Abstract: An improved filling valve and liquid filling machine comprising such valve are herein disclosed. The filling valve comprises a housing having a base, a cap and a sidewall extending between the base and the cap thereby defining a chamber. The base has a ramp which slopes from a bottom surface of the base toward the cap. An outlet tube extends from said housing and has an inlet opening in fluid communication with the chamber. An inlet port extends through the sidewall to allow liquid product to enter the chamber. A plunger guide having an opening is provided on the cap with the opening extending through the cap. A plunger is slidably received in the outlet tube and the opening in the plunger guide. The plunger is movable between a position in which the plunger seals the outlet tube thereby closing the valve and a position in which the plunger is withdrawn from the outlet tube thereby unsealing the outlet tube and thereby opening the valve.
