Abstract
A supersonic ejector assembly may include a housing manufactured from a solid piece of material, a first ejector assembly positioned in a first bore formed in the housing and secured therein by a first input side flange positioned over an input end of the first bore and an output side flange positioned over an output end of the first bore, and a second ejector assembly positioned in a second bore formed in the housing and secured therein by a second input side flange positioned over an input end of the second bore, the second bore terminating into the first bore proximate a suction input of the first ejector assembly.
Claims19
A supersonic ejector assembly comprising:
- a housing machined from a solid piece of material;
- a first bore formed through the housing;
- a second bore formed in the housing and not coaxially aligned with the first bore;
- a first ejector assembly positioned in the first bore formed in the housing and secured therein by a first input side flange positioned over an input end of the first bore and an output side flange positioned over an output end of the first bore;
- a second ejector assembly positioned in the second bore formed in the housing and secured therein by a second input side flange positioned over an input end of the second bore, the second bore terminating into the first bore proximate a suction input of the first ejector assembly;
- and
- a third bore formed in the housing, an output end of the third bore being in communication with a suction input of the second ejector assembly, and an input end of the third bore being in communication with an outer surface of the housing, the housing having a connection flange attached thereto and positioned over the input end of the third bore, and the second bore being formed in the housing between the first bore and the third bore and being configured to provide a communication between the first bore and the third bore.
A tandem supersonic ejector package, comprising:
- a unitary housing defining a first bore, a second bore, and a third bore;
- a first supersonic ejector assembly positioned in the first bore;
- and
- a second supersonic ejector assembly positioned in the second bore, wherein
- the second bore is not coaxially aligned with the first bore, the second bore is defined in the unitary housing between the first bore and the third bore, and is configured to provide a communication between the first bore and the third bore,
- an output of the second supersonic ejector assembly is in communication with a suction input of the first supersonic ejector assembly, and
- an output end of the third bore is in communication with a suction input of the second supersonic ejector assembly, and an input end of the third bore is in communication with an outer surface of the unitary housing, the unitary housing having a connection flange attached thereto and positioned over the input end of the third bore.
A tandem supersonic ejector package, comprising:
- a unitary metal or metal alloy block having the following bores formed therein:
- a) a first longitudinal bore formed through the block;
- b) a second bore formed into the block and terminating into the first longitudinal bore, wherein the second bore is not coaxially aligned with the first longitudinal bore;
- and
- c) a third bore formed into the block and terminating into the second bore;
- a first supersonic ejector assembly positioned in the first longitudinal bore;
- and
- a second supersonic ejector assembly positioned in the second bore,
- wherein a suction input of the first supersonic ejector assembly is in communication with the terminating end of the second bore, and a suction input of the second supersonic ejector assembly is in communication with the terminating end of the third bore,
- wherein an input end of the third bore is in communication with an outer surface of the unitary metal or metal alloy block, the unitary metal or metal alloy block having a connection flange attached thereto and positioned over the input end of the third bore, and
- wherein the second bore is formed between the first longitudinal bore and the third bore and is configured to provide a communication between the first longitudinal bore and the third bore.
