  • Structure for controlling lubricant's flow rate in scroll compressor
    Patent number: 7736135
    Abstract: A scroll compressor including a block, a fixed scroll, an orbiting scroll, a crankshaft, an Oldham ring and an oil passage is provided, wherein the fixed scroll is fixed on the block, and the orbiting scroll, the crankshaft and the Oldham ring are disposed on the block. The fixed scroll and the orbiting scroll form a gas-in area, a compressing area and a gas-out area which are connected in a series. The orbiting scroll is eccentric connected with the crankshaft to orbit over the fixed scroll and drive the Oldham ring moving. A reciprocating motion area on the block is formed via the reciprocating motion between the block and the Oldham ring, wherein the block has an oil opening in the reciprocating motion area. Besides, one terminal of the oil passage is connected to the oil opening, and another terminal of the oil passage is connected to the gas-in area and the compressing area.
