摘要： In a scroll compressor, the side of the orbiting end plate away from the compression chambers is slidably supported by an annular protusion formed in the frame. A lower pressure chamber is formed on the radially outer side of this annular protrusion, and an Oldham's ring is fitted inside the lower pressure chamber.

摘要： In a scroll compressor, at least one suction port for gas is opened in a stationary end plate which has a spiral wrap. Gas is drawn directly into the compression chambers from the suction port. In addition, the suction port has an opening straddling both the radially extending surface of the stationary end plate at the outermost circumference of the compression chambers and the compression chamber side wall that is perpendicular to the radially extending surface, and the opening area of the suction port is relatively large.

摘要： A scroll compressor has a channel formed in a compressor member such as main shaft, frame, orbital scroll member, through which lubricating oil can pass easily from the higher pressure side to the lower pressure side under flow control between sliding surfaces of the compressor members without reduction in the sealing between the higher pressure side and the lower pressure side, whereby injecting sufficient lubricating oil between the scroll members improves both the sealing and the lubricating between the scroll members.

摘要： In a scroll compressor for compressing gas a scroll unit having stationary and orbiting scroll members with interfitting spiroidal wraps is hermetically enclosed in a housing. During operation, a compression chamber defined between the scroll chambers is given a high pressure, and the space in the housing below the orbiting scroll member is given a low pressure atmosphere. A motor housed in the low pressure atmosphere rotates a drive shaft. This drive shaft causes the orbiting scroll member to orbit. A passage is provided in the orbiting scroll member to connect the low pressure atmosphere and the compression chamber. A thrust reduction mechanism is supported by the housing in the low pressure atomophere. The thrust reduction mechanism receives the pressure of the compression chamber via the passage.
