专利汇可以提供Teat cup assembly专利检索,专利查询,专利分析的服务。并且A flexible liner known as an inflation for a teat cup of a milking machine wherein the opening for receiving the cow''s teat has radially extending corrugations about its edge so as to be expansible, such capacity to expand being augmented by a distensible knuckle spaced from and substantially parallel to the edge of the opening. In a preferred embodiment, the corrugations have a spiral configuration so as to form means spaced from the opening for distending as the opening is expanded. The spiral corrugations serve a purpose of causing washing and/or rinsing fluid to swirl as it passes through the inflation whereby a more effective cleaning results. The shell for the inflation includes means at the upper edge for swirling the washing and/or rinsing fluid and also for centering the inflation during the washing operation. The conduit for admitting air pulsations in the milking operation and washing fluid in the washing operation joins the shell at a tangent so as to direct washing and/or rinsing fluid into a helical swirling path in the annular space between the inflation and the shell. Optionally the shell may be convoluted to guide the fluid in a helical through the annular space and, further, to provide additional strength to the shell.,下面是Teat cup assembly专利的具体信息内容。

1. An inflation for a teat cup assembly, said inflation having a portion with a centrally located aperture for receiving the teat of a farm animal, a plurality of channels extending outwardly in the underside of said portion from said aperture, said channels being canted relative to said aperture whereby fluid flowing out of said aperture from the underside of said portion is swirled.
2. An inflation in accordance with claim 1 wherein said channels are spiral-shaped.
3. An inflation in accordance with claim 2 wherein said portion is resilient.
4. An inflation in accordance with claim 3 wherein said channels comprise a plurality of corrugations.
5. An inflation for a teat cup assembly, said inflation having a portion with a centrally located aperture for receiving the teat of a farm animal, a plurality of corrugations included in said portions extending outwardly from said aperture, said corrugations being curved whereby fluid flowing out of said aperture from the interior of said inflation is swirled.
6. An inflation in accordance with claim 5 wherein at least five of said corrugations are provided which are spaced an equal amount apart about said aperture.
7. An inflation in accordance with claim 5 wherein said portion is composed of a resilient material.
8. An inflation in accordance with claim 7 wherein the included angle between a tangent to the side of each of said corrugations at a location on said portion opposite said aperture and a line through said location and the center of said aperture is at least about 45*.
9. An inflation for a teat cup assembly, said inflation being composed of resilient material and comprising an integral relatively thin upper portion including a centrally located expansible aperture for receiving the teat of a farm animal, a plurality of corrugation means extending outwardly in an irregular path from an edge defining said aperture whereby, when said aperture is dilated, said corrugation means tends to flatten in a first direction to grip an animal''s teat in a substantially air tight seal, and distention means including passages in the underside of said portion, spaced from the edge of said aperture adapted to extend outwardly and in a second direction substantially transverse to said first direction when said aperture is dilated.
10. An inflation in accordance with claim 9 wherein said distention means comprises corrugations which at least in part are substantially parallel to the nearest portion of said edGe.
11. An inflation in accordance with claim 9, wherein further corrugation means in said upper portion extends substantially radially from said aperture, said first mentioned corrugation means joining said further corrugation means.
12. An inflation for a teat cup assembly, said inflation being composed of resilient material and having a relatively thin upper portion including a centrally located expansible aperture for receiving the teat of a farm animal in a substantially air tight seal, and distention means including passages in the underside of said portion, spaced from the edge of said aperture adapted to distend outwardly when said aperture is dilated, said passages being curved in a general spiral configuration, whereby washing and/or rinsing fluid is swirled during cleaning.
13. The inflation of claim 12 wherein the edge of said aperture includes an upright flange.
14. In an apparatus in accordance with claim 13, wherein said first mentioned corrugation means and said further corrugation means join to form a spiral-shaped member.
15. In an apparatus in accordance with claim 14 wherein said web includes a plurality of said spiral-shaped members.
16. In an apparatus in accordance with claim 13 wherein said first mentioned corrugation means encircles said opening and there are a plurality of said further corrugation means.
17. Edge means in accordance with claim 11 wherein said flange is rounded in cross-section.
