MILKING MACHINE WITH VACUUM CONTROLLER

摘要

a first chamber and a second chamber. The other section is partitioned also by a diaphragm to form a third and a fourth chamber. A valve is secured to each diaphragm and is actuated according to a presure difference between both sides of each diaphragm. This automatically permits air from the vacuum system to flow into or flow out from each of the chambers. Two vacuum systems are maintained and connected to the vaccum-pressure supply device acting, as a desired high vacuum system and a desired lowpressure system respectively.
