DEVICE FOR METERED DRAINAGE OF LIQUID Russian patent published in 1995 - IPC

FIELD: liquid metering systems. SUBSTANCE: housing 1 is made in form of two identical reservoirs 2 and 3 connected by means of transverse branch pipe 4. Reservoirs 2 and 3 are provided with floats 7 and 8, respectively for turning on common axle 6. Secured coaxially relative to floats 7 and 8 are blocks 10 and 11 connected with valves 14 and 15 by means of rods 12 and 13; valves 14 and 15 close outlet holes of reservoirs 2 and 3. Floats 7 and 8 are turned relative to each other through 180 deg. Provided in axle 6 in area of transverse branch pipe 4 are passages 18 and 19 which connect inlet hole 5 in turn with reservoirs 2 and 3 when axle 6 is turned. Axle 6 is turned by means of floats 7 and 8 after reservoir 2 or 3 has been filled to required level. Process is effected automatically. EFFECT: enhanced accuracy of metering since no liquid is allowed to reservoir in the course of draining. 3 dwg
