摘要:
Relating to oil feed to a piston portion in a dual support bearing of a hermetic compressor, and a structure for improving efficiency and reliability and accomplishing reduction of noise is disclosed. In this structure, since an auxiliary bearing 119 is provided with an oil feed passage 129 for conducting lubricating oil 108 discharged from an upper end of an oil feed mechanism 114, to a sliding surface of a piston 120, the lubricating oil 108 is fed to the piston 120 and a piston pin 122 from the oil feed passage 129 to make the sealing performance excellent, so that the amount of leakage of refrigerant gas from a compression chamber 117 is reduced to improve the freezing capability or efficiency. Further, lubrication of sliding portions of the piston 120 and the piston pin 122 becomes excellent so that noise caused by sliding is reduced and the reliability is improved.

A refrigerant compressor includes a compressor section, driver, a first contact section and a second contact section. The compressor section is accommodated in a closed container for compressing refrigerant gas. The driver drives the compressor section. The first and second contact sections are brought into contact with each other or they slide with each other by driving the compressor section. On the surface of each one of the contact sections, at least one of plural recesses uniformly placed or a mixed layer, to which molybdenum disulfide (MoS2) is bound, is formed. The foregoing structure allows increasing the abrasion resistance of the first and second contact sections.

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:
A hermetically sealed compressor includes a sealed vessel filled with a coolant and a freezer oil, an electromotive element including a rotor and a stator and accommodated within the sealed vessel, and a compressing element accommodated within an upper region of the sealed vessel and adapted to be driven by the electromotive element. This compressing element is provided with a shaft, arranged so as to extend vertically and having the rotor mounted thereon, and a bearing for supporting the shaft. A first oil pump is provided in a lower portion of the shaft and opening into the freezer oil, a second oil pump is provided above the first oil pump and formed by a spiral groove, provided on an outer periphery of the shaft, and an inner peripheral wall surface of the rotor, and a third oil pump is provided above the second oil pump and formed by a spiral groove, provided on the outer periphery of the shaft, and an inner peripheral surface of the bearing.
摘要:
By adopting a construction in which a first balance weight is provided at the side end portion of the eccentric shaft portion of the auxiliary shaft portion and a second balance weight is provided at the side end portion of the eccentric shaft portion of the main shaft portion, it becomes possible to provide sufficient first balance weight and second balance weight, without spoiling the compact size of the compressor, thus enabling the reduction of noise and vibrations.

A linear actuator is provided with an outer tube and an inner tube inserted in the outer tube so as to be free to slide. The linear actuator is also provided with a rod erected at a central axis part of the inner tube and forming an annular space between the rod and the inner tube, a rod guide which slides along an inner surface of the outer tube and guides the rod along an axial direction, a plurality of permanent magnets arranged along the axial direction in the rod, and a plurality of coils retained by the outer tube so as to face the permanent magnets. A cooling fluid is filled in an internal space formed between the outer tube and the inner tube.

A tracking device includes feature information detection means for detecting feature information from a photographic image and tracking object matching means for comparing the feature information with tracking object information in which feature information of a plurality of figures are registered so that the feature information corresponds to a priority indicating tracking order of the feature information and for determining whether or not the feature information is information of the tracking object. The tracking device also includes priority acquisition means for acquiring the priority of the feature information detected from the tracking object information where it is determined that the feature information detected is the information of the tracking object and control means for controlling the photographing section, based on the priority acquired, so as to continuously include, in the photographic image from which the feature information is detected, feature information that has a highest priority in the photographic image.
