Abstract
An outlet from the claw housing is controlled by a valve which allows a small discharge flow even in its closed position. The valve is operated by a pneumatic member comprising two flexible diaphragms defining between them a working chamber, the diaphragms having unequal areas and being exposed outside the working chamber to the pressure in the milk manifold of the claw. Thus, the valve operating member is actuated by changes in the difference between the pressures in the manifold and the working chamber.
