CONTROL VALVE, VARIABLE DISPLACEMENT TYPE COMPRESSOR AND REFRIGERATION CYCLE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide stability of pressure equalization action and good performance relating to response by making connection structures of each part of a valve element, a valve shaft and a plunger rod simple without requiring a large number of parts, simplifying a passage structure of a pressure equalization passage.

SOLUTION: A plunger 34 and a valve element 20 are connected by a plunger rod 35, and a main part of the pressure equalization passage is constructed by a communication hole 25 of the plunger rod 35.
