    • The invention relates to a valve apparatus for adjusting parallel flows. Moreover, the invention comprises a method for manufacturing a valve member belonging to said apparatus, a method for adjusting parallel flows, a method for washing said apparatus and a dosing apparatus. The valve apparatus includes at least two valve members 1, la movable with respect to each other, in which members there are provided parallel channels 3 for said flows. The ends 4 of the channels are located on opposite sliding surfaces 2 belonging to the valve members, so that when the channel ends are matched, the flow paths are open, and when the channel ends are deviated, the flow paths are closed. Moreover, in at least one of the opposite sliding surfaces 2, there are made grooves 5 in between the channel ends 4. The grooves 5 can serve as washing channels in order to prevent contamination between parallel flows, in addition to which they serve, when manufacturing the valve member, as collectors of grinding dust and grinding paste. The grooves also make it possible to wash the sliding surfaces at a pressure that overcomes the force of the spring 19 charging the valve members, thus pushing the sliding surfaces apart. The flow adjustment according to the invention can be applied in simultaneously feeding small batches of liquid onto a microtiter plate 13 containing fluid positions 12 in a matrix-like fashion.
    • 阀装置(A)包括至少两个阀构件(1,1A),相对于彼此可移动的,并包括形成的具有阀的相对滑动面的端部的平行流路部件的通道。 当通道结束的比赛中,流动路径确定,但否则就不是。 在相对的滑动面中的至少一个,凹槽通道端部之间进行比较。 独立权利要求中包括了以下内容:(1)生产(1,1),其包括形成流动通道和槽,研磨,收集膏并从表面之间放电期间磨削的光滑表面与研磨膏和, 经由凹槽; (2)使用(A)调整并行流动,所以没有当流路是开放的,洗涤电路存在时,在较低的压力,其包括槽,以防止不同的流(3)洗涤(A)之间的污染哪所以没有当 并行流被中断,洗涤以比弹簧力大的压力下进行,因此除了没有滑动面和阀构件下降,从而使洗涤液在所述滑动面的整个区域,(4)的计量分发 包括装置(A),流体源被计量和泵用于以并行方式创建流动。
