Semi- encapsulated type refrigerant compressor

摘要

PURPOSE: To provide the mounting structure of a temperature sensor provided at a compressor for an injection control to be simply mounted with a high temperature sensitivity in a semihermetic refrigerant compressor to be cooled by liquid injection. ;CONSTITUTION: The casing of a compressor 1 has a terminal box 10 which is partitioned to a first terminal chamber 24 and a second terminal chamber 26. A temperature sensor 20 is so mounted in the chamber 26 by pressing its temperature sensitive surface to a terminal block 28 by a clamping fitting 35. Since the sensor faithfully detects the temperature of the compressor 1, the solenoid valve of a liquid injection circuit is switched in response to the temperature to be accurately controlled, thereby providing the compressor having high operating efficiency.;COPYRIGHT: (C)1995,JPO
