专利汇可以提供Milking machine专利检索，专利查询，专利分析的服务。并且A duct under partial vacuum leads mlk from the teat cup cluster and creates a milking milk therein, the duct having a regulating valve operable to vary the milking vacuum. A device for sensing changes in the rate of milk flow through this duct is connected to control means for operating the regulating valve to decrease the milking vacuum from a working value to an idling value in response to a decrease in the milk flow rate and in increase the milking vacuum from an idling to a working value in response to an increase in said rate.，下面是Milking machine专利的具体信息内容。

权利要求

1. In a milking machine, the combination of a teat cup cluster, a duct under partial vacuum connected to said cluster for leading milk therefrom and for creating a milking vacuum in the cluster, a device for sensing changes in the rate of milk flow through said duct, a regulating valve connected in said duct and operable to vary said milking vacuum, and control means operatively connected to the regulating valve and sensing device for operating said valve to decrease said milking vacuum from a working value to an idling value in response to a decrease in said flow rate and to increase the milking vacuum from an idling value to a working value in response to an increase in said flow rate.

2. The combination defined in claim 1, in which said regulating valve includes a housing and a movable member dividing the housing into two chambers, one of said chambers interconnecting different parts of said duct, the other chamber having a pneumatic connection to said control means, said member being movable by the control means through said pneumatic connection to effect said decrease and increase of the milking vacuum.

3. The combination defined in claim 1, in which said control means includes a pneumatic tube connected to the regulating valve, and valve means operable by said sensing device for varying the pressure in said tube.

4. The combination defined in claim 1, in which said control means include a pneumatic tube connected to the regulating valve, and valve means operable by said sensing device for varying the pressure in said tube, said regulating valve including a housing and a movable member dividing the housing into two chambers, one of said chambers interconnecting different parts of said duct, the other chamber communicating with said pneumatic tube, said member being movable in response to pressure changes in said tube to effect said decrease and increase of the milking vacuum.
