  • Liquid pressure regulator
    Patent number: 6578601
    Abstract: A liquid pressure regulator assembly includes an inlet portion through which the liquid enters the regulator assembly. The inlet portion includes a piston member which is engageable with a plunger portion. A housing portion encloses the plunger portion and is sealingly engageable with the inlet portion. The housing defines passageways for the liquid to pass through the regulator assembly. A spring member located between said inlet portion and said plunger portion biases the plunger portion to an operating position away from said inlet portion to permit liquid to flow through the assembly. Separated support members are provided between the piston member and the plunger portion to permit axial movement of the plunger portion relative to the inlet portion to predeterminely control the flow of liquid through the regulator assembly.
