Embodiment 1

[0049] refer to Figure 1 to Figure 3 , the capacity control valve according to Embodiment 1 of the present invention will be described. exist figure 1 Among them, 1 is the capacity control valve. The capacity control valve 1 is mainly composed of a valve main body 2 , a valve body 21 , a pressure sensitive body 22 and a solenoid unit 30 . Hereinafter, the respective configurations constituting the capacity control valve 1 will be described.

[0050] The valve main body 2 is composed of a first valve main body 2A having a functioning through-hole therein, and a second valve main body 2B integrally fitted to one end portion of the first valve main body 2A. Furthermore, the first valve body 2A is made of metal such as brass, iron, aluminum, or stainless steel, or a synthetic resin material. On the other hand, since the second valve main body 2B functions as a magnetic circuit of the solenoid unit 30 , it is made of a magnetic material such as iron with low magnetic resistan...

Embodiment 2

[0079] refer to Figure 4 to Figure 6 A capacity control valve according to Embodiment 2 of the present invention will be described. The capacity control valve 50 according to the second embodiment is mainly different from the embodiment in that the first valve portion surface 21H formed at the boundary portion between the valve body first end portion 21E and the first valve portion 21G of the valve body 21 is formed of a tapered surface. Example 1 is different, but other basic configurations are the same as in Example 1, and the same symbols are assigned to the same components, and repeated descriptions are omitted.

[0080] Figure 4 It is a front sectional view showing the capacity control valve according to the second embodiment of the present invention. Figure 5 express Figure 4 The enlarged view of part B and the action state of the valve body 21.

[0081]The valve body 21 is a hollow cylindrical member, has an intermediate communication passage 26 inside the valve...

Abstract

To provide a capacity control valve having an improved function of discharging a liquid refrigerant in a control chamber when a variable capacity compressor is started, the capacity control valve making it possible to shorten the start time of the variable capacity compressor and, at the same time, to increase responsiveness of capacity control at the time of control. A capacity control valve comprising: a valve main body 2 having a first valve chamber 7 that channels a control pressure fluid and has a first valve seat surface 31A, and an internal space 4 that channels an intake pressure fluid; and a valve body 21 having an intermediate communication passage 26 that communicates the first valve chamber 7 and the internal space 4, and a first valve part 21C that separates from and comes into contact with the first valve seat surface 31A to open and close the intermediate communication passage 26; wherein the opening area of the first valve part 21C is less than the opening area of the intermediate communication passage 26.

Description

technical field [0001] The present invention relates to a capacity control valve for variably controlling the capacity or pressure of a working fluid, and more particularly to a capacity control valve for controlling the discharge rate of a variable capacity compressor used in an air-conditioning system of an automobile or the like according to a pressure load Capacity control valve. Background technique [0002] A swash plate type variable displacement compressor used in an air-conditioning system such as an automobile includes: a rotating shaft driven to rotate by the rotational force of the engine; a swash plate connected to the rotating shaft so that the inclination angle can be changed; For compression pistons, etc., the discharge amount of refrigerant is controlled by changing the inclination angle of the swash plate and changing the stroke of the piston. [0003] Using the suction pressure of the suction chamber that sucks in the refrigerant, the discharge pressure o...
