Abstract

Изобретение относитс к дозирующим устройствам и позвол ет повысить надежность. Объем дозы настраиваетс узлом регулировани хода плавающего поршн 12 путем вращени его штанги 14 через втулку 22, выполненную с двум противоположно направленными винтовыми нарезками. В результате две части плавающего поршн 12, кажда из которых соосно установлена на одной из этих винтовых нарезок, сход тс или расход тс . Вращение штанги обеспечиваетс за счет того, что ее концы пропущены через соответствующие стороны двустороннего полого штока 13 плавающего поршн 12, который герметично надет на стержень 15, закрепленный концами в торцах цилиндра 1 эксцентрично его оси. Стержень 15 удерживает плавающий поршень от вращени . Дозируема жидкость поочередно нагнетаетс в полости цилиндра 1 через штуцер 6 дл подвода жидкостей, а вытесн етс через штуцер 7 дл отвода жидкостей кранов 5, их поворотные пробки размещены в торцах цилиндра 1, через которые герметично пропущен двусторонний полый шток 13. 1 з.п. ф-лы, 2 ил.The invention relates to metering devices and improves reliability. The dose volume is adjusted by the node controlling the stroke of the floating piston 12 by rotating its rod 14 through the sleeve 22, which is made with two oppositely directed screw cuts. As a result, the two parts of the floating piston 12, each of which coaxially mounted on one of these screw cuts, converge or diverge. The rotation of the rod is ensured by the fact that its ends are passed through the respective sides of the double-sided hollow rod 13 of the floating piston 12, which is hermetically fitted on the rod 15, which is fixed to the ends at the ends of the cylinder 1 eccentrically to its axis. The rod 15 keeps the floating piston from rotating. The dosing fluid is alternately injected into the cavity of the cylinder 1 through the fitting 6 for supplying liquids, and is forced out through the fitting 7 to drain the fluids of the taps 5, their rotary plugs are placed at the ends of the cylinder 1 through which the double-sided hollow rod 13 is hermetically passed 13. f-ly, 2 ill.

Claims

Claim

1. A liquid dispenser comprising a cylinder divided by a floating piston into two cavities in communication with a flow distributor, and a floating piston stroke control unit, characterized in that. what. in order to increase reliability by eliminating stagnant zones in the cylinder cavities, the floating stroke exclusion control unit is made in the form of a rod with two oppositely directed screw threads and rods. and the floating piston is equipped with a two-sided hollow rod, hermetically passed through the ends of the cylinder, and is made of two parts, each of which is coaxially mounted on one of the oppositely directed screw cuts of the rod, the free ends of which are passed through the corresponding side of the hollow rod, and parts of the floating rod are hermetically put on a rod fixed with ends at the ends of the cylinder eccentrically to its axis.

2. The dispenser according to π.1. Characterized in that the cylinder is equipped with a rotation drive and is mounted in supports, and the flow distributor is made in the form of taps, the rotary plugs of which are located at the ends of the cylinder.
