Patent ID: 8752737

Claim:
A valving arrangement device for an aerosol spray device comprising a pressurized or pressurizable container, said valving arrangement provided between an upstream and downstream fluid flow path sections co-operable to provide a fluid flow path between liquid in the container and a nozzle, an actuator mechanism for selectively fully opening and closing the valving arrangement, wherein in its fully open configuration said valving arrangement is such that fluid passes from the upstream fluid flow path section into the downstream fluid flow path section with a change of the cross-sectional area of the fluid that is less than 50% and with a change in direction of the flow that is less than 40°; wherein the upstream and downstream fluid flow path sections are moveable relatively towards each other with operation of the actuator mechanism to open the valving arrangement and wherein said valving arrangement is opened by said relative movement to allow said upstream and downstream flow path sections to come into register with each other.
