Abstract
Abstract The discriminator includes a housing having an inlet passage and a pair of outlet passages opposite the inlet passage, the inlet passage having a reduced diameter passageway for creating a high velocity fluid stream. A pair of lateral passages communicate with the junction of the inlet and outlet passages and a bias passage communicates between the inlet passage and one of the lateral passages to create a low-pressure condition on one side of the fluid stream and thereby direct it through one of the outlet passages. A feedback passage communicates between the one outlet passage and the one lateral passage and deflects the fluid stream from the one outlet to the other outlet passage in response to a predetermined minimum pressure. A flow maintaining passage communicates with the other outlet passage and the other lateral passage to create a low-pressure condition on the other side of the fluid stream and thereby maintains fluid communication between the inlet and other outlet passages.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
168 words
A fluid-pressure disCriminator comprising a housing, a fluid inlet in said housing for admitting fluid under pressure and including a first passage in said housing in communication with said inlet for providing a stream of fluid, first and second fluid outlet passages disposed generally opposite said stream for receiving the stream of fluid, a second passage in communication with said fluid inlet for biasing the stream of fluid into said first fluid outlet, and a third passage in communication with said first fluid outlet and directed to flow fluid substantially laterally against the fluid stream in said first passage on one side thereof for diverting the fluid stream from said first outlet passage to said second outlet passage in response to a fluid inlet pressure above a predetermined pressure, including a fourth passage in communication with said second fluid outlet passage and with said first passage on the opposite side of the fluid stream in said first passage for maintaining flow of fluid to said second outlet passage.
Claim 2
Dependent Claim
168 words
A fluid-pressure disCriminator comprising a housing, a fluid inlet in said housing for admitting fluid under pressure and including a first passage in said housing in communication with said inlet for providing a stream of fluid, first and second fluid outlet passages disposed generally opposite said stream for receiving the stream of fluid, a second passage in communication with said fluid inlet for biasing the stream of fluid into said first fluid outlet, and a third passage in communication with said first fluid outlet and directed to flow fluid substantially laterally against the fluid stream in said first passage on one side thereof for diverting the fluid stream from said first outlet passage to said second outlet passage in response to a fluid inlet pressure above a predetermined pressure, including a fourth passage in communication with said second fluid outlet passage and with said first passage on the opposite side of the fluid stream in said first passage for maintaining flow of fluid to said second outlet passage.
Claim 3
Dependent Claim
45 words
A discriminator according to claim 1 wherein said fourth passage is arranged to create a low-pressure condition on said opposite side of the fluid stream, the fluid stream being thereby biased to said opposite side to maintain flow of fluid to said second outlet passage.
Claim 4
Dependent Claim
214 words
A fluid-pressure discriminator comprising a housing, a fluid inlet in said housing for admitting fluid under pressure and including a first passage in said housing in communication with said inlet for providing a stream of fluid, first and second fluid outlet passages disposed generally opposite said stream for receiving the stream of fluid, a second passage in communication with said fluid inlet for biasing the stream of fluid into said first fluid outlet, and a third passage in communication with said first fluid outlet and directed to flow fluid substantially laterally against the fluid stream in said first passage on one side thereof for diverting the fluid stream from said first outlet passage to said second outlet passage in response to a fluid inlet pressure above a predetermined pressure, said second passage being arranged to create a low-pressure condition on said one side of the fluid stream, the fluid stream being thereby biased toward said one side for flow to said first fluid outlet passage when the fluid inlet pressure is below said predetermined pressure, and a fourth passage in communication with said second fluid outlet passage and with said first passage on the opposite side of the fluid stream in said first passage for maintaining flow of fluid to said second outlet passage.
Claim 5
Dependent Claim
214 words
A fluid-pressure discriminator comprising a housing, a fluid inlet in said housing for admitting fluid under pressure and including a first passage in said housing in communication with said inlet for providing a stream of fluid, first and second fluid outlet passages disposed generally opposite said stream for receiving the stream of fluid, a second passage in communication with said fluid inlet for biasing the stream of fluid into said first fluid outlet, and a third passage in communication with said first fluid outlet and directed to flow fluid substantially laterally against the fluid stream in said first passage on one side thereof for diverting the fluid stream from said first outlet passage to said second outlet passage in response to a fluid inlet pressure above a predetermined pressure, said second passage being arranged to create a low-pressure condition on said one side of the fluid stream, the fluid stream being thereby biased toward said one side for flow to said first fluid outlet passage when the fluid inlet pressure is below said predetermined pressure, and a fourth passage in communication with said second fluid outlet passage and with said first passage on the opposite side of the fluid stream in said first passage for maintaining flow of fluid to said second outlet passage.
