  • Patent number: 6799598
    Abstract: In a two-way solenoid vale, a small diameter portion of a nozzle portion is fitted in a small diameter portion receiving part communicating with an output pressure oil passage and a large diameter portion is fitted in a large diameter portion receiving part communicating with a supply pressure oil passage. An opening of a through-hole formed in the nozzle portion faces the output pressure oil passage by way of the small diameter portion receiving part, and an inner end of the through-hole is opened and closed by a plunger and communicates with a drain port. An orifice port communicating with the through-hole is opened to the large diameter portion receiving part and communicates with the supply pressure oil passage. Since the orifice port is disposed in the solenoid valve, a separate plate for an orifice is not required, oil passage is simplified and the solenoid valve can be installed in an optional position.
