<p>An improved pressure control system for controlling pressure in a fluid system comprising a compressor (1) for producing pressurised fluid coupled to a rotor valve (2), a pressure controller (11) and a visual low pressure indicator (12). A manifold (14) (Figure 3 not shown) directly supports the valve and has integrated there within the pressure controller (11) and low pressure indicator (12) and output connectors (8,9). The pressure controller (11) includes plunger (44) and spring (42) communicating with the fluid system. The pressurised fluid acts against the plunger and spring and excess fluid is discharged when pressure exceeds a predetermined valve. A low pressure indicator (12) includes a diaphragm (34) movable away from a transparent window (38) providing a visual indication of the pressure within the system. The manifold assembly provides connectors for supply of fluid to the system. <IMAGE></p> |
