  • Milking vacuum fluctuation filter
    Patent number: 6439156
    Abstract: A milking system for milking a mammal such as a cow includes a source of vacuum applying vacuum through a conduit system to a plurality of milking clusters, each cluster having a plurality of teat cups supplying milk to a claw in response to pulsation vacuum controlled by a pulsator in the conduit system. The conduit system has a first portion upstream of the pulsator and applying vacuum from the source of vacuum to the pulsator. The conduit system has a second portion downstream of the pulsator and applying pulsation vacuum to the teat cups. The vacuum in the upstream portion of the conduit system is subject to fluctuation due to pulsation vacuum in the downstream portion. A vacuum fluctuation suppression filter is provided in the upstream portion of the conduit system attenuating the noted vacuum fluctuation.
