STARTING LOAD REDUCTION DEVICE FOR COMPRESSOR |
摘要 |
<p>PURPOSE:To minimize the compression load in the start time of a compressor by squeezing an intake passage for supplying refrigerant gas to a compression room. CONSTITUTION:A valve housing 8 having a spool valve 7 is installed on the way of an intake passage 27 for supplying a refrigerant gas from an evaporator to the compression room of a compressor. When the compressor is stopped, the spool valve 7 intecepts the intake passage 27 by the energized force of a spring 26. As an oil damper room 30 stays on one end of the spool valve 7 and an intake refrigerant gas pressure acts to the other end when the compressor is started, the spool valve 7 opens the intake passage 27 slowly. As an intermediate room 29 partitioned and formed in the center of the axial direction of the spool valve 7 and the position with comparatively low pressure of an intake room 3 are communicated with each other by a gas passage 34, the spool valve 7 is opened surely.</p> |
