| 1. A compressor comprising:
a cylindrical sealed container connected to an intake pipe and a discharge pipe;
a compression mechanism being disposed in the sealed container to compress gas introduced from the intake pipe and discharge
the gas into the sealed container, the compression mechanism including a compression chamber configured to compress gas introduced
from the intake pipe, a drive shaft movable about a rotation axis to operate the compression mechanism and an intake passage
extending in a radial direction relative to the rotation axis, the intake passage having one end that opens at the compression
chamber and an opposite end that opens in an outer lateral face of the compression mechanism to face a terminal end of the
intake pipe, both of the ends of the intake passage being at least partially aligned with the compression chamber and the
terminal end of the intake pipe as viewed in the radial direction along the intake passage;
a motor disposed in the sealed container and operatively connected to the drive shaft of the compression mechanism;
an elastic support member supporting the compression mechanism and the motor as an integrated unit within the sealed container
for movement together with respect to the sealed container; and
a sealing mechanism including a sealing member pressed against a sealed face formed by one of a peripheral part of the intake
passage in the outer lateral face of the compression mechanism and a part of an inner face of the sealed container which faces
the peripheral part to connect the intake pipe and the intake passage with each other by sealing a gap between the compression
mechanism and the sealed container,
the compression mechanism including an orbiting member that extends along the rotation axis to move between a pair of opposed
axially facing surfaces that define axial ends of the compression chamber such that both of the ends of the intake passage
are at least partially aligned with the orbiting member and the terminal end of the intake pipe as viewed in the radial direction
along the intake passage.
