摘要： A lubricating oil supply structure of a vane-type compressor wherein shapes and positions of first and second recessed portions 36, 37 formed on blocks 5, 6 are adjusted such that, with a lubricating oil supply passage where lubricating oil enters a back pressure chamber 10 from an oil reservoir chamber 19 through a first recessed portion 36 and, thereafter, reaches a second bearing 12 from the back pressure chamber 10 through a second recessed portion 37.
The first recessed portion 36 and the back pressure chamber 10 are communicated with each other so that lubricating oil is supplied to the back pressure chamber 10 from the oil reservoir chamber 19 during a period where a stroke amount of a vane 9 is increased so that pressure in the back pressure chamber 10 is relatively lowered.
The second recessed portion 36 and the back pressure chamber 10 are communicated with each other so that lubricating oil in the back pressure chamber 10 is delivered and is supplied to the second bearing 12 during a period where the stroke amount of the vane 9 is decreased so that pressure in the back pressure chamber 10 is relatively increased.

摘要： To provide a piston compressor capable of preventing excessive oil from accumulating in a crank chamber in any operation state while securing the supply of oil to a swash plate. In a piston compressor in which an oil separation passage (43) is formed in a shaft (7) and a crank chamber (2) communicates with a suction chamber (31) through the oil separation passage (43), a supply passage (40) opens at a region of a cylinder block (1) opposed to a swash plate (18) to thereby allow a working fluid introduced from a discharge chamber (32) into the crank chamber (2) to be supplied to the swash plate (18) and a bypass passage (50) allowing the crank chamber (2) to constantly communicate with the suction chamber (31) is provided to thereby prevent the accumulation of excessive oil in the crank chamber (2) regardless of the operation condition. The bypass passage (50) communicates with the crank chamber (2) at a region positioned in the outer side of a rotation trajectory of the swash plate (18) in the radial direction.

摘要： To reduce a size of an oil separator by improving oil separation performance of the oil separator of a compressor in the compressor having a centrifugal separation type oil separator. To further improve the oil separation performance by forming a processing drill so as not to interfere with a separation pipe at the time of drilling a refrigerant introduction path and by connecting the refrigerant introduction path to an inner peripheral surface of a separation chamber smoothly even when the oil separator is reduced in size. To further secure a clearance at a portion where an opening of the refrigerant introduction path faces. In a compressor having an oil separator 14 including a separation chamber 22, a separation pipe 23 housed in the separation chamber 22 and a refrigerant introduction path 21 allowing a discharge chamber 11 to communicate with the separation chamber 22, an axial center 0 of the separation chamber 22 and an axial center 0' of the separation pipe are shifted from each other.

摘要： To provide a vane type compressor that can appropriately keep the allocation of the clearances at the front and rear ends in the axial direction of the rotor by balancing the forces applied to the front and rear sides of the drive shaft. The clearances at the front and rear ends in the axial direction of a rotor 3 are appropriately allocated by providing, in a drive shaft 2, a passage 52 communicating between a low-pressure space 26 communicating with a suction chamber 29 and a shaft end space 15 partitioned by a rear side block 13 and the end of the drive shaft 2 and balancing the forces applied to the front and rear sides of the drive shaft 2. This prevents the compression efficiency from reducing while ensuring the smooth rotation of the rotor 3.
