摘要： A two-cylinder type rotary compressor has two compression elements each provided with a cylinder. First and second intake conduits are respectively formed in the cylinders so as to be in parallel to an intermediate partition plate disposed between the cylinders. Each one end of first and second intake tubes is connected to each of the intake conduits and each other end of the intake tubes is connected to a common intake pipe which is provided outside a hermetic casing.

摘要： The vane slot 20 and lubricating oil passageway 21 in the cylinder member 3 of a rotary vane compressor are configured such that the radial length of the slot wall 20a on the low pressure side of the vane 5 is less than that of the opposite wall 20b on the high pressure side. Such a shortened low pressure side slot wall reduces wear by providing improved lubrication at the critical inward edge of the slot (F1), and facilitates the flushing away of abrasive particles formed during the initial seating of the vane. For a horizontal installation the lubricating oil level is maintained below the radially outermost edge of the wall 20a to prevent the oil from being drawn into the low pressure chamber 17 when the compressor is stopped.

摘要： An oil hole is formed in a thrust-bearing surface in the eccentric part of a rotary shaft so that a given amount of lubricating oil is always maintained in the oil hole, whereby shortage of oil does not occur at the time of restarting of the rotary compressor after a long term pause of the operation.

摘要： An eccentric part of a crank shaft rotated in a cylinder is made a large diameter and a thin-walled rolling piston is fitted to the outer circumference of the eccentric part so that an injection opening for supplying a refrigerant into the cylinder is covered in a certain section by only a side surface of the eccentric part or both the side surfaces of the rolling piston and the eccentric part.

摘要： An eccentric part of a crank shaft rotated in a cylinder is made large in diameter and a thin-walled rolling piston is fitted to the outer circumference of the eccentric part so that an injection opening for supplying a refrigerant into the cylinder, the opening being formed in a bearing plate, is covered by only a side surface of the rolling piston or both the side surfaces of the rolling piston and the eccentric part.
