Abstract
A sealed type electrically operated compressor including a sealed container, and a pair of scroll members in the sealed container each having an end plate and a spiral wrap located in upright position thereon. 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.
