Title:
CONTROL VALVE FOR VARIABLE DISPLACEMENT COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2007/094226
Kind Code:
A1
Abstract:
A control valve for a variable displacement compressor, where operation of a
valve section is not blocked by a foreign matter. In the control valve, one end
of a shaft (19) is not hidden in a guide hole (20) when the valve is closed but projected
from an opening end of the guide hole (20). When the valve is opened, the shaft (19)
operates in the direction where the one end of the shaft (19) projects from the
guide hole (20). As a result, even if there is a foreign matter (61) staying at the
opening end of the guide hole (20) when the valve is closed, the shaft (19) moves
in the direction to remove the foreign matter (61). Thus, the foreign matter (61)
is prevented or restricted from being pinched in a gap between the shaft (19) and
the guide hole (20), so that operation of the valve section is not blocked or restricted
by the foreign matter (61) from operating.
