Abstract
A vacuum assembly 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 create a low pressure area between the housing and a first portion of the movable assembly.
Claims17
A vacuum assembly comprising:
- a housing;
- a movable assembly positioned within the housing, the movable assembly including a first portion and a second portion, a first chamber being formed between the housing and the first portion, a second chamber being formed between the housing and the second portion, and a third chamber being formed between the housing and part of the movable assembly between the first portion and the second portion;
- and
- 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 create a low pressure area between the housing and a first portion of the movable assembly.

A fuel system comprising:
- a deoxygenation system;
- a fuel pump for providing fuel to the deoxygenation system;
- and
- a vacuum operably coupled to the deoxygenation system to selectively remove oxygen from fuel within the deoxygenation system, the vacuum being operable automatically in response to one or more pressures external to the vacuum, the vacuum including:
- a housing;
- and
- a movable assembly movable within the housing between a first position and a second position, wherein movement of the movable assembly from the first position to the second position generates a low pressure area within the housing, wherein a first chamber is formed between the housing and the first portion a second chamber is formed between the housing and the second portion and a third chamber is formed between the housing and part of the movable assembly between the first portion and the second portion.
