<p>PROBLEM TO BE SOLVED: To provide a control valve having an operational property not susceptible to be affected by pressure of a pressurized regions upstream and downstream control passage, and to permit a cross section of a solenoid rod and an opening area of a solenoid rod guide hole to lower an accuracy. SOLUTION: A discharge chamber is communicated with a crank chamber for housing a swash plate by control passages 48. A control valve 49 is interposed in the control passages 48, and controls opening degrees of the control passages 48 to change an inclination angle of the swash plate, resulting in controlling delivery capacity. A valve chamber 73 of the control valve 49 is communicated to the control passage 48 through a valve hole 75. A valve element 74 is accommodated in the valve chamber 73 to open and close the valve hole 75. Bellows 87 is operationally connected to at one side of the valve body 74 through a pressure sensitive rod 89. A solenoid portion 72 is operationally connected to the other side of the valve element 74 through a solenoid rod 96. The valve hole 75 is communicated to the discharge chamber. The valve chamber 73 and the solenoid portion 72 are adjacent to each other, and the valve chamber 73 and a plunger chamber 91 of the solenoid portion 72 are communicated to the crank chamber.</p> |
