Abstract
A valve assembly for a dispenser for fluids including: a housing having at least an inlet opening and an outlet opening and a further opening connected or connectable to a fluid displacement mechanism, and a valve member including two parts translatably disposed within the housing, a first part for closing and opening the inlet and a second part for opening and closing the outlet.
Claims12
A dispense valve assembly for a dispenser for fluids comprising:
- a housing having at least an inlet and an outlet and a further opening connected to a pump for drawing fluid into the housing through the inlet and for pumping fluid from the housing through the outlet, the housing being fabricated from a polymer,
- a valve comprising a first part and a second part, the first and second parts of the valve coupled together by a single elastic element and the first and second parts translatably disposed within the housing, the first and second parts of the valve being fabricated from a polymer, the first part of the valve for closing and opening the inlet and the second part of the valve for opening and closing the outlet,
- an operating element extending through a wall of the housing and coupled to the valve,
- wherein the operating element provides at least three positions, a first position wherein the first and second parts of the valve are in resilient bias with the inlet and outlet respectively, a second position wherein the first part of the valve is withdrawn from the inlet and the second part of the valve is in resilient bias with the outlet, and a third position wherein the second part of the valve is withdrawn from the outlet and the first part is in resilient bias with the inlet.
