<p><P>PROBLEM TO BE SOLVED: To restrain resonant phenomena in which a valve element jumps up from a valve seat in the vicinity of full close of a capacity control valve for controlling the duty ratio in a variable displacement compressor. <P>SOLUTION: In the valve 1, the passage between a port 5 for letting in refrigerant of discharge passage Pd and a port 6 for letting out the refrigerant of controlled presence Pc into a crankcase is controlled to be opened/closed. A lateral load is applied to the valve element 8 of the valve 1 by a leaf spring of a resonance-restraint member 11. The valve element 8 driven by a solenoid receiving pulse current is restrained from jumping, which is caused in the vicinity of the valve seat 7 by collision with the valve seat 7, by sliding resistance of the valve element 8 to the leaf spring. Since the resonance phenomena of the valve element 8 are restrained, rising in the suction pressure Ps is characteristically suppressed and the durability can be improved. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
