Operation
Installed directly downstream from the air-oil separator, the MPCV provides two functions:
- At start-up, the valve stays closed up to a preset level and then opens to maintain a minimum pressure in the air-oil separator. This assures pressure for lubricating the compressor, reduces oil foaming and protects the air-oil separator element.
- At shut-down, the check valve closes to prevent back flow through the compressor.
