Abstract: The invention relates to a milking plant wherein the vibrations and sound emissions thereof are significantly reduced. In said inventive milking plant, a vacuum control valve (500) is directly connected to a vacuum compensation tank (200). The vacuum control valve (500) leads into the vacuum compensation tank (200) via a diffusor (501). The vacuum control valve (500) is enclosed in a cylindrical container (503). Preferably, the vacuum pump (110) and the vacuum compensation tank (200) are connected to each other via a main line (150) which is embodied in the form of two bent, flexible hoses. Preferably, the main line (150) leads tangentially into the vacuum compensation tank (200). The invention also relates to a method for reducing sound emissions in one such milking plant. According to said method, the flow speed of the air in the air-guiding parts (150, 200, 300, 302, 403, 420) of the milking plant is reduced.

Abstract: An air-flow meter for milking machines, comprising an enclosed housing with a connection to a line that is to be tested for flow and pressure and with an air-intake mechanism with a variable cross-section. The air-intake mechanism is an air intake with a slot-shaped cross-section. A rotating cylinder is accommodated inside the housing and operates in conjunction with the slotted intake. The cylinder has a breach that tapers out along a considerable length of its circumference. The longitudinal axis of the intake parallels the axis the cylinder rotates around, the free cross-section of the intake is only a fraction of length of the breach along the circumference of the cylinder, and any area of the breach can be aligned with the air intake by rotating the cylinder.
