Liquid dispensing device which delivers a pre-set, constant volume independent of the pressure and volume of the liquid supplied to it |
摘要 |
A liquid dispensing device delivering a constant volume independent of the pressure and volume of the liquid received comprising a cylinder which houses a mobile, sealed piston. The piston moves against the reaction of elastic devices owing to the pressure of a liquid supplied through an orifice of an ancillary cylinder. A valve associated with the shaft of a small piston mounted in a mobile fashion in the ancillary cylinder controls the flow of the liquid through the orifice. The small piston is moved by the action of a plunger against the reaction of elastic devices. The plunger is controlled by a thermoactuator.
