ABSTRACT:
Teat cups are pulsed by a valve in a duct leading from the shell into the pulsation space between a resilient inflation and the shell. The valve alternately opens the pulsation space to ambient pressure and to a source of vacuum. The source of vacuum in the receiver or milk lines is in communication with the pulsation space through a tube or passage that is controlled by the valve. A timer connected to a solenoid actuator for the valve unseats the valve to allow air to enter the pulsation space, whereupon the inflation assumes a normal configuration. Upon seating to close ambient air entry while establishing vacuum to the space, the vacuum flattens the inflation. The timer sequences the air movement to ensure that milk flowing to the receiver clears the milk from the inflation and prevents back flow to the animal's teats.
