摘要： A hermetic compressor includes a hermetic container, a compression element accommodated in the hermetic container, and a motor element driving the compression element. The hermetic container has an inner space therein arranged to store lubrication oil. The compression element includes a shaft unit rotating about a rotation axis. The shaft unit has an oil-feeding passage provided therein. The oil-feeding passage extends upward from a lower end of the shaft unit. The shaft unit has an oil-spattering hole provided therein. The oil-spattering hole extends substantially perpendicularly to the rotation axis. The oil-spattering hole has a first open end communicating with the oil-feeding passage and a second open end opening in the inner space of the hermetic container. The second open end has a cross-sectional area smaller than a cross-sectional area of the first open end. This hermetic compressor supplies lubrication oil to sliding component, such as a piston, of the compression element, thus operating reliably and efficiently.

摘要： A hermetic compressor has a bipolar permanent magnet motor where permanent magnet (124) is disposed in rotor core (123). Hollow bore (131) is disposed at the end on the compressing element (105) side of rotor core (123), and main bearing (111) extends into bore (131). The thickness of rotor core (123) is longer than that of stator core (126), thereby widening the magnetic path of rotor core (123). The magnetic flux amount generated in rotor core (123), which is conventionally insufficient due to existence of bore (131), increases, the loss decreases, and the efficiency increases.

摘要： A highly reliable reciprocating compressor works efficiently with less energy, and produces smaller vibrations. This reciprocating compressor includes a crankshaft, a block, a piston, a connecting rod, and a balancing weight. The cylinder is placed offset such that an axis line thereof and an axis line of the main shaft do not cross each other. The center of gravity of the balancing weight is placed substantially opposite to the center of the eccentric section with respect to the axis line of the main shaft and deviated along a rotating direction of the main shaft from the place just opposite to the center of the eccentric section. The foregoing construction allows reducing lateral pressure of the piston, thereby increasing the reliability and efficiency of the reciprocating compressor, and allows to cancel unbalancing force produced by motions of the piston, the connecting rod and the eccentric section with motion of the balancing weight.

摘要： The present invention relates to a hermetic compressor that stores oil (106), and houses compression mechanism (105) that compresses a refrigerant gas, in housing (101). Piston (140) is formed with at least two grooves (144) that do not include the edges of top surface (142) and skirt surface (143), on outer circumferential surface (145) of the piston, where groove (144) communicates with the space in housing (101), at least near the bottom dead center. Such a makeup allows the sliding part to be supplied with oil through groove (144), increasing efficiency owing to high sealability and a low sliding loss.
