Abstract
Abstract The distributing device for supplying compressed air to the jet nozzles of swirl chambers relates to apparatus for making a self-twisted product. The distributing device comprises a stationary hollow housing with apertures and a passageway for supplying compressed air, and also a rotary distributing member of a cylindrical shape, in the form of a sleeve with a bottom, mounted in the internal space of the housing with a gap left therebetween, this gap permanently communicating with the compressed air supply passageway. The open end of the distributing member faces the compressed air supply passageway and, the member having passages made in the cylindrical wall thereof, periodically communicating through the apertures in the housing with the jet nozzles of the swirl chambers, to supply compressed air thereinto. The disclosed structure of the distributing device enables to increase the reliability of its performance and to provide for the stability of the flow of the process of obtaining the self-twisted product.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
158 words
A distributing device for supplying compressed air to the jet nozzles of the swirl chambers of an apparatus for making a self-twisted product, comprising: a stationary hollow housing; a compressed air supply passageway in said housing; apertures in said housing and communicating with the jet nozzles of the swirl chambers; a rotary cylindrical distributing member accommodated in the internal space of said hollow housing; a gap defined between said housing and a cylindrical surface of said distributing member, permanently communicating with said compressed air supply passageway; said cylindrical distributing member being shaped as a sleeve with a bottom, a cylindrical wall and an open end facing said compressed air supply passageway; passages in the cylindrical wall of said distributing member, adapted, with said cylindrical distributing member rotating in operation, to communicate periodically with the jet nozzles of the swirl chambers through said apertures in said housing, to supply compressed air to the jet nozzles of the swirl chambers.
Claim 2
Dependent Claim
158 words
A distributing device for supplying compressed air to the jet nozzles of the swirl chambers of an apparatus for making a self-twisted product, comprising: a stationary hollow housing; a compressed air supply passageway in said housing; apertures in said housing and communicating with the jet nozzles of the swirl chambers; a rotary cylindrical distributing member accommodated in the internal space of said hollow housing; a gap defined between said housing and a cylindrical surface of said distributing member, permanently communicating with said compressed air supply passageway; said cylindrical distributing member being shaped as a sleeve with a bottom, a cylindrical wall and an open end facing said compressed air supply passageway; passages in the cylindrical wall of said distributing member, adapted, with said cylindrical distributing member rotating in operation, to communicate periodically with the jet nozzles of the swirl chambers through said apertures in said housing, to supply compressed air to the jet nozzles of the swirl chambers.
Claim 3
Dependent Claim
32 words
A distributing device as claimed in claim 1, wherein the size of said gap is selected to pass substantially less compressed air than any one of said passages of said distributing member.
Claim 4
Dependent Claim
45 words
A distributing device as claimed in claim 1, wherein said housing has an end in the form of a lid, said lid formed with said compressed air supply passageway and said cylindrical distributing member also defining a gap between said open thereof and said lid.
Claim 5
Dependent Claim
26 words
A distributing device as claimed in claim 1, wherein a driven shaft is connected to said bottom of said distributing member for rotating said distributing member.
Claim 6
Dependent Claim
31 words
A distributing device as claimed in claim 4, wherein said housing has an internal space, and bearings situated in said internal space and said driven shaft being journalled in said bearings.
