摘要： The sensitivity of a pressure-sensitive element in a pressure-sensitive part of a control valve for variable-capacity compressor is made adjustable by means of an adjusting screw provided so as to permit an adjustment of forward and backward movement with respect to a frame supporting the pressure-sensitive part. The adjusting screw is rotated by engaging an engagement part, which is annexed to a coil assembly constituting a solenoid excitation part, against the adjusting screw thereby to operate the coil assembly.

摘要： In a control valve for a variable capacity compressor, coolant that is sucked in from a suction chamber through a suction conduit is compressed and delivered to a delivery chamber through a delivery conduit and the coolant pressure is controlled by an electromagnetic control valve. Opening/closing control of a gas supply valve body (gas supply side) that communicates with the delivery conduit and a crank chamber and of an extraction valve body (extraction side) that communicates with the crank chamber and the suction conduit is performed in accordance with the suction coolant pressure of the suction conduit. A crank chamber communication port communicates with the extraction valve chamber.

摘要： The present invention provides a control valve which is capable of providing the quantification of the maximum flow rate on the occasion of opening the extraction valve and a predetermined small flow rate on the occasion of closing the extraction valve. This control valve comprises a main valve body provided with a discharge duct-communicating port, with a crank chamber-communicating port, with a crank chamber-communicating port, with an intake duct-communicating port, with a feed valve hole interposed between the discharge duct-communicating port and the crank chamber-communicating port, and with an extraction valve hole interposed between the inflow side crank chamber-communicating port and the intake duct-communicating port; a feed valve body which is capable of opening and closing the feed valve hole to a full or certain extent; an extraction valve body which is capable of opening and closing the extraction valve hole; and a solenoid magnetization portion which is capable of actuating the opening and closing of the feed valve body and of the extraction valve body. In a first status, a minimum flow rate is secured at the extraction valve body with the feed valve body being fully opened. In a second status, the feed valve body is fully closed and the extraction valve body is fully opened. In an intermediate status between the first status and the second status, the feed valve body is moved from a nearly closed state to a fully closed state depending on the value of control current. At the extraction valve body, a predetermined flow rate is effectuated irrespective of the opening degree thereof.
