Control valve for variable displacement compressor using electromagnetic actuator |
摘要 |
<p>An electromagnetic actuator includes a cylinder (52), a stationary core (53) and a movable core (56) arranged in the cylinder (52), and a coil (61) located about the cylinder (52). The movable core (56) moves in the cylinder (52) in accordance with an electromagnetic force, which is generated between the stationary core (53) and the movable core (56) based on the current supply to the coil (61). The cylinder (52) includes a first cylindrical member (58) made of nonmagnetic material, and a second cylindrical member (59) made of magnetic material. The first cylindrical member (58) surrounds the stationary core (53) and the movable core (56). A part of the first cylindrical member (58) in the vicinity of the movable core (56) is made thin to form a small diameter portion (58b). The small diameter portion (58b) is fitted to the second cylindrical member (59). <IMAGE></p> |
