ABSTRACT:
Pressure controlled milk termination means wherein the top of a diaphragm is connected with the milk line by a vacuum communication conduit and the bottom of the diaphragm with the air line, but the bottom of the diaphragm having an air bleed aperture leading thereinto so that there is a constant differential of pressure acting on the diaphragm and of sufficient magnitude to bias the diaphragm upwardly. The diaphragm has coupled to it a valve member which is effective in closing the air bleed aperture, and the arrangement is such that when the air bleed aperture is closed, vacuum is supplied to a cylinder containing a piston which, when it lifts, lifts the claw away from the cow which has just been milked, and at the same time closes the vacuum communication conduit leading from the claw to the milk line.
