Abstract
The present invention relates to a throttling structure for use in a fluid pressure device. A nozzle passage is formed between a primary side port and a nozzle back pressure chamber. A throttling mechanism made up from a plurality of orifice plates is disposed in the nozzle passage. Small diameter opening holes, which are smaller in diameter than the nozzle passage, are provided in the orifice plates. Outer edge portions of the orifice plates are retained in a second body part via seal members. Further, the orifice plates are separated mutually from each other by a predetermined distance along the direction of extension of the nozzle passage.
