    摘要： A gear pump is used in an electrically-operated sealed compressor. The compressor includes a compression mechanism, an electric motor for driving the compression mechanism, and a crankshaft for transmitting the rotational force of the electric motor to the compression mechanism. The gear pump includes a pair of gears being in mesh with each other, one of which is connected to one end of the crankshaft, and a pump casing accommodating only the pair of gears. The pump casing together with the gear pair is disposed on one side of a cover plate, while other elements constituting the gear pump are disposed on the other side of the cover plate. By this construction, the distance between the gear pair and an auxiliary bearing to which the gear pump is secured can be reduced and, hence, an undesirable whirling of one end portion of the crankshaft can also be reduced.

    摘要： A hermetic electric scroll compressor includes a fixed scroll and an orbiting scroll which define therebetween a plurality of compression spaces for compressing fluid introduced via a suction port. The orbiting scroll has a base plate and a shaft portion extending from the base plate toward a crankshaft rotatably supported by a support member. A seal member is disposed between the base plate and the support member to define an inner region and an outer region. The shaft portion is exposed to the inner region, while the outer region communicates with the suction port. The shaft portion is formed with an axial hole open to the inner region, while the base plate is formed with a radial hole open to the outer region. Communication is established between the axial and radial holes via a small-diameter hole so that lubricating oil supplied to the inner region is introduced into the outer region via the small-diameter hole for feeding to the compression spaces via the suction port.
