摘要： A first lubricating oil passage and a second lubricating oil passage, extended from a contacting surface between a partition wall and a fixed scroll are formed in the partition wall (middle housing). A recess for communicating the first lubricating oil passage with the second lubricating oil passage is formed on the fixed scroll. Accordingly, the lubricating oil amount between the first lubricating oil passage and the second lubricating oil passage is easily controlled by adjusting the size of the recess.

摘要： Lubricant oil, separated from compressed fluid and stored in an oil storage chamber formed beneath a motor, is introduced via an internal oil supply passage to an attachment groove formed for installing a main bearing. The lubricant oil passes through the main bearing, and flows toward a compressor. The lubricant oil is also supplied to an oil supply hole formed inside a rotation shaft of the motor via lubricant oil grooves, and lubricates and cools a needle bearing. Accordingly, axial length of housing protruding portion is reduced, and thereby reducing an entire axial length of the electrically-driven compressor apparatus.

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.

摘要： Scroll compressors may preferably include, for example, a stationary scroll, a drive shaft member, a movable scroll, a bearing member, a compression chamber, a discharge port, a discharge valve and a discharge valve clamping device. The drive shaft member may revolve around a revolution axis. The bearing member may be disposed between the movable scroll and the drive shaft member in order to transmit the revolution of the drive shaft member to the movable scroll. The compression chamber may be defined by a space formed between the stationary scroll and the movable scroll. The compression chamber compresses the fluid drawn into the compression chamber when the movable scroll revolves or orbits with respect to the stationary scroll. The discharge port is disposed within the movable scroll and is adapted to discharge fluid within the compression chamber to the opposite side of the stationary scroll. The discharge valve clamping device is preferably affixed to the movable scroll. The discharge valve clamping device may prevent the discharge valve from moving together with the bearing member when the bearing member accidentally or unintentionally revolves together with the drive shaft member and independent from the movable scroll.

The inner surface of the accommodating space includes a bottom surface and a side surface. The bottom surface is defined as a radially inward surface of the inner surface relative to the central axis. The side surface surrounds a periphery of the bottom surface. The bottom and side surfaces are defined by the compressor housing. The motor drive circuit is arranged in the accommodating space for driving the electric motor.

摘要： An oil storage area (45a) is defined on the bottom of a motor chamber (45) of a scroll compressor (1). An oil transfer route (4a) is defined in the portion of a center housing (4) that corresponds to the storage area (45a). Lubricating oil L is separated from the discharged, compressed refrigerant by an oil separator (80) and the lubricating oil L is supplied to the backside of a movable scroll (20) due to a pressure differential within the compress (1). After lubricating a bearing (10), the lubricating oil L is temporarily stored in the storage area (45a) and then is transferred due to a pressure differential to the suction-side of a compression mechanism (21) via the oil transfer route (4a). The lubricating oil L is then transferred to the oil separator (80) together with the compressed refrigerant that is discharged from a compression chamber (32) of the compression mechanism (21). Thus, the lubricating oil L contained in the discharged, compressed refrigerant can be effectively separated from the compressed refrigerant and circulated to and from the back side of the movable scroll (20) in order to lubricate moving parts within the compressor (1) using the pressure differentials within the compressor (1).
