Abstract
An example laminate assembly pressurization arrangement includes a plurality of laminations arranged in a laminate stack. The plurality of laminations are movable between sealed positions and unsealed positions relative to each other. An end plate is adjacent the laminate stack. A housing is configured to establish a first volume together with the end plate. A first group of tie rods is directly secured to the end plate and is configured to move the end plate to a first position that holds the plurality of laminations in sealed positions. A second group of tie rods is directly secured to the housing. Pressurizing the first volume limits movement of the end plate away from the first position.
Claims17
A laminate assembly pressurization arrangement comprising:
- a plurality of laminations arranged in a laminate stack, the plurality of laminations moveable between sealed positions and unsealed positions relative to each other;
- an endplate adjacent the laminate stack;
- a housing configured to establish a first volume together with the endplate;
- a first group of tie rods secured relative to the endplate and configured to move the endplate to a first position that holds the plurality of laminations in sealed positions, wherein the first group of tie rods extend through a channel in the housing and are mechanically separated from the housing;
- and
- a second group of tie rods secured relative to the housing, wherein pressurizing the first volume limits movement of the endplate away from the first position.
A laminate assembly pressurization arrangement comprising:
- a laminate assembly including a plurality of laminations;
- a first endplate adjacent the plurality of laminations establishing a portion of a first enclosed volume;
- a second endplate adjacent the laminations, the second endplate establishing a portion of a second enclosed volume, wherein the second endplate is configured to urge the laminations toward sealed positions relative to each other when the second enclosed volume is pressurized;
- and
- a first tie rod arrangement extending through openings in the first end plate and configured to hold the plurality of laminations in a sealed position;
- and
- a first housing configured to establish the first enclosed volume together with the first endplate, wherein the first housing is secured relative to the laminate assembly separately from the first endplate.
A laminate assembly pressurization arrangement comprising:
- a plurality of laminations arranged in a laminate stack;
- a first endplate adjacent the laminate stack;
- a first housing configured to establish a first enclosed volume together with the first endplate;
- and
- a first group of tie rods secured relative to the first endplate and configured to move the endplate to a first position that holds the plurality of laminations in sealed positions, wherein the first group of tie rods extend through a channel in the first housing and are mechanically separated from the first housing.
