Abstract

PURPOSE: To provide a small-sized compressor which is suitable for high speed operation or low speed operation by means of inverter driving by setting times at 2 - 2.5 and installing a check valve mechanism at a discharge port to make a back pressure opening a rationalized mechanism.
CONSTITUTION: Lap times of a fixed scroll member 5 and a swivel scroll member 6 are set at approximately 2 - 2.5, the fixed scroll member 5 is provided with a check valve mechanism 4 on the upper part of a discharge port 10 in the center part of an end plate 5a so that the motor part may be variable speed-operated with an inverter 30. Besides, in the end plate of the swivel scroll member 6, a back pressure opening which communicates a compression chamber with a back pressure chamber 20 installed on the rear surface of the end plate is opened inwardly from the end edge part of the lap by one turn, and the innermost chamber in the lap center part formed out of both scroll members 5, 6 and the back pressure opening are so constituted as to have such a positional relation as their communication may be interrupted all the time.
