摘要： 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.
