摘要： A pump including a first portion (2) with a metering cylinder (3) containing a plunger (4), and a second portion (7) engaging the surface of the first portion (2) in which the outlet of the cylinder (3) is located, and comprising a recess (10) located opposite said cylinder for delivering a liquid. A flexible impervious membrane (8) clamped between the two portions (2, 7) comprises an opening (13) facing the cylinder (3) and a resilient circumferential ring (12) engaging the bottom of the recess (10). A disc (14) in the central area of the recess engages the membrane (8), and a duct (6) linked to the cylinder (5) and having an outlet in the same surface of the first portion (2) as the cylinder (5) is connected to a liquid discharge tubing.

摘要： A liquid dispensing cartridge pump suitable for dispensing reagent in an automatic system includes a compressible metering chamber (13) suspended from a reservoir bag mounted within a rigid housing. Check valves between the reservoir and metering chamber and at a lower end of a metering chamber are formed of flexible membranes (15, 25) having apertures which close against conical projections on rigid disks (17, 18). The reservoir and metering chamber (13) pivot as a compression member (12) squeezes the metering chamber (13) against a back surface.

摘要： A metering pump (P) including a motor compartment (1) with a drive piston (2) movable within a drive chamber (3) having an inlet (4) and an outlet (5) for a main liquid, as well as control means (D) for controlling the movement of the piston (2); and a metering compartment (6) with a metering piston (7) in a metering chamber (8) connected to the drive chamber (3) and provided with an inlet (10) for a secondary liquid, said metering piston (7) being driven by the drive piston (2). The metering chamber (8) comprises its own outlet (24) separate from the outlet (5) of the drive chamber, and is separated from the drive chamber (3) by a stretchable tubular member (T) of which one end (27) is sealingly connected to a portion (13) secured to the drive chamber (3), while its other end (28) is sealingly connected to the metering piston (7).
