Definitions

  • the opening / closing member may have an annular portion that is relatively slidable with respect to the pressure sensitive valve member. According to this, since the annular portion is continuous without interruption in the circumferential direction, the through hole of the pressure sensitive valve member can be reliably closed by the annular portion.
  • the elastic body may press the opening / closing member toward the flange portion formed on the pressure-sensitive body side of the through hole of the pressure-sensitive valve member. According to this, it is possible to secure the closed state of the through hole of the pressure sensitive valve member by the opening / closing member while positioning the closed position of the opening / closing member.
  • the sub-valve 54 is composed of a main sub-valve body 51 and an open end surface of the fixed iron core 82, that is, a sub-valve seat 82a formed on the end surface on the left side of the fixed iron core 82 in the axial direction, and is a shaft of the main sub-valve body 51.
  • the sub-valve 54 opens and closes when the step portion 51b on the right side in the direction is brought into contact with and separated from the sub-valve seat 82a.
  • the capacity control valve V1 has a valve housing 10 made of a metal material or a resin material, and a main / sub valve body 51 arranged so as to reciprocate in the valve housing 10 in the axial direction.
  • the valve housing 10 has a bottomed substantially cylindrical shape by press-fitting the partition adjusting member 11 into the left end portion in the axial direction in a substantially sealed shape.
  • the partition adjusting member 11 can adjust the urging force of the pressure sensitive body 60 by adjusting the installation position of the valve housing 10 in the axial direction.
  • the pressure-sensitive body 60 is arranged in the pressure-sensitive chamber 40, and the end face 70a on the right side in the axial direction of the adapter 70 is moved by the urging force for moving the adapter 70 to the right in the axial direction by the coil spring 62 and the bellows core 61. It is designed to be seated on the pressure-sensitive valve seat 52a of the pressure-sensitive valve member 52. Further, the adapter 70 is adapted to apply a force to the left in the axial direction according to the suction pressure Ps in the intermediate communication passage 55.
  • the inner peripheral surface of the base 90a of the opening / closing member 90 is slidable with the outer peripheral surface of the base 52b of the pressure sensitive valve member 52. Specifically, a minute gap is formed between the inner peripheral surface of the base 90a of the opening / closing member 90 and the outer peripheral surface of the base 52b of the pressure sensitive valve member 52 by slightly separating them in the radial direction. Is smoothly relative to the pressure sensitive valve member 52 in the axial direction.
  • the end surface 90c of the base portion 90a of the opening / closing member 90 is pressed toward the side surface 52e of the flange portion 52c of the pressure sensitive valve member 52 by the urging force of the second coil spring 92.
  • the spring load of the second coil spring 92 acts on the first coil spring 91 via the protruding portion 90b of the opening / closing member 90, but as described above, the set load of the first coil spring 91 is the second. Since it is larger than the maximum spring load of the two coil springs 92, the first coil spring 91 does not contract and the state of the set length (mounting length) is maintained.
  • the through hole 52d of the pressure-sensitive valve member 52 is formed on the right side in the axial direction with respect to the side surface 52e on the right side in the axial direction of the flange portion 52c, and the end surface 90c of the base 90a of the opening / closing member 90 is the flange portion of the pressure-sensitive valve member 52.
  • the opening / closing member 90 is radially superimposed on the through hole 52d and the through hole 52d is closed from the state of being pressed against the side surface 52e of the 52c until the opening / closing member 90 is radially moved to the axial position of the opening end on the left side in the axial direction of the through hole 52d. It is designed to maintain the state of being used.
  • the normal control time will be described.
  • the flow rate of the fluid from the Pd port 12 to the Pc port 14 is controlled by adjusting the opening degree and the opening time of the main valve 50 by the duty control of the capacitance control valve V1.
  • the opening / closing member 90 moves with respect to the valve housing 10 because the first coil spring 91 does not expand / contract and only the second coil spring 92 expands / contracts with respect to the axial reciprocating movement of the main / sub valve body 51. Is regulated.
  • the stroke of the main / sub valve body 51 for adjusting the opening degree of the main valve 50 by the duty control of the capacity control valve V2 is from the time when the main valve 50 is fully opened (see FIG. 5).
  • the opening / closing member 290 superimposes on the through hole 52d in the radial direction and penetrates. The state in which the hole 52d is closed is maintained (see FIG. 6).
  • the opening / closing member 490 has a cylindrical base portion 490a as an annular portion that is externally fitted to the base portion 52b of the pressure sensitive valve member 52.
  • a groove 490b extending in the circumferential direction is formed on the outer peripheral surface of the base portion 490a.
  • a substantially C-shaped fixing member 493 as a regulating means is inserted and fixed in the groove 490b.
  • the fixing member 493 is provided with a plurality of through holes 493a penetrating in the axial direction in the circumferential direction. Further, the through holes 493a may not be evenly arranged.
