Automatic multivalve manifold for systems for milking sheep, goats etc.

摘要

The manifold can be used in all milking systems using vacuum pneumatic systems. It must be positioned between the line carrying away the milk and the sheaths (rubber teats) positioned inside the casing. The novelty of the device is the pneumatic operation of the system of block valves and milk inflow, which makes it stable and insensitive to impact or to its spatial position. At the beginning of milking operations, the apparatus keeps the inflow of air to the milk-collecting line partially closed. The rubber teat is applied to the animal's teat, the system of absolute pressures between the chambers 1 and 2 (see appended tables 1 and 2) is modified such that the valve which has 2 different thrust surfaces, opens. It remains in this position until removal of the rubber teat causes a flow of air which, passing between the chambers 1 and 2, strikes the valve plate and closes the valve by aerodynamic pressure.
