框架支撑以减少振动。 此外,转子和气缸可以与轴承以一体的方式联接以减少气缸的变形。 可以将包括蓄能器的压缩机的安装区域最小化,以提高使用压缩机的室外装置的设计灵活性,并最小化与其他部件的干扰,从而便于室外装置的安装。

    • The present invention relates to an electrically driven scroll compressor. The electrically driven scroll compressor includes a housing into and from which a refrigerant is introduced and discharged, a driving part disposed within the housing to generate a rotation force of a driving shaft, an orbiting scroll rotated by the driving part, a scroll compression part including a fixed scroll to compress the refrigerant, wherein the fixed scroll and the orbiting scroll define a compression space therebetween, and a sliding bush disposed between the driving shaft and the orbiting scroll to eccentrically rotate with respect to the rotation of the driving shaft, the sliding bush transmitting the rotation force of the driving shaft to the orbiting scroll. An oil flow passage, through which oil flows, is defined in the housing for lubrication. Also, an inclined portion is disposed on an end in a rotation direction of the sliding bush. The inclined portion is disposed on the oil flow passage. Since a portion of the flowing oil or the entirety of the oil compresses the inclined portion, a moment is applied in a direction opposite that of a moment resulting from the eccentricity of the sliding bush. Thus, according to the present invention, tilting can be reduced to prevent the partial abrasion of the sliding bush and of a sliding bearing, thereby improving the lifespan of the compressor. In addition, the electrically driven scroll compressor can be stably operated, and resistance against oil can be reduced to reduce power consumption.
    • 本发明涉及一种电动涡旋压缩机。 电动涡旋压缩机包括:制冷剂被引入和排出的壳体;设置在壳体内以产生驱动轴的旋转力,由驱动部旋转的绕动涡旋的驱动部,包括 用于压缩制冷剂的固定涡旋盘,其中固定涡旋件和绕动涡盘在其间形成压缩空间,以及设置在驱动轴和绕动涡旋件之间的滑动衬套,以相对于驱动轴的旋转偏心旋转, 衬套将驱动轴的旋转力传递到绕动涡旋件。 在壳体中限定油流动的油流通道用于润滑。 此外,倾斜部分设置在滑动衬套的旋转方向的端部上。 倾斜部设置在油流路上。 由于流动的油的一部分或油的整体压缩倾斜部分,所以与由滑动衬套的偏心导致的力矩相反的方向施加力矩。 因此,根据本发明,可以减少倾斜以防止滑动衬套和滑动轴承的部分磨损,从而提高压缩机的寿命。 此外,电动涡旋压缩机可以稳定地操作,并且可以降低耐油性,从而降低功耗。
