The orbiting and the stationary scroll members are assembled with the respective wraps facing inwardly and meshing with each other, and the orbiting scroll member is rotated by an electric motor to move in orbiting movement to compress fluid in compression spaces defined by the two scroll members and discharge compressed fluid into a space in the container. A suction pipe defining a suction passage for the fluid to be led therethrough into the compression spaces extends at one end portion through the end plate of the stationary scroll member to open in a suction space defined by the two scroll members and extends at the other end portion through a wall of the sealed container axially to communicate with external equipment on the lower pressure side. The suction pipe is securely connected at one of two opposite end portions and non-securely connected at the other end portion to the end plate of the stationary scroll member and to the wall of the cylindrical sealed container. A gas sealing member is disposed at the end portion of the suction pipe that is non-securely connected.

摘要： A scroll compressor is disclosed. A first main bearing and a second main bearing is coaxially formed on the sole frame but a balancer can be easily attached to a drive shaft by forming a space and an opening in the frame of the scroll compressor. The balancer is inserted through the opening formed in the periphery of the frame. One end of the drive shaft is inserted in the hole of the balancer and the first and second main bearings. The drive shaft and the balancer are fixed by suitable fixing means, so that the drive shaft is rotatably supported by the first and second main bearings, and the balancer can be rotated together with the drive shaft. Accordingly, since the frame of this invention has a single, integral frame structure, it is possible to coaxially form the first main bearing and the second main bearing, both of which are mounted on the frame.

摘要： A scroll compressor has a scroll mechanism disposed in a closed container and driven by a motor through a crank shaft rotatably supported at two points by first and second bearings disposed adjacent the opposite ends of the motor. The bearing which is remote from the scroll mechanism comprises a sliding bearing. The first end of the crank shaft remote from the scroll mechanism has a peripheral surface disposed in sliding engagement with the sliding bearing and formed therein with a lubricant supply groove communicated with an axial lubricant supply hole formed in the crank shaft and having a closed end adjacent the first end of the crank shaft and opened in an end face of a crank pin section thereof. The sliding bearing is communicated with a lubricant reservoir formed by a lower part of the container. The lubricant in the reservoir is subjected to the pressure of a compressed fluid discharged from the scroll mechanism and is forcibly fed into the lubricant supply groove through the sliding bearing.

摘要： A compressor unit composed of a fixed scroll and an orbiting scroll which are engaged with each other, and a variable speed motor are disposed in a hermetic chamber. A first bearing is provided in an engagement portion between a crankshaft and the orbiting scroll in an intermediate pressure chamber provided on a back surface of the orbiting scroll for applying thereto an intermediate pressure between a discharge pressure and a suction pressure. The crankshaft is supported by a second bearing provided close to the orbiting scroll and a third bearing provided close to the motor. The first, second and third bearings are lubricated by force of a differential pressure between the discharge pressure and the intermediate pressure through an oil passage. The oil passage is in communication at one end thereof with the lubricant oil on which the discharge pressure is applied, and opens at the other end thereof into the intermediate pressure chamber. Thus, a wear and a sticking of the bearings are prevented even in a low speed region and a high speed region where it is impossible to supply oil with a conventional centrifugal pump.
