Abstract
A piston housing manufactured by an additive manufacturing process is provided. The piston housing may comprise a plurality of chambers. The chambers may be in fluid communication with one another via non-linear fluid passageways. The non-linear fluid passageways may be defined in structural members configured to stiffen the piston housing.
Claims10
A piston housing, comprising:
- a body including:
- a first fluid chamber,
- a first structural member comprising a first hollow chamber defining a non-linear fluid passage, the non-linear fluid passage in fluid communication with the first fluid chamber,
- a second fluid chamber in series fluid communication with the first fluid chamber via the non-linear fluid passage,
- a second structural member configured as a box beam extending between the first fluid chamber and the second fluid chamber, the second structural member comprising a second hollow chamber,
- and
- a web disposed between the first structural member and the second structural member, wherein the web defines a hollow portion disposed between the first structural member and the second structural member,
- wherein the first structural member and the second structural member are formed from an additive manufacturing process,
- wherein the second structural member encloses the second hollow chamber.
6 more elements
A method, comprising:
- defining a piston housing design having a first fluid chamber design connected in series to a second fluid chamber design via a first structural member design, wherein the first structural member design includes a first hollow chamber defining a non-linear fluid passage and a second structural member design, wherein the second structural member design includes a box beam and a web;
- and
- manufacturing, by an additive manufacturing process, a piston housing based on the piston housing design, the piston housing comprising:
- a first fluid chamber, manufactured based on the first fluid chamber design;
- a second fluid chamber, manufactured based on the second fluid chamber design;
- a first structural member, manufactured based on the first structural member design, wherein the first structural member includes the first hollow chamber defining the non-linear fluid passage, whereby the first fluid chamber is in series fluid communication with the second fluid chamber;
- and
- a second structural member, manufactured based on the second structural member design, wherein the second structural member includes a second hollow chamber;
- wherein the second structural member includes the box beam disposed between the first fluid chamber and the second fluid chamber, the web disposed between the box beam and the non-linear fluid passage, wherein the web defines a hollow portion disposed between the box beam and the non-linear fluid passage,
- wherein the second structural member encloses the second hollow chamber.
