Title: Variable displacement compressor having displacement control valve
Inventor: TAGUCHI YUKIHIKO
IPC: F04B27/14
Filed: 2003-04-18
Abstract: <P>PROBLEM TO BE SOLVED: To provide a variable displacement compressor for improving a leading characteristic at the start by rapidly relieving a refrigerant in a crank chamber in an intake chamber.  <P>SOLUTION: When the electromagnetic force of a displacement control valve 20 exceeds a predetermined value, a valve part 24b closes communication passages 66 and 68, and communication of a crank chamber with a discharge chamber is blocked. Since a refrigerant in the discharge chamber is not introduced in the crank chamber, a flow of the refrigerant from the crank chamber to the intake chamber via a variable orifice mechanism is generated. Since a large diameter part of a stepped part (a truncated conical part) integrated with an upper side of the valve part is detached from a hole in a partition 25, a space between the stepped part and the hole in the partition is increased. The variable orifice mechanism has the diameter necessary and sufficient for allowing a blow-by gas generated when compressing the refrigerant by a piston to flow in the intake chamber, and the pressure in the crank chamber is rapidly dropped, and equal to the pressure in the intake chamber. Therefore, the displacement of the compressor is maintained at a maximum value.  <P>COPYRIGHT: (C)2004,JPO
