ABSTRACT:
There is disclosed a vacuum-pressure regulating device which is attached to a vacuum system in connection with a vacuum pump so that it serves to ensure a constant vacuum pressure in the vacuum system and then to supply vacuum pressure from the vacuum system, after reduced to the required extent, to a desired space. The vacuum-pressure supply device of the present invention is suitable for adjusting vacuum in vacuum systems for milking cows. The vacuum-pressure supply device consists of such a structure that there are provided two independent but adjacent sections built of casings, one of them is partitioned by a diaphragm to form 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 secured to each diaphragm is actuated according to a pressure difference between both sides of each diaphragm thereby automatically permitting air from the vacuum system or atmospheric air to flow into or flow out from each of the aforesaid chambers, thus maintaining two vacuum systems connected to the vacuum-pressure supply device as a desired high vacuum system and a desired low-pressure system respectively.
