摘要： When a rotary shaft of a scroll type compressor rotates and a movable scroll of the compressor makes an orbital movement around the axis of a rotary shaft by way of an eccentric shaft, refrigerant gas is supplied to compression chambers between a fixed scroll and the movable scroll. A first bearing rotatably supports the rotary shaft. A second bearing is provided between the movable scroll and the eccentric shaft to permit relative movement therebetween. A balance weight attached to the movable scroll dynamically balances the movable scroll during its rotation. A crank chamber accommodates the balance weight. A suction port is so provided in the housing as to communicate with the crank chamber, and permits the refrigerant gas to be supplied into the housing. A passage is formed in the balance weight, the eccentric shaft and the rotary shaft to supply the refrigerant gas into a first gap between the first bearing and the rotary shaft and a second gap between the second bearing and the movable scroll.

摘要： A scroll-type compressor has a fixed scroll member, a movable scroll member, a front housing, a rear housing and a gasket seal. The fixed scroll member and the movable scroll member cooperate to form a compression region. The movable scroll member orbits relative to the fixed scroll member to compress refrigerant in the compression region. A movable scroll base plate of the movable scroll member forms a rear surface and a discharge hole substantially at the center of the movable scroll base plate. Pressure of the refrigerant discharged from the compression region is applied to the rear surface of the movable scroll base plate. The front housing accommodates the movable scroll member. The rear housing which is adjacent to the front housing, has the fixed scroll member inside. The gasket seal is located between the front housing and the rear housing.
