ABSTRACT:
A valve assembly for mounting in the outlet of a teat cup assembly. The valve assembly comprises a valve housing connected to the outlet of a teat cup assembly. The housing includes a nipple formed in the bottom portion thereof for connection to a milk suction line. A valve member is mounted inside the valve housing and adapted to seat on a valve seat in the housing when the interior of the housing is exposed to atmospheric pressure. The valve assembly further includes a plunger means slidably mounted in an opening in the wall of the valve housing, and the plunger means is adapted to slide inwardly into the valve housing when the pressure in the housing falls below atmospheric pressure. The inward movement of the plunger means is adapted to dislodge the valve member from its seated position in the valve housing.
