Abstract
A vacuum system for use with a deoxygenator system includes a housing, a movable assembly positioned within the housing, and a biasing mechanism coupling the movable assembly to the housing. The movable assembly is movable between a first position and a second position within the housing to form a low pressure area between the housing and the movable assembly. A control system including at least one pressure source is arranged in fluid communication with the low pressure area. The control system is operable to selectively communicate fluid from the at least one pressure source to the housing to form the low pressure area.

A vacuum system for use with a deoxygenator system comprising:
- a housing;
- a movable assembly positioned within the housing;
- a biasing mechanism coupling the movable assembly to the housing, wherein the movable assembly is movable between a first position and a second position within the housing to form a low pressure area between the housing and the movable assembly;
- and
- a control system including at least one pressure source arranged in fluid communication with the low pressure area, wherein the control system is operable to selectively communicate fluid from the at least one pressure source to the housing form the low pressure area.
A method of operating a deoxygenator system, comprising:
- supplying a high pressure fluid to a housing;
- moving a movable assembly from a first position to a second position in response to the high pressure fluid;
- and
- creating a vacuum within a chamber defined between the movable assembly and the housing.
