Abstract
The flow restrictor is a unitary one-piece element that can be fabricated from either metal or plastic by casting or molding. In use, it is press fitted into a bore in a solenoid valve body to provide a certain restrictive effect. It has a circular cylindrical central core that has a series of flanges that are axially spaced by gaps. Each flange has a circular outer edge that is interrupted by at least one axially extending through-notch. These notches are arranged to provide a tortuous path for the fluid flow, and sized to create a desired restriction. The restrictor provides two parallel flow paths, one, the tortuous path just described, and two, a through-hole through the core of the restrictor.
