Abstract
A three-dimensional monolithic diaphragm tank including a first portion having a first inner surface, a second portion having a second inner surface, and a deformable diaphragm extending from a peripheral junction with the first inner surface and the second inner surface. The first inner surface and the diaphragm defining a first chamber. The second inner surface and the diaphragm defining a second chamber. The first portion having an outlet port in fluid communication with the first chamber, and the second portion having an inlet port in fluid communication with the second chamber. The peripheral junction of the diaphragm and the first inner surface including an integral inner fillet having an inner radius.
Claims20
A method of fabricating a three-dimensional monolithic diaphragm tank, the method comprising:
- providing an energy beam array;
- providing a powder material bed including a powder material;
- transforming at least a portion of said powder material using a plurality of energy beams from said energy beam array to form a first hardened layer;
- rolling additional powder material onto said powder material bed over said first hardened layer;
- transforming at least a portion of said additional powder material using said plurality of energy beams from said energy beam array to form a second hardened layer;
- and
- repeating the rolling of said additional powder material onto said powder material bed and said transforming of said at least a portion of said additional powder material to form a three-dimensional monolithic positive expulsion diaphragm tank, said three-dimensional monolithic positive expulsion diaphragm tank comprising a deformable diaphragm arranged in a center cavity thereof, said three-dimensional monolithic positive expulsion diaphragm tank being formed by a plurality of hardened layers, wherein a peripheral junction of said diaphragm and an inner surface of said center cavity comprises an integral fillet having an inner radius.
