Pulsator Combined With Claw Patents (Class 119/14.37)
  • Patent number: 8356577
    Abstract: A combination of a teat cup and a flexible milk tube is shown. The flexible milk tube has a main duct and a plurality of secondary ducts for discharging milk from the teat cup and for applying vacuum in the teat cup. The main duct is confined by a duct wall extending around the main duct. The secondary ducts are included in the duct wall of the main duct. By including the plurality of secondary ducts in the duct wall of the main duct the flexible milk tube as a whole has a smaller cross-section than that of the known milk tube. The plurality of secondary ducts no longer need separate duct walls forming separate tubes either connected or not with the flexible milk tube comprising the main duct. This results in space saving.

  • Patent number: 8240272
    Abstract: In a milking cluster of teat cups, each teat cup has a port in the form of a nozzle disposed in the head portion of the flexible liner (3) of the teat cup. The milking cluster includes a distributor having a fluid inlet aid outlets connected to the nozzles of the cups. The distributor inlet is connected to a supply of filtered air under atmospheric pressure by a first valve which is operable to admit air to the distributor in order to regulate the level of vacuum present in the teat cup liners during a milking cycle. It is connected to a delivery line for supplying sanitising fluid, which is utilised to treat the teats and teat cups in a cleansing cycle following the milking cycle, by a second valve operable to maintain the delivery line primed with sanitising fluid preparatory to initiation of the cleansing cycle.

  • Patent number: 6755152
    Abstract: There is provided an apparatus and method for monitoring pulsation of a milking system in a dairy facility. The milking system includes vacuum hoses that extend from a vacuum source to a milking claw. The pressure in each vacuum hose is changed by a pulsator, with the vacuum hoses being out of phase with one another. The pressure sensors are coupled to the respective vacuum hoses, which sensors monitor the pressure pulsations to ensure that the pulsator is operating satisfactorily. The pressure sensors are coupled to the vacuum hoses by way of passageways or hoses. A bypass is provided between the passageways so as to provide air circulation in the otherwise dead air space in these passageways. The bypass is small so as to not interfere with the pressure measurements by the sensors and is located in close proximity to the pressure sensors so as to minimize the amount of dead air space.
