초록 ▼

A plurality of vane chambers on the back side of vanes are caused to function as pump chambers using the reciprocating movement of the vanes to pressure-feed a lubricating oil to a compressor mechanism unit. A taper hole at one of the vane chambers for drawing the lubricating oil, a hole on another chamber for mitigating back pressure and a taper hole between the chambers are provided to improve the pressure feeding capability. In addition, the lubricating oil having been supplied to the compressor mechanism unit is supplied to the slide surfaces of crank portions from an oil hole of each crank portion through an oil passage at the center of the rotating shaft and is further distributed optimally to slide bearing portions by oil guide grooves. A horizontal multiple cylinder rotary compressor is thereby provided, which employs an oil supplying structure capable of supplying lubricating oil stably and at an optimal distribution, which provides high reliability and high efficiency and by which vibration is reduced and space is saved.

대표청구항 ▼

A horizontal multi-cylinder rotary compressor, comprising: a compressor mechanism unit for compressing refrigerant and being within a sealed container; an electric motor unit for driving the compressor mechanism unit and being within the sealed container; a lubricating oil reservoir at a bottom portion of the sealed container for each of said compressor mechanism unit and said electric motor unit, said reservoirs being separate from each other; said compressor mechanism unit having a plurality of cylinders and a rotating shaft of the compressor mechanism unit supported generally horizontally by a bearing portion including a main bearing and sub-bearing; a first vane chamber formed in a sealed manner with respect to the reservoirs behind a first vane that reciprocates by following a roller which is eccentrically rotated within a first cylinder as said rotating shaft rotates; a second vane chamber formed in a sealed manner with respect to the reservoirs behind a second vane which similarly reciprocates within a second cylinder; a first communication passage provided in said first vane chamber and communicating lubricating oil directly with the lubricating oil reservoir of the electric motor unit at the bottom portion of the said sealed container; said second vane chamber being provided with an oil supply passage for supplying the lubricating oil to said bearing portion of the compressor mechanism unit, a hole for communication lubricating oil directly with the first vane chamber, and a second communication passage communication lubricating oil with the lubricating oil reservoir of the compressor mechanism unit at the bottom portion of the sealed container; and said first vane chamber being sealed except for said hole and said first communication passage.
