Abstract
A hermetic compressor includes a casing, a cylinder in the casing, a first bearing and a second bearing defining a compression space together with the cylinder, a roller located at an eccentric position with respect to an inner surface of the cylinder and configured to vary a volume of the compression space, and a vane inserted into the roller to rotate together with the roller, and drawn out toward the inner surface of the cylinder to divide the compression space into compression chambers. An inlet port in communication with the compression space is defined in the first bearing, and an intermediate plate is located between the cylinder and the inlet port and defines a suction passage connected to the inlet port, where a peripheral length of an inner peripheral surface of the suction passage is greater than a peripheral length of an outer peripheral surface of the suction passage.
