With Fluid Compression Patents (Class 119/14.27)
  • Patent number: 10542723
    Abstract: Improving milking system performance through the incorporation of a source of greater than atmospheric pressure air into a pulsator while limiting total pressure in the teat cup. The system is further improved by providing an improved supply of regulated vacuum to the milking cluster throughout the milking process. The system is further improved with a monitoring and detecting the functional failure of the pulsation assemblies. Additional system improvements are provided with the addition of a fresh air valve assembly, a wireless method of regulating vacuum levels and the remote location of a pulsator assembly in a basement style parlor.

  • Patent number: 9060493
    Abstract: A milking unit is proposed, comprising at least one milk hose (5, 30), having a first end section (6, 32) and a second end section (49), and a milk collecting component (7, 37), which is connected to the first end section (6, 32) of the milk hose (5, 30). The milk collecting component (7, 37) has at least one coupling element (1), which cooperates with the first end section (6, 32) of the milk hose (5, 30). A clamping element (9) is provided, which cooperates with the coupling element (1) so that an essentially fluid-tight connection is generated between the milk hose (5, 30) and the milk collecting component (7, 37).

  • Publication number: 20110239943
    Abstract: The invention relates to a milking device for milking animals, the required vacuum being, for example, generated by generating compressed air using a compressor and passing said compressed air through the system, the compressed air creating a vacuum at all required locations by means of the Venturi system. Because this vacuum differs at the various locations, the reduced pressure can be regulated precisely and adapted as required.

  • Patent number: 7290497
    Abstract: Device for pneumatically milking a cow, comprising a number of milk extractors, each comprising a teat cup as well as milk line connected to the lower end of the teat cup, which line leads from the teat cup to a collection chamber for the milk from the teat cup, each milk extractor being provided with a supply for a cleansing medium, such as a disinfectant, to the teat cup, in particular to a teat present in the teat cup, the supply comprising a line having an end portion with discharge end, and each milk extractor being provided with means for closing off the passage of the milk extraction at or downstream of the discharge end of the line for cleansing medium, preferably at that level, when discharging the cleansing medium, the closing means comprising a reciprocating closing body that can be moved between a position leaving the passage of the milk extractor free and a position closing it off, the closing body being provided with a squirt line forming the end portion with discharge end of the line for supply
