US 6,202,684 B1 · Pressure control system

Abstract

A pressure control system for controlling pressure in a fluid system includes a compressor for producing pressurized fluid coupled to a rotor valve, a pressure controller, and a visual low-pressure indicator. A manifold directly supports the valve and has, integrated within, the pressure controller, the low-pressure indicator, and the output connections. The pressure controller includes a plunger and a spring communicating with the fluid system. The pressurized fluid acts against the plunger and the spring, and excess fluid is discharged when pressure exceeds a predetermined value. The low-pressure indicator includes a diaphragm movable away from a transparent window, providing a visual indication of the pressure within the system. The manifold assembly provides connectors for supplying fluid to the system.

Dependent claims

A pressure control system for controlling the pressure in at least a first and second fluid system, each fluid system having a respective supply conduit, comprising:

an input conduit for receiving fluid from a fluid source,
means for directing fluid from the input conduit to at least one of the first and second supply conduits, and
a pressure control housing including a manifold assembly;
the conduits being formed within the manifold assembly;
wherein the manifold assembly includes:
a connector interface for supplying fluid directly to the respective fluid system;
