    • A collecting piece incorporating a pair of relatively movable members which function as a valve to control the supply of a vacuum to all four milking cups of a quarter milking machine while maintaining the milk supplied from each of the milking cups separate from one another. Each of the lines connected to each of the pair of movable members of the connecting piece terminate in an opening which is flush with a sliding surface on each of the two relatively movable members. Thus, rotating one of the members relative to the other will either bring the openings into alignment with each other or cause the openings to remain out of alignment with each other. If desired, a locking mechanism can be provided for locking the two relatively movable members in the two positions thereof.
    • 收集件包括一对可相对移动的构件,其作为阀,以控制向四分之一挤奶机的所有四个挤奶杯提供真空,同时保持从每个挤奶杯供应的牛奶彼此分离。 与连接件的一对可动件中的每一个连接的每条线终止于与两个相对移动的部件中的每一个上的滑动表面齐平的开口。 因此,相对于另一个旋转构件中的一个将使开口彼此对齐或使开口保持彼此不对准。 如果需要,可以设置锁定机构以将两个相对可移动的构件锁定在其两个位置。

    • A method for mechanical milk removal in which a predetermined underpressure is applied to the interior of a milking cup applied to a teat to remove the milk and, if desired, a pulsation of a teat rubber is effected at a predetermined frequency and intensity, and while the milking cup is in place the teat is stimulated for a predetermined interval prior to the principal milking operation. The invention also relates to an apparatus for executing the method comprising a pulsator connected on the one hand to an underpressure source and on the other hand to pulsator lines supplying the pulse spaces of the milking cup, the pulsator having two membranes which are interconnected by a linkage and which subdivide each pressure cell into two separate spaces, two spaces of which communicate with one another via a throttle, if desired adjustable, while the two other spaces of which are adapted to be selectively connected via a control unit to the underpressure source, and further comprising a switch-over device which is connected to the linkage and which serves to selectively connect one or two group(s) of pulsator lines to the underpressure source and to fresh atmospheric air.
